Hey guys, I have a 2019 F250 6.7. Was getting some low fuel pressure codes blah blah blah changed a couple things out and also changed out the fuel control valve on top of the cp4 and also to check to make sure I didn't have no Glitter. Everything was clear and clean as could be but after I put it all back together it wouldn't start. Low/slow cranking.
I'm getting fuel to the hpfp but no pressure in the rail. The electrical connector for the fuel control valve is only getting 3.4 volts of power with key on. I'm decent at turning wrenches and part swaps etc but electrical hurts my brain! Can anyone explain or point me in the right direction and tell me in the simplest possible way of word to even begin to figure out where the power issue is if that's what nothing it is. Thank you
