My 2001 dodge 2500 24v 5.9l cummins gave me a no bus code yesterday started out with the starter sticking on after start put a new starter on and that was fixed but still had no bus I checked connectors and fuses all was good still no bus I pulled the run ignition and acc fuse and put it back in and the truck ran again drove it home and on my way to school today lost bud again pulled the same fuse and it came back for a second then lost again I need help badly anything helps thanks

 

One of your sensors is failing. Trouble is, it could be ANY of them, and there are a LOT of 'em.......

 

so how would I know which one start unplugging then one at a time like unplug and see if bus is back and if it’s not plug it back in and unplug another

 

Yep. Tedious, but, it usually works.
