Isx 15 will not start

[CumminsFreak]

Im just west of Chicago, checked the fuses in front of the cab, inside and by the battery, it seems to be in order. I have insite and I will hook it up tomorrow and do some more tests, and well first thing that came to my mind when it didnt want to start was the fuel pump, so we took it apart and indeed the plunger was stuck which could be a reason it didnt start, got new plungers and rollers, putted it all together and still nothing. Truck seems to start and just dies after few seconds, low pressure fuel pump turns on, I will need to find my compucheck fitting somewhere and see the pressure. I really wonder if theres some low voltage protection on Kenworth, because before that truck was running flawlessly.
