Hello Guys,
New to the forum. Recently bought a cab swapped 2001 24v 5.9 6 speed with a 15x VP pump. I bought the truck not running and dont really know alot about the mods that have been done to it. It does have an edge tuner and a dual turbo installed as well.
I have replaced the VP44 and still have a no start. I have bled the return line banjo and 1, 3 and 4, to the point of flowing good. I have 20psi coming off the fass lift pump dropping to 10psi while cranking. I do have power and ground at the vp plug. I have also tested continuity and grounds from ECM and PCM.
Replacing the VP44 did change the sound while cranking. Before it was just cranking. Now it seems like it is trying. Looking to be pointed in the right direction. Thanks
