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.
Ran before, just alternator was bad so it
didn't run long. Changed crank because it
would take forever to crank.
Do you have the old crank sensor, if so put it back in and try to start. Do you have spark at the plugs?
No spark at the plugs, put old sensor back in and no change.
Possibly a bad ignition mod in the distributor, since you have no spark.
