Had to rerun wires to fuse panel box basically replacing the back wall of the fuse box
The dash lights work It’s just the start up and I know the jakes brakes, cruise control and manual fan does not come on
I replaced batteries to and double check all connections on battery side and fuse box by batteries
I have a 2009 kw Cummins isx I replaced the gear lift pump, transfer pump, new remand Ecm and re did all the fuses and relay, the truck turns over...
Still doing it after I open fuel caps
Ok I will
It’s crazy because I can fill both tanks and the rough idle goes away for a bit
So is the fuel pump and transfer pump different
Hopefully that’s it any thing other than the fuel pump the transfer pump is working can hear when you turn the key over
I change the fuel filters already
I have a 08 kw 900 with the Cummins isx en#79300625 the engine light came on and it’s says fuel delivery pressure mechanic says it the anti drain...
