Another vp44 questions
I am new to electronic diesels, so this electronic LP and VP44 stuff is alien to me. On the other hand, I have done quite a bit of injected gas performance work. My questions are; why doesn't the LP run when the key is turned to ignition on like a gas injected system typically does? Wouldn't that ensure there is fuel pressure getting into the vp44 prior to running? I have a Ford Ranger with a vortech supercharger system and a pump on the frame to boost fuel pressure. It kicks on with the ignition to be certain there is plenty of pressure.
I just bought an '01 5 days ago with 50,000 miles, currently getting a new vp44 and a frame mounted aftermarket LP after the dead pedal accompanied by a p0216 death code. This was a real kick in the pants to say the least as I have been looking for cummins power for 2 years. I would appreciate any tips on keeping the VP44 happy.

The way I understand it is you don't want the pump running constantly before a start so you don't pressure lock the VP, It should come on and provide start up pressure, shutdown and then restart after it senses the engine starting/running.
Could I be wrong? (probably).
And as stated, get a fuel pressure gauge, probably one of the top gauges I keep tabs on. I don't not trust lights, especially with the kits that are offered.

IMO if you are replacing the VP I would spend the extra$$ and get an air dog or fass.
As for chips that tap the pump if you have the fuel to support the VP there is nothing wrong with them. The only problem is your tranny that is my problem now. Now my Holley will barley support the fuel I use at WOT it pulls down to 10 psi.
