    Default Fuel pump

    After a long restoration, today it was time for the first engine turn-on.
    I put the key, switched it on and i heard the usual "bzzzzzzz" of the fuel pump... i also heard the "click" from the relay BUT (here's the BUT) the pump was still doing "bzzzzzz".
    Usually after few seconds it should stop, and for sure last time i used the bike it was working normally...

    Any idea? I hate electric problems... uffffffffffff

    Did you mess with the eprom in the computer? Is it installed the proper way? Clean the relay terminals also. I had a bad/damaged eprom that did this intermittently. If not that, it could be a bad ecu.

    I've cleaned the relay... and i hear the click.. but it seems that nothing happens.

    I did not touch anything in the original computer and all other stuff! I'm too bad with electronic things...

    I had this when I had the wires reversed. Was the wiring and connectors played with during the restoration?
