Okay, I've searched and I read something about it being the main relay and I just wanted to double check that the main relay doesn't have to do with Warm OUTSIDE temperatures. I experience this problem in the winter time as well.

My car starts up fine when the engine is cold. After it's reached normal operating temps if I turn it off and let it sit maybe 10 minutes it will have a hard time starting. Sometimes I'll have to keep cranking it over and over maybe 20 times before it starts. It turns over it just doesn't seem to catch.. I can also hear the fuel pump priming each time.

Any ideas? It is extremely aggrivating. New Wires, plugs, distributor so I know it's not any of those.

Thanks in advance.

Motor is a GSR

 

Bump please help..

 

What did your old plugs look like? Do you have any performance peices on your engine? What is your compression ratio? What plugs are you using?
Verify your fuel pressure is correct and that their are no leaks. An old fuel filter can cause hard starting. Could have a leaky injector. Their are a thousand things that could help you out. PM and I can walk you through what you need to do!
