Ford fiesta,1996,petrol,fails to start.

so the engine is dead.?
the IMMO lamp means , engines is now Immobilized
lost the 2nd key, car came with new?
called SecuriLock
the uses guide, tells you what to do, sure lost it.
just the lamp fails but engine runs and drives ok? not told primary function of he car.
page 117 covers this topic. in the glove box guide
here it is.
SecuriLock

https://www.manualslib.com/manual/52993/Ford-2000-Explorer.html?page=117#manual

'the key off flash means it is working
key ON, flashing is bad.
When the ignition is turned to ON or START, the theft indicator will
light for three seconds and then go out. If the theft indicator stays on
for an extended period of time or flashes rapidly, have the system
serviced by your dealership or a qualified technician'

THEN I SAY.
this same page forgets, (ford is daft) to say
TRY THE SECOND KEY NOW. (DO NOT HAVE 2 KEYS IN THE CAB AT THE SAME TIME,) JUST 1. KEY, AT A TIME.

AND PAGE 116 TOO . REAd that
too.

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

Have you tested to see if the starter is good?

The brake warning light should not affect the truck not starting...most of the time is because of low brake fluid or the emergency brake is on. To check for codes you should just turn the key to the on position and you need to try resetting you anti theft light.

use the 2nd key car came with new.?
if that fails only a auto locksmith or dealer can fix IMMO

auto transmission or STICK???????????????\
all fuses test good?
what does turn over mean to you?
there are 3 answers
the starter spins all by itself and turns over,
if lucky the stater can even turn over the cranks shaft, called actual cranking over .
we say it will not crank or it does.
or we say
the starter cranks fast and he engine and will not start and run
or it may start for 3 second and stall ( a classic IMMO trick)

if the starter spins the engine robustly and fast why the new battery>
must be a no crank engine,(silent starter.,clicks or chatters or sound like bombb under hood a huge giant BANG< a seized engine,.
this is 10x more easy than a dead engine for sure.

1. :battery drained. so charge it.
2. battery load tests and charges fail the battery is bad
3. so battery new ,failed to help cranking. sorry I cant hear it. sure.
4. crank not in failing Park but now in Neutral , works?
5. ok all that fails. must be bad starter. WE HOT WIRE TEST THEM.
6. some rare cars the IMMO even cuts starter dead, not just spark/fuel. so is the IMMO happy light glowing or not.

FUSES GOOD
iMMO LAMP NOT ANGRY, (FAILING)
SCAN pCU, SEE IF THERE SAY BATTERY ERRORS ETC. DTC CODES.?
CRANK IN neutral not just park.
HOT WIRE THE STARTER.
JUMPER CABLE CRANKING WORK.?

OK FOUND IT YOU DID DOING ALL THAT.

May 29, 2012 - Uploaded by georgef551 I found a start-up flaw in the Ford Fiesta, when I occasionally tried to start the car quickly, and... ... this happened. I had them either fail to fully turn over, or other CPU-based starters wouldstart up the vehicle. ..... Ford Fiesta 2004 Lx 1.4 petrol mk6 won't start help ! ... 2012 Ford Fiesta Zetec 1.6 TI-VCT. Start .

Im thinking your starter switch.

hybrid or not, what engine I4 or V6, got IMMO? just a clue?
all fuses>? ok? that is first on all elect failure including EFI.

The 2007 and hybrid both have immoblizer options, yours?
pager alarm? after market stuff? hacks? call them...... yes.
IMMO cuts fuel if anyone attempts to hotwire the car (like on TV malarky,see movie PARKER, what a joke.)
The IMMO signals bad key or good key code, does it?
this is in the operators guide , is it lost?

turn over, what does that man.
dead starter motor (dont spin or turn over)
or the engine does not turn over, due to above dead starter?
no crank?
or no start? are 2 different things.
i looked up the IMMO schematic and it does not stop the starter.
it only cuts fuel
so if you mean the engine does crank and the engine fails to sTART.
then check the IMMO responses. if ok. or not.
check for fuel injection
then check for spark;

Have the battery tested, the symptoms all indicate the battery has failed the secir
