Our 04 V6 has very high fuel pressure and we can’t seem to figure out what’s going on. Car has a new fuel pump and module assembly installed by the previous owner. I replaced the spark plugs, plug wires and fuel filter as part routine maintenance. Fuel pressure on cold start up is ~39 psi. Fuel pressure increases after car has been running for a while. Also seems to increase when off the throttle. Tonight fuel pressure was still high(~57psi) even when accelerating on the highway at 55mph. Measuring fuel pressure both electronically with my BlueDriver OBD2 scanner and it’s roughly the same as with a mechanical gauge(at the time was around 55psi). I dropped the tank today and found no open or damaged wires at/in the tank. Any help would be greatly appreciated! There are no codes.
