crank no start

[90SK]

I had this running fine a few weeks ago, started right up, then let it sit for a few weeks and just cranks. Used starter fluid it will run as long as you spray. So I pulled off the fuel lines and I'm not getting fuel to the TB when cranking. I've had this happen before and I managed to get it to work (not sure what I had done) it seems to be an intermittent issue.
I've not checked the ground behind the light will do that next, but other than that I'm stuck and looking for advice.

Cheers,
Keith
