VP44 died when the wife and kids were driving through the San Joaquin valley at 104 degrees. She was passing a semi during a long trip to Montana. OBDII: P1688, controller failure, 80K mi.

Even though I performed preventative maintenance by the book, a controller failure just shows more design inadequacies for the VP44.

I think I was disheartened more than anything becuase that truck ran flawlessly and was very reliable up to that point. That is up to the point of abondaning the wife and kids in a bad part of the freeway in the heat of the day.

Bought and installed a rebuilt injector pump from Midwest diesel with new lift and filter. No further anomalies to date. Additionally, installed BD Aux pump, fuel pressure gauge, and 4" exhaust.

 

welcome to the site! I wish I had good news for you, but your vp44 (injector pump) has died on you. I see that you bought a new one did that get you up and running agian?

 

Yes. It runs good as new minus normal wear and tear due to the garage and the kids’ bicycles. Now I'm hooked on horsepower knowing that warranty has expired on the powertrain.

Apparently, everyone is on to the fact that diesel has higher theoretical work from higher compression. Now that electronic control can easily modify timing and fuel flow, the aftermarketeering people see the associated profits to be made. I’m seeing now a lot of R&D into aftermarket diesel technology now as opposed to 10 years ago.

I've been reading though that the VP44 is limiting to around 600HP+ power range. I’ll try and bump over the 300HP mark first, then continue on from there. It will be like owning a new truck again. Only faster, having the same scratches, and costing three times the money.
