Next, check for spark. If you have spark and fuel run a compression test. If all cylinders test low or zero, it's jumped timing. HTH. -Jim

To check for spark, remove one of the spark plug wires from the spark plug. Insert a large screwdriver with either a plastic or wooden handle into the end of the wire that plugs on to the spark plug. Hold the metal part of the screwdriver close to something metal that's not painted on the engine. The exhaust manifold is good for this. Now have a helper crank the engine. You should see and hear a good strong spark jump from the screwdriver. It'll sound like SNAP-SNAP-SNAP. HTH. -Jim

Just changed alternator and crank sensor in my 1998 Chevy tahoe, now truck just turns over, pumps is fine, fuses are fine, throttle position is fine and map sensor is fine, truck ran before. 3 answers
Ran before, just alternator was bad so it didn't run long. Changed crank because it would take forever to crank.
