      Today I found the original fuel pump plugend. It would probably make sense to put that 1 back on the fuel pump/wiring harness? It is the original set up.
      Do you think that other plugend that I put on is maybe screwing up the ECM. It was a plugend for a Chevy sensor.
      I also did self diagnostic test from ECM today I tested in Mode 2 code 31 -ECM, Mode 3 code 41 Air Temp. Sensor.
      If there is anyone out there with any suggestions…love to hear them.

        Put the nissan plug ends back on. Do you have a wiring
        diagram you could post? When the key is turned on the pump
        should prime. check your power to the pump. should be 12 volts dc

          I have power 2 fuel pump and it is hard wired so it is always on. When you pour gas down throttlebody it starts then dies. I went and got a use ECU and that didntwork… when u do self diagnostic in mode 2 green lite stayed on no flashing no red flashing, then mode 3 code 41 is the only 1 coming up.
          I also didnt find original plug end for fuel pump. I thought I had…Bummer
          Thanks for replying greatly appreciated.
