Hey guys anymore knowledge on this? I'm having the same problem. My truck starts cutting out/sputtering/bucking and white smoke. I changed the lift pump and this problem started up 4 days after it was back on the road

I had dead peddle when it was cold changed vp life is good

I just got a new vp and raptor supply pump installed and she runs like a dream now! It sure hurts your bank account willyt, but if feels good to get her goin down the road again!:jump:
