Ok So I reset the APPS voltage and swept it through with the VM on it to check for dead spots, Found nothing. Drove it today and its getting worse, dead pedals like crazy, can't hardly get it to 60 MPH. I took it to a diesel shop but all they did was check the DTC's and told me most likely its the injector pump module. Can these be changed or is there a way to test it? Anybody got any idea if this can be fixed without replacing the VP44?

 

Nope. Nothing inside the pump itself is seriviceable by anyone but a Bosch rebuilder.
Unless someone knows differently?.............

 

I know This sounds nuts but I think I'm gonna trade this truck off for a gas job. It's sucking the life out of me. I Bought it thinking it would be a 500 thousand mile truck and now at 103,000 i'm having so many expensive problems. These cummings engines should be bullit proof, well I guess the engine is but the stuff thats bolted to it isn't.
Anybody want to buy a dodge with a bad injection pump?

 

In a gasser at 100,000 you are started on borrowed time and looking for a new one, in this truck you replace a few things and go the next 100,000.

 

TRUE.
See, that's the issue, replace the $1,000 IP and $150 LP and you're on your way. Get a gasser and run it 100K, 25-50K later your into a complete overhaul at waaaaay more than $1,200.

Maddfoxx, fix the truck. You'll pay more in taxes, tags and title for a new one than the reapair bill anyway. Even though a truck is a depreciating thing, Diesels hold their value so well that maintenance should just be considered part of the overall investment.
What’s a gasser worth at 100K? Take a look on Ebay at Cummins powered trucks, 75% of them are over 100K and worth over $10,000.

 

I do really like the Cummins, I just ordered a pump from Midwest Fuel Injection for $1046.63 free shipping. I'll fix and put in a pressure warning light for the lift pump. Maybe I'll get a spare one too. As a note: The pump tech I talked to at Midwest said that what kills the pump is the lack of lubrication and cavitation of fuel inside the rotor, It makes the diafram slam so hard it damages it. He said it happens quickly and unless you shut down immidately when you lose the lift pump your gonna break it. So beware! a warning light kit is your best insurance against expensive problems! I learned my lesson. Thanks to everyone for the help.

 

I'm gonna do you one last favor here Skip the light idea and get a guage. For $39.95 plus about $10.00 in realted fittings you can know exactally what your fuel pressure is doing. I too wanted a light because I thought I was going to get out of having any gauges at all. The deal with the light is that it is only going to come after you would have already had signs of failure with a gauge. Don't get me wrong it's better than nothing, but seeing real numbers rather than "oops, a red light just came on" is far more comfortable to me.

Take a look at the price of gauges vs. warning lights.

Your right PJ, a guage would be better, I'll look for one. Thanks

 

I'm having the exact same sentiments lately. My truck is currently down, and it looks like VP$$. Thankfully I never traded my '94 chev gasser blazer in, still gettin' me around with 205K miles on the clock. It's there when I need it.

 

Well, I replaced the IJ pump an all is good. $1300 worth of schooling on Dodge fuel systems! Now I know what to do and I will keep my truck. All I need to do is put a locking diff in and I will be happy! This is a great site, I wish I had done more research on Dodge diesels when I bought the truck.
