There is a valve just above the fuel input on the pump, undo this and pump the hand pump to bleed any air out of it. Much like bleeding a radiator.
Once you're sure all the air is out prime it some more using the hand pump and crank it will you pump the hand granande.
If it still fails to start undo one of the injector pipes and see if theres any fuel comming out while it cranks.
If theres no fuel comming out you need to check theres a live at the stop solinoid. I'm not sure 100% if theres a security plate on this pump to stop you getting at the stop solidnoid. If there is then the pump will have to be removed and the plalte ground off.
Is there light under the clock flashing or is it going off when you turn on the ignition?
