Question about 1993 Chevrolet Lumina
I have a 93 chevy lumina euro 3.1 liter. it will start and run fine until it warms up. once it gets warm it seems to starve for fuel and dies! no matter how i try to keep it running it will die anyway. if i try to start it right after it dies it fails to do so. if i let it sit for 10-15 minutes it will then start and run like nothing is wrong wiuth it...until it warms up again! can you please help me??!!!
Sounds like it could be a fuel injector shorting out. have to get it hot, pull off the plenum and check the resistance in each injector. if any injector has bad resistance, replace it. when an injector shorts out on these particular vehicles, it shorts out the whole injection circuit. and when it cools off the resistance goes back up and it will run ok. i think the correct resistance should be about 13 ohms.

I have same problem and i will say this that it happened when the car ran out of gas. so i assume it is the fuel pump i already changed the filter and that made no difference. im going to drop the tank and change the fuel pum within the next couple weeks so i will definitely post the outcome 4 everyone. ps a good friend of mine had a lumina of same type and it acted the same but it would NEVER start. he changed the pump and it was fine after that. ill post soon

My 93 lumina euro starts and runs fine for about 10 to 15 minutes and begins to spit n sputter then it will stall if your not on the gas. Even sometimes when u put it into drive it will just stall.... but it always starts right back up and continues to do this problem untill it cools down some. I checked the spark plug wires and all three up front were arcing which i doubt helps but i was also told that the wires arcing is probably not the only problem. The other problem i was told it could be is the mass air flow thing in the intake tube..... any one with any suggestions please share
