1 K100 Fuel Tank Connector Resistance Wed Aug 15, 2012 7:25 am

Hi,
I am looking at a friends K100 which wouldn't start. The first problem was lots of water in the tank, which clogged the fuel filter, and as a result the fuel pump was intermittently working. At one point the bike would start every time, but it eventually died while I was balancing then throttle bodies
I had the pump in and out a few times, but it decided to pack up altogether, even when trying to apply 12v and earth directly to the disconnected pump.
O.k so I got a second hand one which runs fine externally, but now won't run off the starter, or even when 12v is applied direct to fuse 6. I can see 9.6v at the tank connector, and on the pump +ve connection, but it doesn't spin up.
I measured the resistance between the (green/white) male pump input wire and the disconnected +ve from the pump and got 5.6M ohm, surely this isn't correct.
Can someone perform a similar measurement and confirm the reading. I would have thought it to be nearer to zero ohms.
At the moment the battery is on a battery tender to give it a boost, as I was wondering if the low voltage would be the culprit. I suspect a bad connection in the tank where the fuel level sensor is fitted.
