Steve, check your starter relay, as well as your starter itself.

I checked out the starter relay. Car cranks over great. Just seems to not want to when the weather is hot.

I believe oldturkey is correct about this being a fuel problem. I had a similar problem with my pickup and the solution I found on another forum was to turn the key on for 10 seconds before trying to start the truck. I haven't had a problem since. Apparently the reason for the delay was to allow the fuel pump to charge the fuel lines before staring-- a procedure apparently required when the engine was hot or in hot weather.

Sorry I must have misunderstood. It turns over but does not start? Check your fuel pump and fuel pump relay and it sounds like you could be loosing fuel pressure. Apparently not an uncommon proble. Here is an excellent link that will help you with the trouble shooting and here is how to trouble shoot your main relay. Good Luck and I hope this helps out.

Here i'm giving a one reason why it happen. Might-be problem occur at main key kit. In internal kit was oxidize. In cool weather the connection is fitted but in hot weather the it's out-fitted. Try service your key's kit in car.

Thanks I will check it out. After messing around with it. When I turn the key on I hear a relay clicking under the hood. the car will turn over great just not wanting to start only when the weather is hot.

Resolder the solder in the main relay which is located on the fusepanel by the gas/brake pedals. They are a common failure in our cars. Reflowing the solder from the cracked/bad solder joints fixes the no start in hot tempatures 9 times out of 10. Hope this helps!

The main relay is basically the fuel pump relay + some other things such as the ecu and other required power items for the car to start/run.

My car will not start when it is hot outside. there is no noise and the car is not attempting to turn over. but in the morning when it is cool it starts and runs just fine. what could this be?
