Will crank up an go dead ,crank up again an go dead

THAT IS CALLED A DEAD STARTER OR NO CRANK . condition. period.
6 TO 10- CAUSES of dead starter.
WHAT WORDS AND GOALS (stages)
CRANKS (key to start/crank) or button start /stop pushed for start.
STARTS (loud cranking heard if engine is dead)_
AND RUNS (grins)
AND STAYS RUNNING, (bliss)
IN THAT ORDER ONLY, MY CAR PUSH STARTS SO GOES FROM PUSH TO RUNS,. JUST 2 STEPS(stick shift bliss this) M/Tbox.
when kid 15yo id park on a hill and do rolling starts. 3 speed manual box then./

turns over means zero, (turns = spins the starter spins and if lucky the engine crank shaft spins or turns and if lucky starts.
turns never means runs. ever. it is called RUNNING.
some call running at idle others (old) say engine ticks over.
yes heard all the slang but do avoid TURNS. and OVER.()roger over and out)

I just fixed my neighbors, the hood knows i diagnose cars for free, retired me.
her car the battery reads, 10.7vDC (truth here is only discharged)
2020 Nissan.
head lamps bright, proves nothing here. at all (unless fully dead lamps)
the battery pushes 5 amps to head lamp but can not muster 100amps to the starter. so starter is dead or after 10 tries. tiny clicks heard under hood.
I see dash lamp dim a bit at crank attempts, a huge clue there.

causes. are: in order.
including lies the BCM dash lamp tells. (key IMMO failure lamp glows)
a huge lie there, 2020 car, and I know why the 10.7vdc battery causes most computers on board to lie or be dead.


(fast forward, only here the battery is dead. and no DTC ever stored, after cure.

PCM OBD2 jack we scan the under dash jack, shows comms dead, CAN_bus dead (her car)
and expected by me. (took 20min after my full charge the cars electronics to work again, ) NOTE THE DELAY.
now your causes all and in order
battery lugs, loose or rusty or both
no battery ever lasted 17 years, so is on 2 or 3 battery now. or due for 3rd !!!!!


on the gals car above the tag top-o-bat reads 2020 see? I always look at tags.

1. battery lugs ok, and clean', battery not 7 years old or more.
2. battery voltage not 10v but 12.6vdc , rested 1hr. is it? if not charge it.we ran a 75ft extension from her house to street to charge it. with my charger.
3. or drag the battery to the work bench and charge it. or to any shop,say test it. this battery in hand,.. (way cheaper than any tow truck) or jump start it.
4. my load bank test shows hard failure, even no load, and BAD shows on dial loaded, but the battery in here car is good, and fails this test.
5. next up, charged, the IMMO key lamp must not show failing key,we tried both. keys.
6. starter relay bad.
7. PRNDL fails at start in Park and Reverse both, or just park. bingo SOLVED
8. the starter is bad, even hot wired it fails keys not near car.
9. simple failures here, just a starter not the 50causes of engine failure.

I only jumper cable start cars if in some kind of panic (stalled in snow bank)?
I charge the battery first with the tool called a battery charger.
this is more safe for electronics old relic chargers can push 20vdc and never is that safe for modern cars(computers max).
my charger is a smart charger.


this one is real good, 1hr charge and it is 90% charged, from 10.7v.

P0102

& B2799 no engine told and is engine problems. of 3.
2.4 gas and 2.4 electric gas/hybrid! and 3.5L V6 ?????????????
no vin told, the 8th digit (usa) is engine code, learn to share that.

so the starter motor spins fast and engine too spin but will not start.?
the word turns over , means zero in the real world.
the starter spins, (turns) the crank shaft turns (if lucky spins) and the engine starts and runs and stays running. a serial process that./
worse yet?
other say turns means engine runs
turns over means ZERO to me.
.
or
cranks fast? but will not start? or runs for 1 to 10 seconds and stalls.

try to know we are blind and deaf here, we can not hear you turn the to start via key, and matters huge. this.

you put in a new battery and all I can do is scratch my head.
and think gee your starter was dead?. starter motor dead.
or not charged up.<<bet this I do. (blind)


P0102 MAF reads low, ( means weak and when weak engine power will be WEAK) the error means really SUPER WEAK or dead even.. or starter + battery weak causes fails error.

& B2799 IMMO errors
RULE #1 is:
to fix any cars even DIY the cars battery must be kept fully charged using a tool of same name a battery charger on any engine
that fails to start and or Alternator is dead.
must.
or the computers on board lie to you , with weak battery for sure cranking down and draining the battery too low.

b2799

Error in communication between hybrid vehicle control ECU and ID code box...

so is is the Hybrid car and you never told that.
wow not good for you and getting wrong answers and guessing
wrong.

B2799 is also listed as IMMO comm errors max.

my guess you keep cranking the dead engine
and the computers on board tell you lies

RECAP
no engine told. not one clue
not told if starter motor (cranking) is dead, weak slow or you cranked the dead engines battery flat

tow the car to a real shop.
they will charge the battery first and load test it
then crank the engine. and see if it starts.

