Check the engine harness from the Crankshaft position sensor and around the AC compressor to the engine harness. Make sure no oil is in the connector and that the harness is not rubbing the AC pulley and is clipped to the compressor mounting bolts. Also make sure the crankshaft position sensor is intact. You will have to unbolt the AC compressor and slide it aside. You do not have to disconnect the AC lines or completely remove the compressor.

Do we need to jack the truck up to get to the bolts to get this done?
Expert:  A. Penland replied 2 years ago.
Yes, to unbolt the compressor. But not to inspect the wiring and wiring connector to the crankshaft sensor.
