Hello everyone. 2013 cascadia 2250 . Yesterday i noticed something weird going on truck shut off twice when parked . I was outside the truck i didn't know the reason for that. So while driving engine shut off and turns back on in the middle of the hwy at night it was scary. All the lights on dashboard goes out and came right back on. No engine light what so ever. i search on YouTube they said its power module the call it PNDB. Or the power switch. I happens 5 times on the road after driving about 300 miles amber light came on with spn 157 fail18. I serach it again on line it has some thing to do with fuel pressure rail. It's true that truck it has less power than normal .i was loaded with 36k lbs on it. So my question is does electrical problem could cause fuel pressure failure . Thx alot Return to Top | find editreplyreplyNext Oldest | Next Newest » new reply Quick Reply
PNDB $311.80 it can give weird codes, loss of electrical power just like you unhooked computer for a second then hooked it back up, and the truck is looking at you going “WTF? Why you keep turning the power switch.” It affected this truck power too, sometimes when power came back it was as if it was pulling 200k.
SPEND SOME TIME UNDER THE TRUCK LOOKING FOR WIRES THAT HAVE RUBED AND ARE SHORTING EACH OTHER OUT, LOOK AT MAIN HOT AND GROUND WIRES LEADING FROM BATT. TO STARTER,MY TRUCK HAD THE SAME THING HAPPENING AND IT WAS A RUB RAW PLACE IN THE MAIN WIRES TO THE STARTER, IT SHUT OFF THEN CAME BACK ON LIKE YOU WERE STARTING IT IN MORNING EVERY TIME sorry about the yelling but key board got drink spill on it?
If you've got the ISX, I wouldn't take that fuel pressure fault lightly. Some years of the ISX had a flawed fuel pump design. When they fail they dump metal right into one of the crankshaft journals. At that point, its usually either drop a new crate engine in or scrap the truck.
