2014 Cummins ISX15 won't stay running opinions please

Hi gang!

Miss E here. We just bought a Kenworth T680. Ran it to Dallas/FW and back two days ago. Had been throwing water in fuel code, so when we got it back we planned on changing the separator and main fuel filter.

Before we got a chance, it refused to start. Turn the key - starter cranks - truck fires up and runs for 3 seconds up to about 500 RPM, then sputters and dies. Seems like not getting fuel. SO... we changed out the separator. Tried to crank it and bleed the lines at the maintenance point in the rail right next to the pump. Bled out the air, spewing diesel, cranking 2-3 minutes. no dice.

So then we changed the inline. Bled it through and again, no dice. It acts the very same as if we did nothing at all. Cranks, starts, starves and dies. Pump is getting power, you can hear it run. The fuel rails have pressure to the maintenance plugs.

Help help? Any ideas? Me and Mr. E are stumped.

 

Thanks, gentlemen. Yeah we did everything we could. Had her towed today with a suspected waist gate valve issue after hashing it out with the service manager.

 

I know I didn't want to drag it in. Yep, they can be crooks. But we're not tooled out enough to do everything just yet.

So, they're crooks with tools. lol
