Hello I own a GMC 2001 Jimmy I recently tuned up this vehicle changed the fuel pump and filter as we'll as transfer case. The truck still gives me a sluggish rough drive when driven above fifty mph or****** as if loosing power please give a brief diagnoses of this vehicle problem asap. I've read something to the affect that this car has a passlock code or a pemlum switch in which I may have to take it back to the dealer in order to have the truck driven normal again? Is this true? You can also email me at 1blackman80@gmail. Com, if you have great information that can help me, I work 2 jobs and I definitely need this truck fixed asap im so exhausted. Thank you so much.
Mr. A. Darden

Passlock has nothing to do with the way it drives. I suggest scanning the computer for stored codes and analyze the sensor data.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
