    No fuel ECU hums

    I recently did a head job on my m20b25 that showed me the fact that some asshole had cut the connector off of the fuel injector harness and crimped it to the main harness. I tried to patch this when I put it back together but the car wouldn't start.

    I replaced the harness with a known good one from a forum member and the car still will not start. I am getting no fuel. I've tried two fuel pump relays and no luck. I have also switched both of my fuel pumps (325e chassis) with known good ones from forum members. Also my ECU is humming. I don't know if it is suppose to do this but I don't like it. I'm afraid I may have killed my ecu when I wired the fuel injector line back together.

    Anyone have any ideas?

    Do you have spark when cranking the engine? No spark means no timing data to the DME or that the DME isn't running or good and that means that the fuel pump(s) won't run.
    The car makes it possible, but the driver makes it happen.

      I'll check that.