OK what to do now. besides tow to shop
check call fuses.
charge the battery 100% and keep it charged or you will not make progress fast. OR NEVER.
TURN (THE ENGINE/START/STOP BUTTON DEAD?
LOOK AT THE DASH CLUSTER AND IMMO LAMP
kEY NOT DETECTED.?
THE IMMO LAMP MUST BE HAPPY(GLOW)
IF IMMO FAILS USE THE 2ND KEY TOY GAVE YOU DAY1 NEW
YOU HAVE 2 KEYS, UNLESS YOU LOST THE 2ND
OK IMMO HAPPY
TURN THE KEY TO START, AND CRANK THE ENGINE
IF WILL NOT START ADD 5% (A TAD) RIGHT FOOT THROTTLE
STARTS NOW?
IMMO ON THE CAR IS A MESSAGE BOX, ERROR
"KEY NOT DETECTED"
CAR HAS PUSH BUTTON START OPTION?
DO NOT HAVE BOTH KEYS IN THE CAR AT THE SAME TIME.
THIS CAR HAS 2 KINDS OF START SYSEMS
KEY OR KEYLESS.
THE LATER IS PASSIVE KEY FOB. ONLY
AND HERE ARE THE IMMO RULES IN YOU MANUAL

see the IMMO lamp up top. see the car body ICON with KEY symbol there. this lamp must not act wrong/
if does , this must be solved first.
IMMO means IMMOBLIZED.
the smart key , uses display message. no key detected

REDUX 1.
NOW KNOWn THE BATTERY IS NEW, but long sessions of CRANKING will make it dead (discharged)
and that you use the wrong words for engines
I guess petrol engine not diesel.
is this auto transmission or manual "STICK"

I think you just used the word CRANK for RUN
that makes sure all my answers will be wrong,for sure doing that.
here is what happens on modern cars.

1key on.
2: immo lamp very angry not happy engine is immoblized next.
3: key turned to ST (start) this means cranking the engine with a stater motor.
4: the engine starts, (and dies 3 seconds if IMMO is not happy< can be look at lamp IMMO)
5: engine runs now, and
6: engine stays running, and does not stall if does stall now say the stall word.

there are 50- reason for engines to stall. and a box of tools gauges, in my kit to find them all and not one do you have. nor how to.(find a shop get the car fixed,)!


if that starter motor is silent say so, or if it clicks or chatters say so.or makes huge BANG spins super fast but engine crank shaft does not turn(see all the ways starters can fail, hint , lots and I can not hear yours.

if starter fails dead then shift PNRDL from park to Neutral and crank the starter in N. (cured?)
key on, CEL glows normal and IMMO not happy can glow.
key on does IP cluster self tests and most lamps there go dead after the key on self test., not all.
modern cars are smarter mine cuts dead all lamps for faster better cranking power, 300amps from battery to starter motor , none wasted on lamps for sure head lamps on my car are disabled cranking,(mine)
what matters is
all fuses good
starter motor aways works.
engine starts
and engine runs and stays running.
and now running the CEL lamp does not glow or worse flash.
tachometer works
shifted to drive does not stall the engine,
car moves, if all is well the the transmission upshifts, 1,2,3,4, etc.

if fails scan he PCM first.

take to the after market alarm seller/installer.
or have it removed, totally and back to stock so that repair shops can fix it and not need Deity skills or ESP. to fix it.

and say
engine will not crank as the starter motor is dead
or say cranks fast that starter motor but engine will not start or stay running.
cranks ok or not/
or does not crank.
turns over means ZERO !

automatic transmission or M/t manual stick shifted, not TOLD.
4.0L INLINE 6 BANGER, (a great engine for SURE)
owned me a 88 and 98 Cherokee and all books then and now .
old cars have many problem mostly ignored until more more problem sinks the ship.(holes in the hull)
first off PLEASE stop saying turns, use these words
the the starter motor "cranks" the engine or not
or starter motor cranks fast (robustly)_ but the engine "fails to start" and run and stay running.

the addED throttle TRICK (gasPEDAL) TRICK HINTS AT 2 things, IAC dead or engine is flooding but a Dead IAC valve kills dead all starting air, so does WANT TO flood.
engine needs air and fuel to start lacking air is only fuel FLOWS , see? (HARD FAIL THAT)
that is an engine problem and next is lost of electrical power. of some kind.

that under dash problem is bad wiring, and only tests with a voltmeter (15 CAUSES)
can solve bad wiring, I can't just magically do that here. in a text box.
see? but must happen. (called car repair shop)

BOTH THE STATER MOTOR TURNS (SPINS) AND ENGINE CRANKS SHAFT TO TURNS, BOTH TURN,
JUST Avoid the word turns, and win.
starter works or is dead,
starter does work and engine does crank bingo if can start and even run the engine. (sustained)


say starter cranks.
say starter is dead, or clicks ,or chatters or is silent or spins fast but engine fails to crank, at all. (yes starter motors have lots of fail modes)
then a good starter
the engine crank shaft then spins, called cranking, action
if it does the engine may START< RUN and stays running or even STALL out. even in 2 seconds after starting. JEEP ASD relay drops out? ASD can drop out for lots of reasons.(ask)

if the starter fails, dead, then shift to Neutral selected.
foot on brake pedal, key on, and shift from park to N
and crank the starter motor. (starting mode of key)
this is a trick to always learn and try. on cars A/T.

