As for fuel pressure I have no way of testing this without a special adapter and gauge.
Back to the main relay... The only way I get the fuel pump to run is by jumping it.. I believe I am not getting a ground from the ECM to the main relay for the fuel pump to run.
I am not sure why. Bad ECM or something else to check?
