03-24v/89-12v

My 03 doesn't but my 89 does. ? I hammered out the grounds on the 03, thank you jag1. Now I've moved onto the other woe's this truck is throwing at me. Started with 117 codes got one left and another issue that isn't throwing a code. Fingers crossed.

Well do tell

Did you ever get an answer or figure it out? I'm having the same issues.

Hey guys, so here's my problem. Bought an 03 dodge 2500 24v Cummins. Well I'm chasing it's demons now. Clear the codes and pull new, I get open circuit bank 2 injectors 4-6. I had a misfire on 6 so I replaced the injector (mechanical fail and the injector in it wasn't for the 03-4.5) also replaced the injector harness on #6 since it didn't ohm to spec) still hearing the thump/tick. Second code p2509 I believe, the intermittent power to ecm/pcm. I start checking grounds (I have tested the ecm harness to ecm and harness to b+ and b-, all checked out. So I'm chasing grounds but have had zero luck finding a schematic of grounding wires (have found a ground to cab that was broken) found three grounds on the driver side and nodda on the passenger side. Anywho can anyone help a girl out? Wish it was a 12v I'm tempted to do a swap at this point.
