So i just replaced the vp 44 and factory lift pump with the air dog 100... i dont think its been on there 2 weeks...the pump no longer gives a priming charge when i turn the key and whenever i bump the starter the pump does not run for 15 or so seconds like its supposed to....heres the kicker the truck cranks up and my fuel pressure gauge is reading 15psi and when i get on the road it holds steady and never drops below 12psi......fuel relay on truck is good...any ideas on where to start?
