I have a '98 3.0 Ranger with perhaps 300,000 miles on it. Not sure as odometer motor is bad and is stuck at 199,000 and hasn't worked since I bought it. I am wondering what fuel pressure should be ? I have found 30-40 psi and others say the 98's should have 55 psi. Mine is suffering from low power and poor starting. Sometimes starts about like a flooded carb engine or starving for fuel perhaps. With the high miles I suspected injectors so I put them in tonight and I THINK it may have more power I'm not for sure. Seemed to start fine but will see in the morning for sure.
I am chasing the left and right bank lean codes. My fuel pressure is 39 psi at 2500 rpm. drops pretty quick when you shut off engine. Wondering if this is in spec or low. Replaced fuel filter a while back and it only has 1 inlet and 1 outlet IIRC.
I was going to put on a new FPR when I did injectors and ordered this one

Looks different from the one on this truck. Mine is at the front of right fuel rail and is much smaller with a vacuum line attached to it if I am looking at the right thing. I did not take it off to see if the new one would mount up anyway.
I have no idea how old the fuel pump is or if it is the original but if I am supposed to have 55psi I am leaning toward a weak pump.
Any help appreciated.
