Turns over but won't start???

It was running fine. I had rode it for about 10 minutes and pulled back into garage. Cut it off and it sat there for like 10 minutes. I tried to restart it and it won't. It will turn over but not start. At first it would start and then die when I gave it throttle. Then it would start and die, start and die. Now it just turns over but won't start at all. I checked spark and its working but when I took fuel line off tank and checked it during cranking there is NO fuel coming from the tank.

Traced down the error codes. Looks like the crankshaft position sensor may be faulty.

Crankshaft position sensor checks good.
Pulled the connector off the top of the fuel tank and it has voltage going to the pump, but the pump will not come on.
Is there any other way to check the pump? Like wiring it direct. Which seems sorta strange seeing that the connector has voltage coming to it, you would think the pump would work if it was going to.
Any ideas?
