Main fuel pump (#1) runs but shows no pressure. Aux. (#2) runs and shows pressure just fine. Thought it was a bad pump so I sent the whole assembly to Lockwood and thought they would test both and confirm that main pump was bad but they just sent me a replacement assembly.
Put it back in and still have the same issue. Pump # 1 runs but never develops any pressure. Pump # 2 works just fine. Shows 43psi.
Used a volt meter to check the voltage on the power connections and both show 13.1 volts. This is when not connected to the pumps.
Swapped power leads and with the power lead for #2 connected to pump #1 it works just fine and shows pressure as it should. Pump # 2 now just runs and never builds any pressure.
What am I missing?
