Got a good story for you guys. Had a bad ecm that worked on the truck for a week or two, then intermittent no start. Put a loaner ecm and started right up, but had limited peddle as it was a fleet truck and derated. I used that for a few months, and then took it to a Cummins Workshop today to have it flashed back to factory settings. Now, the loaner wont fire, and my family had to drive 5 hours to get two different ones. Now, neither of those will fire also. I am completely confused as to what is going on or what the Cummins company could have did, and my truck is stuck at the Cummins shop. Thanks.

“Before condemning the VP44, verify that you have at least 5 psi lift pump fuel pressure, especially at higher engine loads.” The previous owner claimed he replaced it, and it also has a Fass fuel system on it. How would I test that? I know my way around a gas engine, but new to diesels.

Soon after I bought it, I had the P 0216 code, and didn’t think anything of it because I was unaware of how serious that was. I will check again in the next few days, but could the gradual limited peddle be caused by the vp44 failing?

I am desperate for any help. I have a 1999 Ram 2500 5.9 Cummins, and when I first bought it, it had delayed wait to start. I didn’t know what this meant at the time, but it wouldn’t start at all after a week or two. I put in a loaner ecm and it started up great, and runs okay. Three months later, I’ve rebuilt the original ecm twice, and still nothing. Loaner ecm is still in and working, but seems to have developed some dead pedal. Hot or cold, after 40-50 mph, it only accelerates through the gears slowly after that, even if I mash the pedal. Could it be excessive AC noise killing them? Or two bad ECMS? Awesome truck, but I don’t want to dump thousands of dollars down the drain. any help would be appreciated.
