Just curious here. The VP44, is it engine driven, electronically timed right? What I mean to say is that the fuel is pressurized by the engine driven gear and the electronic stuff open the solenoids to realease a shot to the injector? If someone could tell me how this thing work, I would appreciate it.

 

jrs,

Here are some links about the vp44, don't know if they anwer all of your questions.

The Blue Chip article states that a weak/bad lift pump is not the cause of VP44 failure. My truck will not run above idle w/out the lift pumpkeeping atleast 1 psi to the Vp44. Makes me wonder whether the rotary pump in my VP44 is bad.

 

HOTDRAM, that 2nd link gave me what I needed. Thanks.

 

Good deal jrs.

In another post, you mentioned you worked on electronics for the Coast Guard in Guam. Do you work on radars or radios or computers etc. etc. etc.
