Does your commander turn on when you try to start the car? I tracked mine down to the PowerFC being the problem. (assuming this is s13-s13sr) On your harness there should be an ECCS wire (black/red wire iirc). I think it's pin 5 or so(check your diagram). Strip away a piece of the sheilding so that just the bare wire is exposed. Take a 3' piece of wire, twist it around the ECCS wire, and ground it to your chassis. Does your fuel pump turn on? Commander? If so, your PowerFC isn't doing what it's supposed to do. You can wire in a gound switch from the ECCS, and turn it on before you start your car. Or buy a new PowerFC.
