Details on my truck: 2015 RAM 3500 with 6.7L Cummins 68RFE transmission.
Approximately 135K mileage
Following modifications:
DRD tune with MM3
FLO~PRO exhaust
EGR delete
Loaded the tune to my truck.
It started with no issue.
Installed EGR delete and FLO~PRO exhaust.
Afterward took it out on a drive roughly 7 miles round trip with o issues.
I came back, and at idle, the truck exhibited runaway diesel condition.
I couldn’t stop the engine.
This lasted approximately 30 seconds and engine shutdown (out of fuel).
I drained the oil, and it contained a mixture of diesel and oil.
Roughly 7 gallons total and replaced with fresh oil and filter.
Running my scanner, I am getting 2 codes, 00472 and 0088 (fuel pressure rail too high).
I replaced the fuel control actuator, and the engine will crank but will not idle.
Ray @DRD has been very supportive in answering all my questions.
I’ve also been working with experienced diesel mechanics.
He suggested I reinstall my stock tune and EGR items.
I would prefer not to do this if unnecessary.
Any suggestions would be greatly appreciated.
