I'd have to go with the ignition coils.If its a six cylinder you'd have three coil packs,two terminals on each pack.The ignition module is under the coil packs.

98eagle talon won't start,it turns over but the motor won't start.what could be the problam

Hi William:
2 ingredients:

Fuel - Has to be getting into cylinders.
Spark - Hot blue spark needed at tup of spark plugs

Either you have run out of gas, or a component has failed.
If you have spark, I would be suspicious of a fuel pump failure so would check fuel pressure. Should be about 40PSI.

Stalling when turn back on

all stalls end in CEL check engine light on. that is normal
but CEL glow. when engine running , means you had a failure, and it stored DTC error codes, so scan it.
lots of causes. huge list.
get a tune up , tops list.

SCAN it to be sure all sensors work. running.
all fuses in car good.
by stalls , i assume the engine stalls and engine RPM is 0 RPM.
the stall cause the whole dash to light up, all the warning lamps come
on (self test) oil , charge , CEL. come on.
what is important is the stall and the cause.

i will tell you the 3 ways.
lost electrical power to engine EFI system (seems not)
bad engine, (lost compression hot)?
bad spark , spark died.?
bad fueling, lost all fueling (starves and stalls or floods and misfires horribly and stalls (black spark plug tips are big time clue)

if non eof the rings a bell.?
get the car serviced.

this car is newer nicer car, you (we) can scan and drive and log data.
allowing faster easy diagnosis.

The car turns on, after 3 or 4 seconds the car shuts off.

expensive guessing there ,wow !

why not find out why ,by using diagnosis, its far cheaper, i promise.
engine stalls:
A: can you save the stall>? with a fast right foot action????
yes, then its not 12vdc power lost to EFI system.
no, then it must be lost spark or lost fueling or flooding.
did you do the full 60k mile tune up yet? and the 90k? ever interval?
your mech. can't find this? is that what you are asking.???

stalls list, near impossible to answer not knowing, test A: above !
but here goes.
1: lost 12vdc power, EFI dies. engine dies. volt meter saves day.
2: lost spark, (cant save stall, test A, for this or lost 12vdc)
3: lost fuel pressure , stall can be proven with using test fuel at stall point. (spray fuel into intake) below 30PSI fuel, on all cars is bad.
4; flooding, from too much fuel pressure, say over 60psi, causes flooding, leaking injectors, so an injector leak down and balance test shown in the FSM.
See soaking wet spark plug tips (free easy check)??? flooding.
fast foot easy prevent stall, ? yes, ISC stuck closed. clean it
harder fast foot save is EGR stuck open. clean it.
impossible fast foot save is , #1,2,3 above.

all above can be tested easy and with cheap tools.
the engine runs by order. "classic list"
do the tune up.
1: 12vdc to EFI ,key on, all the time.
2: engine compression at spec, or 150psi. 90k timing belt ignored?
3: good spark and timed right. (strobe light test)
4: good fueling (not lost , or flooding)
5: EGR not stuck open, ISC not stuck closed.

this gets most stalls.
if fuel pressure is at bad shunt levels, +60psi , due to the fuelpressue
regulators stuck closed. (in side tank it is so is fuel filter.)
the engine will flood , i check fuel pressure. way before any ECU swaps. infact i check all ECU inputs first. and fuel pressure must be in spec range too.
good luck.

No power won't hold idle

stalls. (hot engine, cold engine, both?)_what engine of the many.?
lost engine power. sure that will stall any motor.
ever tune it up r, or do the 60k mile service points, EVER?
if car was serviced, we can then say
1: lost 12vdc to EFI and spark , did dash lamps all go dead at stall.
can you save the stall with a fast right foot. (big clue there !!!)
2: lost compression hot. (guage it)
3: lost spark. (tests)
4: lost fueling, or floods more simple tests, ask if not known.
5: EGR main valve stuck wide open.
6: ISC stuck closed but will not stop power, or fast right foot.

lost fueling can be just the skippped, 60k fuel fuilter swap.

Starter turns but does not start

what year car, what model and sub model and what engine.
lots of honda's from 1969(70'market) which one.?

no start, can be one of 3 basic things (generic answer ASE)
lost electric power to fuel or spark systems (Blown fuse?)
1: lost of compression 1 more more cylinders
2: lost spark 1 or more spark plugs.
3: bad fueling , too lean or too rich.

if you have spark times number of cylinders
then try test fuel, if test fuel runs car for 3 seconds.
then jump on why the fueling is dead.

