Stalls hot, cold or both>???? clues. matter.
which engine?

a full tune up?
by the book.
stalls have over 50 causes.
but are really just 4. Class failures.
a shop uses tools to fine true cause.
1: lost 12vdc power to EFI system. for any reasons.
2: lost compression on one or more cylinders.
3: lost spark. or timed wrong.
4: bad fueling, (too much , or too little) or lost air supply at ilde, ISC stuck closed causing rich and slow, running and stalls.

or just the EGR stuck open. this would fall under, #4
Do you want to test, or gue$$?

I believe the pin should be positioned at the top, but I'm not 100% on that. I'm going to say that the position you had when the fuel backed up into the carb is 180 degrees out on the cam, and that the valves were opening during the compression stroke, therefore blowing the fuel back instead of pulling it in. If you know where the gear was during this, then take it off, go a complete 180 degrees with the cam, and put it back on. This should get you close enough to for the engine to start, then you'll need to dial it in.

SOURCE: my 94 geo prizm sputters and jerks during

for that cost you could have taken it to a mechanic and had the compretion tested, that is what needs to be done. at least 90psi and all cyliders sould be within 15% to that.

Your ABS light is on for good. It will not shut off unless you fix the brake system which is usually more than the car is worth. Most people just use black tape. I took out my bulb 10 years ago. The brakes still work fine, just no anti lock brakes, i never noticed a difference. I had another guy say his car wouldn't run when the light came on, I never heard that before. Hope this helps.

Stalls when put into gear

many things can cause this. the most common problem would be that the timing is slightly off. (fixed sometimes by adjusting the distributor) it could also be a bad fuel pump (or clogged fuel filter) this would allow enough fuel to run the engine in park but not enough to run the engine under stress. clogged air filter could also cause this (not allowing enough air into the cylinders). I would change the air filter and fuel filter. then crank the vehicle and slowly turn the distributor (finding the best idle position) then see what happens. lastly replace the fuel pump.

After unusual below freezing weather here in california my 94 prizm is idling really rough and sputters in gear what might be the problem

Sounds like water in the gas. Colder temperatures can lead to condensation in the gas tank. Water then enters the fuel line, causing sputtering, rough idle, and occasional stalling. Try a bottle of Dri-Gas or other similar product with your next fill up. If the problem persists, you may need to change your fuel filter.

Bad gas / geo 95 prizm

I would try using a fuel system cleaner from the auto-parts store and change out the fuel filter. The gas additive will help clean out the fuel injectors and the fuel filter maybe need to be changed anyway because of the age of the vehicle.

A clogged fuel filter would cause this problem.

Do a complete tune up plugs wires cap rotor. The spark gets stronger when your accelerating and this is when some electrical problems break down.

Bucking problems with a 94 Jeep Cherokee

if you have not put a fuel filter on yet i would, and then do a fuel pressure test. if filter don't help and pressure is wright, might be water in fuel. do fuel filter, pressure test, fuel additive, might be cheap fix. if what i said don't work, and everything else checks out ok, then the only thing left is fuel regulator. but also don't loose sight of it being electrical too.
