Well today I played with the relays in the truck the asd and I got it to fire up but then I died after a min and very rough idle I have a fpcm coming tomorrow just to rule out that it’s that. After playing with the relays I started to hear the pump run then turn off without the truck started...
I jumped the pump with my tester it works. I checked the voltage it shows then drops. When I plug the pump back in and cycle the ignition I don’t hear the pump running and no fuel to the rails. I did get a code for
U0109 Lost Communication With Fuel Pump Control Module.
P0463 Fuel Level...
Good evening all.
I have a 2018 ram 1500 v8 it has 70k miles on it. Long story short went to home depot got material auto started the truck while loading it the truck died. I crank it and it won’t start. I get it towed back to the house and narrow it down to a fuel pump I just replaced it today...
