Scotty, I have a 1994 GMC Sonoma that starts and runs great when cold but cranks and won't start when engine is warm. This Gal needs HELP! I can't afford to pay someone to troubleshoot it and fix.

often they flood out from leaking fuel injectors or fuel pressure regulators. When that old, generally all the plastic fuel injection parts need replacing, they heat up, leak fuel, then won't start when hot.
