ZZR 1100 c1 starts runs stops !

[ConfusedTim]

Hello all , I'm new to this but hopefully someone out there in ZZR land can help me ?
My c1 1100 starts runs for a couple of seconds stops as if it's not getting any fuel ! I've tried gravity feed and hot wiring the pump but no difference . Has anyone got any suggestions as to what the problem might be ?
Regards Tim Cheers ☺
