cummins isl 8.9 died and now wont start?

Failed fuel pressure regulator?

 

I would suggest using QSOL and TS engine cranks but will not start. You could toss parts til the cows come home.

Faults logged upon hook up? 559?

 

No idea what’s wrong with that but, you reminded me of a nightmare I had. I had one of those, when it was brand new, for a year. One of the worst experiences of my life. I can’t even remember everything that went wrong with that ####ing thing. Cummins had some problems with that engine. Half the time they didn’t know what was wrong with it either. All I can tell you is a brand new trucks out of service % was 3 times that of the ‘89 it replaced. In the time I owned it it spent more time at Cummins than working. It’s no longer here. I can’t even imagine what those are like miled up.

 

Next time keep the spray in your box.

Air gets trapped in the common-rail and acts like a cushion that the pump cannot overcome.

Crack the high pressure line from the HP pump to the rail. Loosen the line at the common-rail. The nut has a relief cut in it to the fuel does not spray toward you. Crank the engine until fuel comes out and then retorque the line- Should fire off shortly after.
