I have switched relays and no change, I guess it is down to temp sensor . . .

I tested the pump,the connectors both before the tank and at the tank, all had continuity. By some magic the pump ran and continued to run.

Typical tank connector problem. 

I went start last night (bike has sat for three weeks or so) same thing, no pump, this time wiggle the wires at the disconnect and pump runs. 

Typical tank connector problem.  Again.

Try again today nothing will make it run. I tear into it, cut out the connector, put 12 volts to the green /white wire pump runs.

Pump is good, tank connector is whack.

Ok check continuity for that wire to the temp relay, all good.

Continuity to red/green wire on fuel injection/pump relay???  That's where the power for the pump comes from.

Clean the connectors on the black fuel pump relay , no change, I hooked a 12 volt light on the pump wire(green white) so I will know if I get juice when I hit starter button.

Sounds good. 

Questions. If the starter button will connect to spin the starter does that mean it is sending juice to pump relay, or is there something to check at that end?

The pump relay gets energized by the ECU.  The pump relay coil gets power from fuse#1 through a green/yellow wire and is grounded through the yellow/brown wire at pin #7 on the ECU.  The green/yellow wire on the pump relay should have 12V when the ignition is turned on.  The red wire on the pump relay should have 12V all the time.  The start button has nothing to do with the pump relay.  If the starter runs, the button is working.

 I have switched relays and no change,

What relays did you swap?  Put them back where they came from.  You could be introducing new problems.

I guess it is down to temp sensor, I have a extra temp sensor I could switch with, can I just hook up the spare sensor off the motor and ground it to the block?

It's NOT the temperature switch.  Ignore it.

I installed one in a K75 and if running low the fuel pump would get starved and kill the bike on right hand turns and then take several minutes sitting on the side of the road until the pump would reprime itself.
