He is right. Missed that with 2lb. That low may be your issue and or the cause of bad VP44's
Curious, was the original lift pump that you replaced on the block? Or did it have the retofit where Dodge put it in the tank?
Good thought, Maxwedge. If the external pump (on the block) is added along with a failed in-tank pump, this is exactly what kind of fuel pressures I would expect. It's very difficult to get much flow through a non-working positive-displacement pump. Some pressure would show at the on-block pump output, but any load on the pump (engine starts) would drop the output way down because of the restriction of the in-tank pump.
SOOOOOO I was trying to diagnose why my genesis trailer brake controller flashes OC every time I turn it in for a few minutes before it quits. And I seen this green wire. I was like huh what’s that for. Come to find out there is a black wire hooked to the drivers side negative terminal. So I decided to follow those wires. They both go to the top of the tank with wire nuts right at the tank. I am going to fix this. But I decided to hook the green wire up to the battery. And boom I heard a humming sound from the tank. So I jumped in the truck and it took it a few seconds to start(head pressure from hard wired pump) took it down the road and she drives like a dream. Seems to be low on power but that cooks just be me used to a trick with 150s and 4.11 and a truck with 6x13 And big turbo. So Iwas trying to suck a softball through a straw. Anyway to hook up this in-tank pump to the factory wiring harness and have both running. Might help fuel pressure? Is the factory fuel pump plug power and ground or power and signal and it grounds to the engine? NO MORE P0216 code
