12v p pump issues
 

hey guys so i had a problem with my 12v the mech lift pump was leaking diesel into my oil so i plated it off it has a aftermarket lift pump on it after that it cranked and drove fine for lile 8 miles or so then i shut it down and an hr later cranked it up started driving and everything was normal i got on it a little and the truck started to cut out then the pump made a wierd noise and started to fuel with no control all threw the rpms til gov spring hit. what causes this poor lift pump pressure or p pump going out ? it would fuel for about 10 secs then let out when it would do this any help please!!!

did you check your fuel pressure after the lift pump install? and did the injector pump make this weird noise or the lift pump?
