Ok so I put a new vp44 injection pump on the truck thinking that was the problem. But it wasn't I turned the truck over and over and wouldnt crank. I unplugged the rear plug on the pump and straight wired the pump and cranked right up. Then I checked the plug pin # 6 and 7 gets 12 volts on the on position and 10 on the starting position. Pin # 5 doesn't have any voltage so it's not that. Anyone know what or why the electronics won't work and allow the truck to crank? Thanks.
