    I just had the valve covers off from my truck and now I have no injector pulse. One of the red wires to inj was nicked so I soldered it. Still nothing. If one of the red or blue
    wires were bad would that kill the other inj green and white wires from operation?

    Did you get everything installed properly? because you may have crimped a wire further back in the harness, also if you hit the ignition module then you may have caused it to stop sending a signal which also tells the ECM to fire the injectors. Also how many miles are on it and have any mods been done??
