This happened to me it was the wiring to the lift pump it Hasidic stopes and made the VP44 try to pull fuel through the dead lift pump. I rewired to the conection and no more problems goodluck

Yeah check for codes, my neighbours did the identical thing. It was a bad injection pump. Sounded like it was missing and such. You might need to prepare to spend a grand on a new pump. Orrrr get a hotrod vp44 from industrial injection and an airdog 150! Haha

sounds to me like yo uhave lousy fuel, and you are getting ice build up in your filters. I one night at about -10* had to duct tape a pile of hand warmers around my airdog to keep the ice melted so that I had fuel pressure. I since found a fuel heater from standyne (35160) it draws 100W and seems to work wonders. it just screws into the plug next to your intake fuel line in your airdog, ie 3/8" npt pipe thread.


oh and by the way, several drive cycles without repeat faults will clear your codes...

One thing that could be helpful is how cold it got. My Air Dog has frozen up so many times, i started carrying spare water seperators. Check your pressure. The sputtering driving down the road happened to me. It happens every now and again and it will only continue to get worse if your problem is what i had. On the injection pump there is an IAT Sensor (Intake Air Temp... i think) that tends to go out...$700 fix Keep an eye on it because it can lead to premature pump failure. f

If you don't have a code reader PM me and you can come over and I'll pull the codes. You must get a fuel pressure gauge!

What IAT costs $700? Sadly your mistaken. The IAT is not on the IP. It's #8 in the pic.
Why don't you start getting your fuel from a better source and drain the Water separator more often? It's cheaper.

Mine will sputter on super cold days with a hard wind and not allowing proper warm up time. my assumption was the temps was causing slight jelling. am i lookin at this right?
