1994 Chevrolet Camaro - Shuts off while driving? Please help.. Sign In

I have a 1994 Chevrolet Camaro. It starts and drives, for the first 5 minutes or so it seems as if it has no problems. But then out of nowhere it starts to stall. I'll push on the gas as I feel it giving out and it will just shut off. If I let it sit for a few minutes it will always start backup and go but surely enough dies out. Its not the fuel pump, anyone have an idea what the issue might be?.. Bought an OBD 1 scanner it won't read it.

It has a 3.4 engine the 8th digit of the Vin is "S" and it doesn't have stamped multiport. It's a throttle body. It doesn't automatically restart..you have to shut the key off and let it sit then it always starts back up.

The problem ISN'T that the car won't start, it starts fine. The problem is that while your driving the car after a good 5-10 minutes it shuts off as your driving

Hoping to have it running soon, appreciate any info! Thanks!

What is the fuel pressure as the engine is stalling out?

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.


Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
