We had very heavy rain a month or so ago and the next day I went to go start my 1986 600es 2.2 turbo. The gauge lights flickered on and off and went haywire, along with the Power Module made a very loud noise. I figured the PM was the issue so I bought one from another member on here. When I went to replace the PM with the new used one the issue stopped with he lights and noise BUT now the fuel Pump doesnt get power, or prime when the key is on. I put 12vs from the battery to the Negative side of the coil and the pump runs. I went to go turn the car over while doing this it still doesnt run, i havnt checked spark but I am thinking my New used PM is bad. Are there any Fusable links or anything else I need to try before buying another PM?
Thanks for the input,
