i have a 91 chevy lumina with a 4cyl. that will start but wont run. it has happened a few times but i could leave it for the night and the next morning it would start and run fine, but not this morning. help would be much app.:banghead:

Welcome Aboard!

Starts but won't run? Is the engine cranking (starter operating) but not firing at all, or does it run briefly after cranking then stall?