In gear but wont move

what engine/ there are many.
since you dont know, i must guess.
here goes, in generic form
1: is it the engine power lost or transmission failure
if you dont know, ask any mech to tell you, in 1second flat.
2:lost engine power (guess2)
a: lost electical power 12vdc to critical EFI parts.
b: lost compresson.
c: lost or weak spark no bad timing spark.
d: bad fueling.

that list works for all modern cars. if tranny is a M/T say so. now.

1993 geo prizm chaned coil but still when it gets warm has no power engin light comes on and ca turns off then wont start

wont start forever. (parked for 24hrs?) i presume it cranks at full speed?
this is a gen 6 toyota , you can learn best on this car by using
forums for . (true for most Geo's off all kinds)

first off ,never work on any car, unless you now what engine you have (power lost? what engine is this.)
there are two 1.6L and a 1.8L toy engines used on this car.
tune it up yet? every 60k it needs that. did you?
if not turned up (called today "SERVICE POINTS" )

no power cold or hot block.?
if hot ,it fails,only, does it reach and hold 180F coolant temp.or more.?
if not?, halt. the ECU will not work right with a bad thermostat.
when it gets warm, does that mean cold power is good?
and ca (car?) turns off, then wont startca? sorry for big letters that is how it pasted. No font controls.....

my best guess. is you mean,
car runs perfect cold engine, starts ok.?
then i drive, engine warms,and has lost power.?
then, the engine STALLS, and the CEL comes on (all CEL do that, the CEL comes on just before the stall passing 300RPM)
it means the ECU has good Elect power, but the engine is stalled the
tachometer reads zero RPM proof of stall and no forward movement possible. CEL popping on, means Engine stall.

the ca turns off?, my guess is that means car, (engine) turns off, stalls. (

Ok this is a simple post. it's
car hot stalls.
am i correct?
off the wiki, quote (knowing the history facts solves 99% of questions, (how to fix or get parts)!
1990-1992 Geo Prizms were powered by the 4A-FE or optional 4A-GE engine. i think no 1.8L yets
so what engine?
i can not stated history on the 4a engine due to Toy using different
updates on different years. (complex)
Geo Prizm base model (based on Toyota AE92 chassis) 1989-1997
read about the AE92 here
a total of 4.5 million of this generation (AE92) made.
wow, no wonder so many posts here for 92s;
now the forum, just or this car. its the 6th gen car at TOY. not 1st
now the stall question last. (in the most general terms( basics its called at ASE school)
all cars, 1920 to now
the same answers.
1: lost electric power 12v to key EFI parts. (or 6v in1920)
2: lost engine compression, if engine has lash setting now is the time..... yes, 60k service point skipped too.
3: lost spark, test for spark at all 4 spark plugs not just 1.
using a new and gapped proper, test spark plug. repeat 4 times on all cyl.
4a: no fuel? (simple tests ,asks
4b: too much fuel. called flooding, (simple tests. all)

on a car this old, about 1/2 of them the timing belt slipped.
at 60k mile mark, it's a mandatory service, up to 100k its failure time.
when?, depends an 10 facts, none that i care to post now. you can ask.
the above fail points can stall any engines, as can:
stuck open egr, (love to at all stop signs) clean it , its a 50k service point.
stuck close ISC (electric iAC) clean it.
melt solid bricked out CAT converter. easy tests. too rich engine kill it flat as it glowed red hot to the moment of collapse.
this last failure can even prevent the engine from starting , fore ever.

for best help post no starts to the forum above, or?
they have drawings and other magic there.

I was driving my car and when turning i lost my power steering and brakes when i parked i turned off the engine and after that it wont restart. later on we found that the sparks wernt getting any fuel but...

Question?? did you lose your serpentine belt, so your lost your power steering and then the engine died. Or did the engine die and then you lost the power steering??? If the engine died, may be the fuel filter has reached the end of it's life and dirty and needs to be replaced, If the engine was running and you lost the serpentine belt, the belt may have taken out your crank shaft sensor, so the engine does not know when to command the #1 injector to fire to get the engine to start. Keep me posted, be glad to help you get your car running
