Hy My 99 forester S doesent start. Has new crank and cam sensors and so on . I think immo is on ? Red key on the dash

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.

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

no engine told , fuses (all) not checked. PCM not scanned for errors
cranks fast but will not start and run and stay running.!
right-o?
the car came new with 2 keys, lost both>? or lost 1 and now the other is dead, and the IMMO lamp on the days screams bad key bad key and not reading the glove box users guide (free ) to see how the lamp works, IMMO (thieft/security) >
i will now read page 81 in your guide to you. and linked

When you turn the ignition switch to ON (II), the Immobilizer System
indicator should come on for a few seconds, then go out.
If the indicator starts to blink, it means the system
does not recognize the coding of the key.
Turn the ignition switch to LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II) again.

USA dash cluster here, not told you, the country.
immo lamp is key icon, and must be happy or the engine cannot run.

Hi Joan Whittaker,what does no crank mean.
the starter motor is dead? some posters call d crank= running engine.
which engine there? cranks fast but will not start.
underhood fuse box f24 blown?
step 2 after all fuses checked is:
shift to Neutral see if that allows cranking per my red circle below
is PCM control.
is the dash IMMO lamp happy?

as you can see the pcm decides to do the cranking or not
via its starter relay.
if you scanned the PCM it will tell you why it id not start.
immo error OR A/t PRNDL (TRS) ERRORS. OOPS




the IMMO page in your users guide covers IMMO
if key 1 fails try key2, car came with 2 keys new.
READ ALL PAGES ON IMMO FIRST

If the engine does not start and the Security System
Light comes on
Security System Light (CLUSTER LAMP ICON LOOKS LIKE CAR CUT IN HALF WITH A PADLOCK, never ignore this lamp.
This light flashes when the Theft
Deterrent System has been
activated.



https://www.manualslib.com/manual/1078925/Cadillac-Cts.html?page=256

all that and not 1 look at the dash IMMO lamp ?
and it not happy? page 2-13 in users guide. glove box found. or free at nissan or found googling 100 places.
READ your free users guide that page on IMMO
and NO START

immo lamp is "Security" glowing wrong.
this lamp stays on key on , that means IMMO is failing.
for that KEY car came with 2 keys use the 2nd key
never have just one key.
cranks fast and will not start
or starts and runs for 1 to 10 seconds and stops
IMMO lamp trying to get your attention and can't?
not oice checking all fuss
not once scanning the PCM in it tells you why it fails.

now if immo is happy?
there are 50 causes of no starts
engine bad or EFI and all sensors and more. bad.
there are only 2 paths here.
do that tests or get the car repair in a shop.
to do test one needs tools got them?
Learn that EFI is what keeps an engine running

& sustained and spark good fuel pressure must be at spec.

WRONG SENSOR USED
CRANK AND SCAN PCM AND SEE WHY.
THROWING WHAT DTC CODE, NOT TOLD.
cmp cam sensor, not ckp crank installed wrong?
some sensor must be shimmed to work service manual tells that.
no engine told of 5 or VIN so I can tell you.
engine cranks fast and will not start
or does not crank (dead starter motor) now.
IMMO lamp on dash happy>? if not spark is cut

there i lots more to any starter, the permissive's
here is the list (and voltmeter tests for each)

1. battery good. 4 lug ends clean and tight. no rust.
2. all fuses good (oops forgot all those?) cab/bay all.
3. key gets 12vdc power and ST pin goes hot cranking.
4. PRNDL switch closed for park IF FAIL CRANK IN NEUTRAL
5. OK STARTER RELAY CLOSES.
6. NO IMMO FAILURES, lamp on dash happy.
7. starter solenoid small lug goes hot, 12vdc
8. starter cranks if not bad. or engine not seized.
9. any tech knows how to hot wire any dead starter (keys in pocket)

immo mostly cuts spark then fuel but some rare cars cut ALL
if battery is bad, yes head lamps prove little, we jumper cable crank all dead starter now, watch the tow truck guy see?
Heads are 10amp starter is 300+ amps, apples and oranges not the same, see?

or get the car fixed in a shop as 99% do.
learn and do or get it fixed.
guessing fails mostly, use a voltmeter find the path to the point of failure,
keep that new battery charged or now you have 2 problems to fix.

new brain is a fail.!
the brains are NOT PNP, NOT plug and play, period
so now car has 2 problems. oops. one real,. and one caused.
not told what engine is there?


not told is starter dead, cranking is silent.?
or cranks fast but will not start? and run or only runs 1 to 10 seconds?
is the dash error lamp RED ball IMMO lamp glowing wrong?
try the 2nd key jeep came with, new day1?

wow cathy 4 post now.
get it jump started, does it start now?
charge the battery to 12.6vdc rested
does it crank now, you mean it wont crank or
cranks robustly but will not start
or cranks and runs for 3 seconds.
is the IMMO light off, it has its own lamp, mine is sold read, no words, no icons, just red. if on, it WILL NEVER RUN.

key on
cranks does it crank.???
if not jumper start it. if IMMO is off.

you mean the IMMO (immoblizer?)
the IMMO does not block cranking
but you never said ,
does it crank? if it dont crank it sure cant start. ever. (i can push start mine.....m/t)
did you pull the alt with the battery neg. lug connected (bad that)
if yes, you blew a huge fuse. inside engine bay fuse box,
are many dash speed lamps dead?

post what it does , does it crank, and not start or not crank at all .???
what do the dash lamps do key on?
CEL , OIL and charge lamps ON< key on?

Dear sir I think you should check the engine tempreture sensor . I understand that starter work but if doesent you have to check the fuse box there is a relay it may be not working
