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 that.car . (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
http://www.toyotanation.com/forum/134-6th-generation-1988-1992/
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.

SOURCE: 1995 Geo Prizm won't start

I just checked the battery connection and what I thought was a good connection wasn't. It need new connectors on the post. Runs fine after I tightened them more.

SOURCE: 97 geo prizm has fire and fuel wont start

check all your relays with an ohmeter to make sure they all operate. A code would go off usually only if it is an electrical problem. If you are getting fuel and fire, and no codes it is most likely a relay. If you did have codes then I would say sensor. So check those relays

SOURCE: 1993 Geo Prizm Lsi Harmonic Balancer

Yes a harmanic balancer from tha corolla is the same thing. I had to do the same thing with my 95 geo. It works out to be a lot cheaper buying for a toyota than a geo.

SOURCE: 1994 Geo Prizm LSI running one day won't crank next day

turns over and crank are the same thing,
so you are saying it does crank over but no start,right?
you need to determine if you have at least 50psi of fuel pressure in fuel rail at reed valve.

blinkers on , key off>?

which engine?

http://www.fixkick.com/PRIZM.html



the engine type dictates what wiring car has. (partly)



fix the stuck blinkers first. this implies, either ignition switch failure

or gross wiring errors, hacks gone wrong.

the key swtich does turn off blinker power feed.

My 93 geo prizm wont start.


If the engine will not crank, a mechanic would check for voltage at the starter, the neutral safety switch or clutch switch, and the key switch.

1993 Geo Prizm 1.6L Won't start and has no spark at the spark plugs. Distributor coil seems fine. Got one from junkyard and got same reading from both through meter. Lights come on and windshield wipers...


Hello!
Can you see if the rotor in distributor is turning whilst engine is cranked? or if the Cam is turning by looking through the oil filler while someone turns the key.
If they aren't turning/revolving then you may unfortunately be suffering a timing chain/belt failure.
Sorry to bear bad tidings if this is the problem.
