injector pump problems, advice appreciated

Hi, my disco cut out on me at weekend, was running fine, ,cut out and hasn't started since.

Turns over fine, cambelt in one piece, fuel getting to filter to injector pump then doesn't come out!

I know nothing about diesels to be honest, is there any parts within the pump I could change that would help?

Any suggestions welcome. Richard.

is the solenoid working?try a live feed to it and try again

Thanks will try that tonight
