No, it would still start and run for just a brief minute or two, before too much back pressure killed the engine.

Have you checked for spark on a spark plug wire? Another test is to spray some starting fluid into the throttle body intake and try starting. If it coughs and tries to run for a few seconds, you know that gas is not getting into the cylinders-either a bad fuel pump or an injector circuit problem. If nothing with the starting fluid, it must be an ignition problem, so start by checking for spark. If no spark, possibly the ignition coil, the ignition control module (but this may be in your new distributor), the crank position sensor, or rarely a bad pcm- the engine computer.

Yes it is possible for a plugged up cat to prevent any car from running. Before you replaced all those parts you should have done some troubleshooting first. Are you getting spark at the right time on each cylinder? It is also possible the timing chain/belt has slipped of broken and this would not only cause the timing to be off but your car would not run. when you replaced your distributor and wires did you make absolutely sure it went back together exactly as before? If the above is all or mostly greek to you, you need to find someone who can quickly troubleshoot for you. First have them check engine codes. Second check the timing. Third have them check for proper timing and spark. Next have them check for fuel delivery at the fuel injectors. Then if all the above checks out ok, checked for a plugged exhaust system.

    No codes showing. pulses to injectors good . Haven't checked compression timing belt isn't broke

  • Jonathan Graves Jul 07, 2014

    Based on the fact that it will run briefly and no codes (no check engine light) then try disconnecting the exhaust just ahead of the cat and see if it will run. another sign the cat is bad is if it gets real hot - but it probably can't run long enough to do this right now. preceding this not running would be poor power through entire engine rpm band and poor milage.

    oh ya when trying to start if I put my foot on gas lead it seems to want to start but I don't want to crank it to long. then when I stop cranking it sometimes makes a glug glug sound like when you ld hear ummm like when you crank a dirtbike motor. that compression sound., tried starting fluid ,nothin

  • Jonathan Graves Jul 07, 2014

    Yes, sounds like a clogged cat, though a muffler can corrode and plug up as well. try disconnecting the exhaust ahead of the cat first. if it starts and runs that is your problem. if so replace your O2 sensor at the same time as the cat because it will have run too rich to be effective. if after disconnecting the exhaust it doesn't want to runmake sure you are getting enough pressure out the exhaust pipe. if not you need to check between your exhaust manifold and the end of the pipe ahead of the cat.

If the distributor is installed properly and fuel system is good it would still start but have little power and get hot fast!
If it is firing and getting fuel the timing may be off.
Hope this helps!

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.

SOURCE: 96 geo prizm 1.6l.

I would definitely try the distributer cap and rotor button. It's about a 15 minute job and might solve your problem. As the car warms up the electrical components of course heat up too. As the heat goes up, resistance also increases in electrical connections, wires, etc. You could be getting enough current to pass between the rotor and the poles at low temps but, as they heat up, sufficient current for a good spark is not being passed along.

1992 geo prizm start but won't run we have changed the fuel filter fuel pump distributor cap and rotary button coil pack battery and alternator plugs and wires the catalytic converter was glowing red

Sounds like the cat or muffler is plugged. If there is an 02 senor ahead of the cat or muffler take it out and see if the car will start, it will run rough but if it starts one of them is plugged and it most likely is the catalytic converter in the exhaust system.

My 1990 Geo Prizm GSI will start, but it won't keep running when the weather is cold.

Sounds like the automatic choke control on the carburator is shot! It is stopping the proper flow of gas from getting to the engine...replace it! Also make sure you have recently replaced the fuel filter; moisture in the gas will stick to the filter and freeze up making it hard for gas to get through!

Engine code 14 ignition signal and code 26 rich fuel mixture detected on a 94 geo prizm. i checked spark plugs, wires, replaced distributor cap, and fuel filter. where do i go from here?

I would start by replacing the primary ignition system,cap,rotors,wires,you can't just check these items they could be defective where you are unable to see.a rich condition can be caused by a mis fire from a wire,a bad tps,or 02 sensor,but I would always start with the basics and not overlook them,if you need any more help let me know.

My girls 1990 Geo Prizm keeps stalling. After it sits for 10 minutes or so, it start back up, but sometimes will only make it a block or two before dying again..It is an intermittant problem, but it...

next time it stalls pull the plug wire from the spark plug. have an extra spark plug with you and stick it in the boot. lay it across a known ground and turn the car over. its probably not firing.. sounds like its an ignition module faulty that acts up when it gets hot

1993 Geo Prizm is turning into a money pit. now it has an exhaust leak. It also sputters through all gears at the start. Could this be due to thw exhast leak or a bad fuel pump???

I don't think an exhaust leak would cause the sputtering in all gears. I've run my Geo in the past with a cracked exhaust manifold for months, and it ran fine, just a bit louder. Are your spark plugs & wires in good shape (missing vs sputtering)? Also check inside the distributor cap for corrosion/carbon build up. If all that is ok, then I would start with the basics: first try running a complete fuel system cleaner through it for the next two tanks, that should clear any partially clogged fuel injectors. If no luck, then replace the fuel filter, and try it, if it still sputters you can check the fuel pump strainer if it looks ok, then you might want to replace the fuel pump.

1995 geo prizm lsi starting problems.

There is a long list of possible causes, You would have to check into each individual one.

1.) Failing fuel pump.
2.) Bad valve seat/seal
3.) Sticking valve
4.) Timing is off, Reset timing to 10* BTDC
5.) Clogged fuel injector(s)
6.) Your new ignition coil (as im assuming thats what you meant by "Igniter") may be faulty.
7.) Wiring to the new ignition coil may be faulty
8.) Spark plug wires not firmly in place.
9.) Faulty Distributor pickup coil and/or wiring harness/wiring.

The list goes on and on, Some are more likely then others. Personally, from experience (having owned 4 95 geo prizms myself in my lifetime) i would go with the clogged injectors, Fuel pump, and distributor pickup/wiring in that order. Those engines last quite a long time when properly cared for, An internal engine problem (Although possible) is unlikely in my opinion.

95 geo prizm died

The timing belt may be broken.How many miles are on it and when was the timing belt replaced if ever.Timing belts should be replaced at around 60,000 miles.
