Title: '04 M800 not starting - fuel issue?
Post by: Christian on May 16, 2017, 05:22:33 PM
Hey folks,

Rolled my M800 out for a spring ride and she won't start.

Bike turns over - battery voltage was low at first but a few hours on the charger brought it up.

I realized I didn't hear the fuel pump priming after a bit of not starting.

I can hear the relay clicking when I turn the key. I did swap them to see if it was a relay. I wasn't sure which of the pins on the 4-pin fuel pump connector were power, so I tried a few different combinations and didn't seem to get any voltage.

Any thoughts? FWIW bike was running just fine when put away.

Well I feel stupid now. That post was right below mine. Somehow missed it when skimming.

The advice in that thread worked great. I had power at the relay and at the connection to the pump. So I yanked the fuel pump, bench tested it, found it not working, and replaced it. Bike starts and runs great now.

DMF to the rescue, as always.

where did you get the replacement fuel pump? self install or did you have a shop do it?
