    m50 relay the white one

    wont stop buzzing like crazy. its buzing like crazy and vibrating. more than it should.

    i was trying to jump start my m50 car and the posi jumper cable touched the ecu.

    do you think i fried my ecu?

    idk why its not working. i tried a different white relay and it did the same thing.

    the white relay controls the fuel injection and im not getting any fuel.

                Could be. When you switch on IGN it powers the relay which sends power to numerous things, the fuel pump relay included. I jumped it initially when I had a no start on my second swap. It was the problem. I'm not sure why it's buzzing though. That means it is being turned on and off super fast basically. DME could be pooped.

                  ya i think the DME is sending it incorrect power or something. i need a dme to test it though QQ need to go buy one nwo
