Hey Everyone, I noticed reciently that my lift pump is not coming on before I start my truck. I turn the key to the on position and no pressure from the lift pump. When I do start the truck my fuel pressure is 13-15psi drops to about 9-11psi wot. I know it isnt normal for it to do this, could it be a loose connection or you think it is the lift pump? Its a stock lift pump from Cummins Dealer I put it on about 6months ago. Thanks Corey
