Okay guys I was having hard starts and I was going to start by getting myself a AirDog Raptor 100gph lift pump, I bought it today and put it on. The truck started right up I mean right up. I turned her off a couple times waited about 10 minutes and it fired right up again. I mean its never started that good besides in the mornings. Anyways I went inside all excited and what not and went back out to go drive around, I startedcranking her over, it just kept cranking and cranking i actully quit, say the f word a couple times and tried again. She started the second time. Now I'm not sure if there may have been a little bit of air in the system still? Or if I have a air leak somewhere I am STILL missing, or the VP44 has thrown a fit and decided to peace out. One last thing this is my main concern right now, Does anyone know the stock PSI setting on the Raptor 100 pumps? It is adjustable, I couldnt afford the fuel pressure gauge today so I am kind of screwed on that. So if anyone has any idea what they come stock at? I mean I am guessing it would be the normal 15-18psi right? Idk throw me some comments please. Help me out, this is a real PITA.

 

Yeah I think they are set at 15-16psi from pureflow. Your new pump may be too little too late, but you need a fuel pressure gauge as you already know. Do key trick see what codes you have, if any.

 

P0122 and P1062 or whatever it is the companion code.

Could it be that overflow valve? I may just go buy the one a guy has in town at a local shop hell sell it to me for 20 and if it doesnt work I guess its the pump.

 

I wouldn't just go throwing parts at it. Are you sure about 1062? I do know 0122 is APPS voltage. You had lift pump on the block before, right?

Companion code is 1693 is that what you meant?

 

Yes and yes the stock one was on the block

The VP44 is dead, I just left my girlfriends house only way I could get the truck started was I had to shower the pump with cold water for about 10 minutes.. im pissed.
