    I haven't probed the ecu to check for power yet because i don't know which ones are supposed to be 12v+(i can't find my dam ef tech-book!!). But it is getting some kind of power if I jump 12v+ to the trigger terminal on the main relay because the red led in the ecu lights for about 2 seconds and I regain spark but no 12v+ to the injectors(I checked before and after the resistor pack) nor do the injectors get grounded out by the ecu and still no power to the fuel pump...so no power or pulse to the injectors. I checked my noid light on my car to make sure it was working & it is fine.
    I double and triple and quadruple checked all of the wires that i ran(2 for injector #2 & #4 and 2 more for the crank angle sensor) into the engine bay and all of my connections on the ecu harness. Everything is soldered and heat shrinked.
    I have done a decent amount of wiring before, but this thing.....man it has got me lost.

    have you rechecked your dpfi to mpfi wiring? im not sure if your post is a little vague about it, or if you wired the crank angle sensor wires improperly.

    do the injectors have power or are they getting a pulsed ground signal?
