2001 Holiday Rambler (Cummins ISC330)- No Start Issue
Looking for some help here,
So I went to start my 2001 Holiday Rambler Endeavor with the ISC 330 diesel this past weekend, and it started right up, but after about 45 seconds, the engine shut down and it would not restart. It will crank, but not run.
The fuel filters were changed about 6,000 ago, so I don't think its clogged filters. Fuel tank is reading over 1/2 full. I thought maybe air in the system so I cracked the bleeder nut on fuel line on top of the high pressure fuel pump (down stream of the lift pump) and had my wife crank the engine. NOT a drop of fuel was making it to the HPFP. I then checked for 12v at the Lift Pump.
When holding a volt meter to both the +/- power leads to the Lift Pump coming from the wiring harness, "0" voltage is observed when my wife cranked the engine.
Could a failed Transient Suppressor be the issue? I don't have an engine scanner for the RV, and I am not sure what type scanner to buy/rent; so I cannot see if any codes are present.
BTW, in 2018 I had the Lift Pump replaced at Cummins ($$), and in 2021 the High Pressure Fuel Pump was replaced as that failed ($$$$), so I cannot believe they would have failed this soon.
I'm open to offers for help?
