Hello

may have developedan air leak on the fuel supply pipe from the tank to the engine. The engine hasno separate lift pump and relies on the built in one in the injection pump. Ifa leak has developed on the fuel suction pipe then air entering the system willair lock the pump.
Try pumping up the fuel using the hand pump in the engine bay on the filterhousing, then crack off / loosen each injector pipe in turn while cranking theengine and getting an assistant to operate the primer. This will expel air fromthe injection side and the engine should fire up. The problem will be cured bychecking the supply pipe along its length for signs of leakage and repairingany you find.

If you daub each pipe joint with heavygrease and the issue goes away then wipethe grease away one at a time to highlight the problem joint
