    Fuel pump woes

    A co-worker of mine has an 07' street bob that been sitting for about 8 months. He put a new battery in and now when he turns on the ignition switch the fuel pump does not come on for the 3 second fuel system pressurization. we disconnected the fuel pump and jumpered it to the battery and it works fine. Other than checking grounds I'm at a loss.

    Also look for a relay when testing the fuse. Remove the relay and test for power to it, sometimes just removing the relay and installing back in will make a good connection.

    Ok I was wrong. He has an 08' with a super tuner. Checked and cleaned all grounds and replaced all fuses. Relay is next. After that it's off to the Stealer. on a side note he just informed that his head light (known good bulb) doesn't work.
