2001 GMC Truck Repair Question
GMC 1500 HD electrical problem
Why do you have to jump it, is battery down? Have the battery and charging system tested. Any applicable trouble codes?
It could be any one of several things, intermittent rpm signal, maybe the ignition switch has a problem? You have to test when problem is ongoing.
