Xud non-start

[n0v0s]

So it's been sitting for over a year, but starts up instantly. Runs fine but brakes were siezed. So I went to drive it forward with the intention to get the brakes to unsieze. I applied some revs, but it wouldn't budge.

Left it to idle for a few seconds, idle speed had dropped a bit. Nothibg drastic. Maybe from 1k to 6/70,0rpm. But this happens sometimes, thought nothing of it. Turned engine off. 

Went to re start about 5/10 mins later and it wouldn't fire. Not even catching. Figured one of the fuel hoses was a bit suspect, some slight perforations in it - so loading the engine may possibly have made it draw some air into fuel system.

Changed line, plumbed in priming grenade. Fuel coming to pump inlet. Still no start. Cracked fuel line unions off at pump, no fuel coming through.Checked solenoid. Has 12v. Removed solenoid - plunger was stuck. Unstuck it. Primed grenade - fuel came out of solenoid hole. So have fuel upto the vane pump. 

Replaced solenoid - still no fuel coming out of pump on cranking. 

Freezing my nuts off outside, can't even push it in the garage due to brakes. The grenade one way valve doesn't seem to work great although the pump is full of fuel so some fuel should at least come out!?

Would welcome any input

Cheers
