If any one knows anything about P7100 pumps I need help. I just got a '93 that someone has put a p pump in. I have no no way of knowing if it was put in right. The truck starts fine, runs fine then dies just like I cut the fuel. It already had a mechanical fuel shutoff instead of the celenoid. If I let it sit a minute it starts right back up. I think I can hear a "reset" click inside the pump after it dies but I AM LOST! Any help would be great thanks guys
