** please note i have a very limited knowledge of cars**

I have a 94 civic lx its an automatic. It shows no check engine light.
So my problem begins with it not wanting to start after driving it for a little while. pretty much i get stuck for about ten minutes anywhere i turn my car off.
recently it started to idol rough mostly when i am stopped. i have changed the fuel filter. i have a long list of things i am sure that could be the cause but if anyone can steer me in one direction it will help immensely.

* i was leaning toward the EFI main relay but i can hear the pump kick on i don't know if that makes a difference.

At this point anything will help.
