2013 300i fuel pump won't prime
« on: August 10, 2020, 11:46:38 AM »
Replaced the spark plug on the bike.
Now the bike won't start.
When I turn the bike on the fuel pump doesn't prime.
The bike cranks over.
I replaced the battery and the micro relay.
Still doesn't start.
At the connection to the pump I have .184v on the green wire and 12.8v on the salmon wire.
Any help is appreciated, thanks.

Pulled the fuel pump and bench tested it.
If I supply power to the green and yellow-green wire I get fuel flow.
I suspect the fuel pump is ok, and its something else...

If I power on the bike the same 2 wires have less than a volt.
