I have a 91 camaro with the 3.1 V6. Sometimes, after I have run the car all day, like back and forth to school a few times, when I get home and say I go to go somewhere just a little bit later, It will not start. I have checked everything I know to check. The fuel pump does not get fire to it when this happens. It does get fire through the fuel pump relay though. What could possibly cause this to happen. As I said, It only does it when it has been cranked a few times and is warm. Any help would be appreciated. Thanks.

 

OK, you say that the engine cranks but will not start, and you get power to the fuel pump relay but not the fuel pump. Well i would advise ya to change the fuel pump relay and check for a short in the wires leading back to the fuel pump.
