Is it at the back of the fuel bowl? I’m not sure I know what harness you’re talking about. I do think it would be something in that area tho because I just cleaned it and now it won’t start

Okay just went out to the truck and found the harness for it it connects right by the GPR and has the fuel bowl heater wire and ipr wires on it. Looks pretty old and untouched. Should I order a harness?

More testing today. Couldn’t get any good cranking dat cause battery’s were too low but I got this new code so I believe I might have hurt one of the wires. Second pic will be koeo ICP volts and duty cycle

Found this today taking the fuel bowl wire harness apart. I’m guessing this could cause my code correct? The wires are clean and not touching other wires but could diesel or oil on them cause my short? Got a new wire harness coming I was just gonna delete it and use the ipr wires but in the Colorado winters it’ll get to like 10-20 degrees some mornings so I figured I’d just get the harness

Well thought I’d post this if anyone has a similar future problem. Got the new fuel bowl harness today finally and put it in. Fired right up. Thanks to hit man X for the idea
