What if your 1991 lumina turns over but doesn't fire?

Answer 1

Hi thereI got stuck in Germany with my 91 Pontiac grandprix.Similar problem ,had two garages looking the car over after being hauled back to holland , then decided to find out myself.Turned out to be a cracked crankposition sensor. Engine oil creeping into the cracks changes the resistance of the coil in the sensor.You can check this with a multimeter atached, set on ohms.Move a piece of metal in front of the sensors tip and when moving it away again , the resistance should drop off.I got a good used one for �5,- , no more starting trouble.

Good luck.

Answercheck the fuse for the fuel pump AnswerI fixed mine. It was the CRANK SENSOR. It's in a hard to find place; got it from under the car, its in between the oil pan and the trany. At the top of the oil pan in the block on a downward angle. There are two other thinges in the block just above it to the right. (looking from under the car)

My 94 Lumina APV (3.8L) would not start (when warm) - cranked but acted as if no spark or fuel.

Mechanic replaced computer @ $350 (said too many error codes to diagnose problem) - did not resolve problem. Then he replaced the camshaft position sensor (CMP) @ $125 - that solved the problem.
