matador,
For future reference, I have had trouble with the relay that controls the solenoid. It is located at the top of the firewall, above the motor. There are two there, the on that controls the fuel is the on on the "driver" side. A good way to know if it is the relay is if the motor spins over and wont start, leave the key to "on" and push the plunger up with your finger, then crank. This will make the fuel start. The only problem is if you stop the engine, you will have to repete the process to get the engine started. I think the relay is about $47.00, and just unplugs. Also if you have to replace the solenoid, alot of parts on the Cummins are interchangable with a 7140 Case IH Tractor. Tractor parts are sometimes cheaper. I am running a tractor solenoid and camshaft fuel pump. Hope this helps..Case IH $124.11 for sol.

Thank you very much for your reply! I kind of thought so too, but being this is the first time I took this thing apart and fairly new to diesel ownership I wasnt 100%positive.
Thanks again,

Hey guys excuse me for butting in, but do you know what would happen if the rubber boot on the solenoid fell apart. mine is getting pretty bad. The rubber is all crumbly, and has holes in it. I tried to adjust the solenoid shaft to 2 & 5/8 inches like it said on foster truck, and noticed the boot was in bad shape. Im having starting issues, and losing power, and was wondering if the rubber boot had any affect on that kind of stuff. Anyway do you guys know?

My boot is bad too just like yours. Unless the metel part that hooks to the fuel shutoff arm should come out of its snapring which is part of the long metel rod with the spring around it. Which it is not supposed to do. You shouldnt lose anything. However if it was like mine where it got so lose if came out of it then yes you could lose stuff. I fixed mine so it wont happen anymore. I am keeping my rubber boot for a while the way it is. They do sell them for around 25 bucks however.

Thanks Banks Powered,
I will keep that in mind for future reference.

Guys, Ive heard that you can repair the boot with rubber from a bicycle tube and a couple of cable ties. Worth a shot, and a CHEAP fix if it works.

Yah, I have more time than I do money, Thanks Dr.

I can definitely tell you that the rubber boot can be replaced with a bicycle tire tube and wire ties as I just did it a week or so back. I found you need a tube that is for 24" bikes as they're fatter than 26" bike tires (the type often refered to as racingor road bike tires). I found a fairly cheap tube at Wal-Mart for $2.56 as I recall. You'll also need to use 4" wire ties; use two together to make it around the large end of the solenoid and one on the smaller end. Works like a champ. I think I got this from a post on this topic by Infidel - gotta give credit where credit's due.

Good info, thanks.

matador

That is good to know. Mine is almost falling apart but I put it back like that anyway. When it actually does I will do the bike tube method.