you keep asking others all blind what is wrong.
and get wrong answers too. so what do you expect from the blind?
all that is silly game.
are you going to replace 15 to 50 parts on a wild guess.?

learn to diagnose. the problem using 2 things
a voltmeter
and the service manual drawing (schematics) to find the voltage
lost and point of failure, and learn not to guess expect 15+ things possible even more. I have the service manuals here.


also tell what these words mean?
"the power will come back"
i've no clue. at all
when this POWER deal fails do all other things work in the car.
all lights say head lamps key off or on? both
IP cluster lamps dead.????? the do a self test each key on,
tell al thing dead with key switch ON? !

WHEN DEAD, A VOLTMETER (DMM) FINDS WHY IT IS DEAD
YOU PROBING THE 15+ POINTS OF FAILURE HERE.

https://imgur.com/a/NEpNtRr

LEARN TO READ THIS SIMPLE SCHEMATIC AND FIND
WHY THIS PATH DIES DEAD. 0V, CRANKED (START)
AND YES KEY SWITCH IS 1 OF 15 CAUSES. SEE ?

FIX STARTER DEAD FIRST, THEN WE REPLACE IAC.(or clean it_
on all my 4.0L every one ,owned 3 at one time.
the top failure was a stuck IAC , i unplug IAC and remove it and clean it fully. (degunked) this elect valve controls idle air and RPM all the time)even cranked !!!!!!!!!
it loves to stick from that black cloud of EGR+PCV actions.
every 50k miles or less. I then got wiser, and spray the valve cone tip
with this, mine was 3 way acting PTFE ,graphite. and more.

• refused to crank (starter motor)? silent or clicks.dead.
• or cranks great and fast but engine does not start?

be clear or get wrong answers.
signals on dash? sure....
the IP cluster is full of error lamps, sure. so all those turned on?
key on they do turn on (self test lamps this is called)
then after a delay some go out and some stay on, this is normal
then you crank the starter motor and engine starts, and runs and stays running and all error lamps go out.
your users guide covers this, need one, it is free on all cars USA.
if starter motor is dead
shift to NEUTRAL, and crank. solved?
charge the main battery
jump start the main batterY?
Cranks fast and not starting is a whole other WALL OF TEXT
and up to 20 tests or more and 20 tools or more.

redux 1:
no engine size told, gas we now know GAS word but there are 4.
when did the truck LAST run perfect.? , last week, year, or decade?
is fuel bad and old 1gallon hints at old dead truck bring revived;, there is a story here.
does this truck have the IMMO option and key is bad? causing IMMO cut fuel in 3 seconds. Immobilizer? LAMP not happy????


2.5L, 3.9L & 5.9L , 4.7L Engine 3 transmissions used.
code 42RE; Trans. code 46RE and 45RFE

to fix any car the driveline there needs to be known and told.

1: check all fuses. if one blows and makes the network dead, (PCI dodge) modules can not communicate.
2; scan the PCm it will tell you 2 things. cluster can't communicate to PCM or TCM/transmission gross errors.


well cluster PRNDL errors means 2 things, cluster can not talk to PCM (network dead)_ or TCM'/ transmission errors, told with scan tool clear as day but nobody is looking or using lame $17 code reader not a real scan tool.

the network (PCI) in this car connect 10 module computer brains, in fact ALL of them and must not fail this network.

use a real scan tool and find what what is failing in minutes
a 2008 or newer tool is best, OBD2 (USA) real scan tool
beg /borrowed , rented, buy or loaners.

that is correct the battery needs to be good or 12v or rested at 12.6vdc or never below 10vdc. sure a battery charger may get the voltage to 12vdc, if lucky and battery cells not shorter, a 10amp charger is best at least
and charged for 4 to 8 hours first.

Isince it cranks, means you have power, elctric system is ok! I guess.. this could be a result of gas delivery problem... either a pump or gas circuit controller.... OR a small propable reason if you have an immobilizer (electronic chip on key!)... but there should be the securit key highlithed on dashboard...

It doesn't have to be the security. a dead battery won't let the car crank either. With a security problem the car will crank but not start. The security can be reset if the battery is charged and up. Turn the key on ( do'nt crank ) the security light will stay on if it needs to be reset. If it remains on leave the key on for 15 minutes around then it will go out. turn the key off and then turn it right back on, the security light will be on again. Leave the key on till the light goes out again, then turn it off then turn it back on , wait again when it goes out turnthe key off then right back on then crank the engine and it should start. With a scanner the code will be security neweds to be reset. Thia is all anyone can do to reset the security and it's what you were charged $450 for. Following directions.

i know your battery is dead but if you have a charger put it on then turn the key to the on position for at least 10 minutes until security light stops flashing then turn key off and try to start.
