Need a cummins mechanic

[68Charger]

The dead pedal could actually be the lift or VP44 pump dying- when it throws the p0216 code, it's too late, you need a new VP44 pump.

There is tons of info out there on VP44 lift pump issues... here's a good place to start:

Depending on how much information does he want, there's a ton of info here:

but he doesn't have to spend $4500 on an injection pump (if it needs replacing), a reputable diesel shop can swap it with a rebuilt unit.
if he's on Facebook, have him check out Colorado Diesel Crew page- lots of helpful people there, and good vendors that can help if he needs parts or a shop to take it to.

There are usually other symptoms for the lift pump going tits up (bucking, should show > 5 psi under load) and very seldom is it the direct cause for the VP to fail. As stated the vp44 is lubricated by fuel, if the fuel filter isn't too restrictive, and quality fuel is being used, it'd take a dead lift pump a long time to kill the injection pump. I've had a guy fk the wiring on one and splice the lift pump wiring BACKWARDS! The pump ran...but when polarity is reversed, like many other DC motors, it'll spin the opposite direction. He ran the truck like that for almost 12k mi. Truck still running stronger than ever 5 years later (has a few mods now).

Awesome info guys I'll call him later

FWIW, My hot rod cummins had the death code the VP44. My FASS pump had volume but not pressure. I fixed the fuel pressure issue, cleared the codes and the truck ran great. I had a friend that had the same issue. Once he figured out the low fuel pressure issue, his injection pump ran great, even with the VP44 death code. If he has the funds, steer him towards a good aftermarket lift pump if his injection pump needs to be replaced. It's expensive but if he plans on keeping the truck, it will be worth it.

Minor threadjack if you don't mind.

Last time out towing heavy, my 2004.5 5.9L HO had a few momentary and very minor surges/bucking. I was running the Edge Juice on #2 (tow). Pressure gauge looked good, no loss of power or other noticeable issues. I normally change the fuel filter once/year during one of the oil changes and didn't do it this last time as I only then realized I hadn't re-ordered some after using the last one. I'm even wondering if it wasn't the fuel we got during a fuel stop in Dulce. It was so very minor, almost like uneven road surface during a slight incline. Only happened a couple times not long after that fuel stop and I didn't notice it again after Alamosa.

Fueled up again in Monument and no issues since.

I run "wonder whiz" (PS/MMO) mix in it often to quite the injectors and did so on all fillups this time out. Hadn't run any through in a while prior.

Any thoughts?

I just did a FASS Titanium 150 and Edge Gauge setup for mine (02). Can't risk grenading the good old vp44. I'm about to turn 75k miles on her.

In 2001, the lift pump was removed and an in-tank pump used. If this is the case on your friends, there should be a fuel system mod sticker on the radiator support; the lift pump is on the drivers side mounted to the block near the firewall. I had to change my 2001 in-tank pump as well. It started to cut out after the pump heated up. If it hasn't been changed even with the miles, I would suggest doing so. I went ahead and modified my housing and put a new lift pump on the block. There is a pass through where the block mounted lift pump goes; a lift pump will bolt up in its place. I plan to eventually get a FASS system so I went this route until then. So far my VP44 is working fine after the lift pump install.

Should have bought a duramax!

My co-worker just spent $5,000 on injectors with approx 200,000 miles on his 2001 Duramax. I guess the Duramax injectors required head removal to replace injectors in those years and injector failure was pretty common. The ISB isn't as bullet proof as the 6bt, but I really like the 2nd Gen RAMs for the Dana 60/80 combo under them. There are so many examples of these trucks out there with insane miles on them. I really like mine.

I also did my stack setup in addition to the Edge Juice w/ Attitude. The power difference is insane! It's also quite smokey with the tuner on Level 5...

Funny at the end when the guy on the motorcycle disappeared as his buddy sped off
