    i need help

    ok,
    i now have 2 ecus here with me, neither will start the car

    i have performed a few tests
    the main relay works perfectly
    if i disconnect the computer jump #36 and #2 then ground #3 the fuel pump runs therefore all of the wiring that is not in the computer is working perfectly.

    i tested to see if im getting good power and ground to the computer which i am

    im getting a good ignition switch signal at the computer.

    what is going on here, is there a way to check the computers to make sure theyre working correctly?
    if i blew both of them what could cause it?
    i just put in 19#ers i dont know the impedance how could i find out?

    edit: i also did a manual check to see that the injectors where wired in right (similar to what i did for the fuel pump)

      Crank position sensor? OBC relay box stuck?

          No spark and no fuel almost always points to Crank Position Sensor.

            This may sound kinda noobish, but do you have a twelve button obc?

                So the obc isn't reading code while you are trying to start the car is it?

                  nope, crank sensor fixed the maj of problems, now i get no fuel pressure, fuel pump buzzs but doesnt seem to pump anything, could i have the fuel pump wires on backwards or will it only run one way. (the plastic connector deal came apart in my hands last year when i did the engine swap so now i just have to shove the wires on idividually)
                  give me some ideas i want to drive my damn car

                      Did you check the wires on your fuel pump??? Sometimes they are on backwards!
