Truck quit
My 90 Cummins truck just quit the other morning going to work. It just shut off and would not restart.. I changed the fuel filter and still nothing.. I bought a new lift pump and put on it, and waiting for the battery to charge to try it again.. It did fire on starting fluid .. What could be the problem if its not the fuel pump ?

^^^^ what he said.
Wouldn't help to change the shut off solenoid if a fusible link or ignition switch, or even just a loose connection is keeping it from getting power.
The most common problem with the fuel solenoid is the quick disconnect terminal on it quick disconnects.

I have even rigged up a wire that clips to the FSS and has a alligator clamp on the other end for the positive battery post.
I hook it up, then start the truck, you pull it when your done.
The truck was a parts / yard plow and the wiring had been HACKED by the PO.
If you ran a quick wire to the FSS and it starts, you know you have a good FSS and it is in the wiring somewhere.

From the sticky, where you will find pretty much everything you need to know about these old trucks. Saves us from explaining this to 1000 different people every month.
