I have a 96' z28 when it is cold it starts up fine but when it gets hot it hard to start acts like it not getting gas. I have replaced the fuel filter,fuel pump,spark plugs, wires and distributor. But it still doing the samething, but once it started it runs fine and have all its power. I have some 02 heads and headers on the engine could the cause a problem.

 

hay chevboy welcome to the forum. i made a thread and moved your post for you. it sounds to me like your starter is failing when it gets warm/hot. have a look and see if your heat shield is still there.

 

thanks will try that.

 

This doesn't sound like you're describing a periodic dead starter (engine doesn't turn over) issue. Are you getting an "engine cranks over but no start", or a "no crank at all" (starter goes click or less)?
