I have a 1994 GMC Suburban and once it is warm and is shut off it wont restart. I have replaced the coil and the problem remains.

Do you

When the problem occurs, have a helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Any applicable mil codes? Do you have the spider fuel system?

I don't think that it is a spider fuel system. It is throddle body. I did notice this time that I got it running that the service engine light is now on. I will get the pressure gage from a freind and check it too.
