My sister has a 95 camaro with the 3.4L. Occationally after the car has been driven for a while, if you go to start it back up after its warm it won't start. If you let the car cool down it will start. We thought that maybe the starter was going out so we replaced that and it still does it. So hopefully someone can help me out. Thanks in advance.

 

did you replace the heat shilde back onto the new starter from the old starter? Heat is the major enemy of electronics on cars. It also could be something else cause like the ICM or PCM.

 

Im having the same problem... But not occasionally.. ALWAYS..
Did you find a solution..

 

check your ground wires. a bad ground will cause this.

 

Heat can affect the ignition module. Here's a trick to help diagnose. When the car is warm and not starting, spray starting fluid into the throttle body and immediatly try to start. If the car starts and dies, you have a fuel supply issue. If the car still doesn't start you have a spark issue.

 

ether is actually an enemy when it comes to i diagnosis within any electronic system. because ether ignites under the compression of each stroke, the motor is actually dieseling, or running on ether only with no spark. the "no start" mystery with the 3.4L v6 is an easy fix. signs will point to starter, fuel pump, pcm, etc... most of the time it is noticed, or found when the vehicle is shut down more than 3 or 4 times within 45 minutes. the vat (vehicle anti theft) system consists of the pass key, and the onboard computer. a large drop in voltage (rolling the windows down, turning headlights on, aftermarket stereo, or hitting the brakes) before starting will trip the switch in the vat. even a worn out key will cause this. the fix. new battery, new habits, new pass key, disabling the vat system, new steering column, or simply turning the key to the on/run position, and letting it sit for about 10-15 minutes. i have had the same problem out of mine. it is a very sensitive system. hope this helps. starting fluid is a last resort. good idea, but it should only be used on a warm engine to diagnose a fuel system malfunction.
