That is where it all dies. I get no signal out the PCM. If I unplg the PCM and put 12 volts to the green and white wire the fuel pump will turn on. But with the PCM connected and the ignition on I do not get 12 volts at the green and white wire. I have tried a total of 3 PCM's and I dont believe all three are bad for the same reason. But I will double check the fuse under the hood. I know the 30 amp maxi fuse is good, but will double check the other. Is there anything else that tells the PCM to turn on the fuel pump? Maybe some sensor on the engine that could be bad? Like I said, when I apply 12 volts to the control wire, the pump does turn on. Thank You for your responce.
Well come to find out there were 2 PCM fuses and one was missing. Problem solved.
