i have a 98 gt and it starts fine but when you think it is started an quit craning it it will quit. i think it is a run relay but idont no which one is the run relay i dont have my manual anyone no which one it is. there are 3.

 

Will it run if you give it gas with the gas pedal?If so it could be the IAC valve sticking closed or almost closed.A loose/disconnected vacuum hose will also cause this problem.
