I have no CEL in regard to the injectors, Im running big ass resistors I'll try to take a picture of what I've done with the resistor pack I made. Would running the fuel pump wire to ground hurt the PCM? What exaclty does the White/red wire do, activate a relay or power the pump directly (the latter seems unlikely to me)? If I can trick the comp on that I'll be CELless, YaY!

The red/white wire gets grounded from the ECU to switch on the fuel pump relay. If you want the MS to turn the relay on, just cut the wire at the relay or ECU, and cap the ECU side of the wire off. DO NOT ground the ECU side of the red/white. I'm probably just going to leave that alone, and let the ECU switch on the pump..just one less wire to hook up I guess..
