the fan motor could just be bad, you can test this by removing the fan and connecting a wire to each terminal and to a battery. the wires hooked up one way will spin the fan and the other way will spin the fan backwards so you cant hook it up wrong. I hope that helps you out!

Same problem. 1995 Pontiac Grand Prix V6 3.1L no start problem Question The problem, my car runs great first start of the day but does have a miss fire, and I can drive for hours without a problem, but when I turn it off and try to start again 30 -60 minutes later it chuggles and dies and won't start for a least 3-5 hours later, then runs fine again. It trys to turn over and the battery does not drag, no signs of a bad alternator. Everything has power, all fuses are ok I checked them today. Second trip to repair shop resulted in no 3 fuel injector replaced with good results. Fuel pressure checked out ok, No smoking white or black, fuel filter replace and car had a tune up recently also the mass air flow was replaced supposedly, I am starting to wonder if these parts were actually new used or not put in at all but I am charged anyway this is fourth time to the repair shop however now the third time but this is at no charge by a church member's friend so I am inclined to take his advice and think it is the engine module. Three different auto repair garages tell me the following: either the cam shaft sensor, crank shaft sensor, or ignition module, causing no start or start and chuggle and die problem and bad & loose hoses sucking in air. (From my experience engines don't take in air they leak it out through vacuum leaks.) Apparently the last fix resulted in hand made manifold gaskets I did not know about and may also be causing contamination on my low coolant sensor cause it stays on, however back to the no start problem; my engine is getting to much air I am told, I am incline to think there is a vacuum hose leak somewhere instead. Was also told intake manifold gaskets may have a air leak, bad and loose hoses and possibly the sensor's I mentioned. So before I shove out money I don't have, I am doing some homework and found your site. What do you think is going on. Someone else said I do not have a crank shaft sensor. So I don't know whom to believe.

probably not a relay,check the coolant temp sensor to make sue its reading ok,if its misreading it will not tell the computer to turn the fan on
