Hi, my name is ***** ***** lack of power and missfire will be bad injectors, and is common on these, it wont be in the VP44 injection pump, if no codes were set, how many miles do you have on this?
with this mileage, its going to be bad injectors, if the VP44 is new, as for the brakes, these are hydraulically controlled, not vacuum, they have a hydrobbost unit in place of a vacuum booster, you have a bad hydroboost assembly,Tim
was it a P0216 code?
ok, then this isa different story, if it had a code P0216, this is the death code for the injection pump, but the lift pump having low pressure is what causes the injection pump to fail on these, they have removed all the cetane from the diesel fuel , and the VP44 relies on the fuel to cool and lubricate the vp44, if the lift pump gets weak, it will overheat the vp44 causing it to fail, have you checked the lift pump pressure yet?
when he installed the FASS system, did he remove the fuel filter and pump, and run the fass directly to the VP44
ok, first thng to do is check the fuel pressure at the line coming from the FASS, at the VP44, if it does not have at least 11 psi of pressure, then the fass will need to be replaced, but the good news is, the FASS has a lifetime guarantee,Tim
let me know,Tim
