We've gotten a p1689 code on our vp truck. The truck will routinely stumble and sound like it has stumbled then pick back up.
My fuel pressure gauge reads 15psi at idle and 5psi under throttle.
I have only owned this truck since this past summer. The previous owner had put a new vp44 on it right before we bought it. The wiring on the back of the pump looks kinda suspect. Do you think the wiring is what would cause this code ?
