I have an 02 monster 900. The fuel pump will not prime when you turn the key on. The engine cranks over but will not start.

Checked fuses
Tested relays, ( put 12 volts on them and checked for continuity)
engine cranks over just fine
Put jumper wires in place of relay and pump runs continuous, but bike will start and run then.
Sounds like a bad relay. If the pump runs when you jump the relays, your pump is fine. Find the relay that runs the pump. And work your way backward to see which is bad (swapping relays).

I had to go through this whole diagnostic procedure myself on my 851. I had a bad pump.
:p

Can the relay still be bad if the coil moves when you put 12 volts on it and it closes a set of normaly open contacts?

I swapped the two small relays and still nothing.
Don't understand your question...

You've got to find the bad relay. Keep a relay in and jump the other. If the pump runs, than the removed one is bad. If it doesn't run, the one sitting pretty is bad. This is assuming your fuel pump is running, which you said it did...
