Truck just died at the lights. Had to tow it to garage, Waiting to hear from them. It made a couple skips just before dying. 93K miles 2011 GMC Duramax. It sounds like no fuel? Ive been watching youtube videos and fuel pump replacement seems like a nightmare. Replace injectors, rails, drain fuel tank along with pump. Is this right. 2011 would be LML right? with CP5 fuel pump? If this is the case what would a job like this cost? Is there any chance it could be something else that just causes the diesel to quit?
