Nothing.

Replaced the buggered fuel line to the injection pump with new parts from Cummins. Bled the line at the filter/separator, made sure it was full, primed the transfer pump. Connections to the shutoff solenoid are clean and tight. Zero.

Is there an inline fuse for the shutoff solenoid?

Tomorrow I'll replace the fuel line from the tank to the transfer pump and the return line to the tank.

Ideas?

I'm dangerously close to having it towed the 45 miles to the Cummins shops since as of today I've found no one in Raleigh who will work on it.

Are you getting fuel when you crack the injector lines?

If not: Have you checked for power at the shutoff solenoid? If you have power there but still no fuel out the lines, you can remove the solenoid, pull the plunger and spring out, then put it back on to eliminate that possibility. If it starts, use the manual lever for shutdown.

Do you still have my cell #?

Denis

Hi Dave,
Haven't cracked the injector lines yet. Been putting that off 'til last. Haven't checked for power at the solenoid either.
I'm not sure where I put your cell. Could you PM me that and I'll call you tomorrow? Thanks!
Is there supposed to be a spring connecting the manual shutdown to the bracket behind it and keeping it pulled to the back of the truck?

wannadiesel

No, but it's spring loaded so it stays back. IIRC, it's kind of wrapped around the shaft?

Denis, I think that's the problem right there, I changed the fuel filters on mine when I first got it, primed everything but didn't crack the injectors. Couldn't get it going for the life of me until I cracked the injectors. Started right up once I did that. Hope this helps.

It is VERY common to find the fuel shut-off solenoid as the source of the problem.
It has two wires attached to it (spade connectors) pull them loose and really check out the condition of the connectors and the spade blades on the solenoid.
It doesn't matter which wire goes on which blade. One is to trigger the solenoid and the other is to maintain the solenoid in the run condition.

Okay, Spitzair and Dave, this afternoon I'll crack the injectors. Is it necessary to do all of them?

Usually if you can get fuel to 2-4 of them, it will take off. It will run rough for a little bit, but should smooth out as the air bleeds out of the remaining lines

I usually crack 3, every other one. Crank it on and off quick. Retighten. Crack the other 3, quick on and off and retighten. Then fire it right up. It may sputter, just do them again one at a time while running. You'll get to know the truck better as she begins to purr again.

You may find you have to repeat this cycle a couple times to actually get it to fire. As long as you're getting fuel it will fire, just keep cracking and cranking. Crank for at least 10 seconds a shot, just bumping the starter won't do it.
