the specs we see are 43psi. no, the fuel pump does not run because the relay is not being energized by the ecm, which also feeds the injectors. we can manually run the pump to the 43psi, but the injectors and ignition coils still get no pulse from the ecm. thanks for the reply
So what inputs does the ECM have to have to engage?
