Amongst all the belief, the VP44 can fail from other reasons besides not enough fuel. Apparently the computer that sits on top of the VP has soldered electronics where by Bosch used a type of solder that is affected by heat. Heat causes the solder to break down and deteriorate which causes the computers connections to fail. Once this begins to happen your truck can have hard starting issues, white smoke exhaust, or shut down at any time like you turned off the key. The only thing that determines how long it takes for this to happen is whats called heat cycles. Basically the more times you start and stop your engine over the life of your truck. I dont know if warmer weather plays a part but I'd imagine it does. I actually had my VP fail about 6 months ago and I cant believe how many post I've read lately where this exact problem is happening to others. Thats a clear indication that we all tend to suffer from the same problem at similar times as our truck age.
This doesnt mean thats whats wrong with your truck but if you determine that your LP is working fine and you have no other codes telling you otherwise then
If you need a new VP then make for sure that you get a FULLY updated and FULLY rebuilt pump.
