Sorry I missed your previous page. your right its starving for fuel due to an air bleed. when it dies take a fuel filter off. if it is empty then air is getting in. or you have pluged your filters. have you changed the primary on the engine? this is a common spot for an air bleed as people lose the copper washer or pinch the oring on the cup.
if you find it is air you can cheat the problem to find it by over presurising the fuel low press side and where the leak shows up is your probem. or you can put a piece of clear line on the fuel return and watch for bubles. it will stop when you find the problem.
and to help the priming I use a simple vacume pump for bleading brakes. I often end up doing this on many boats so It pays to be portable. using the simple cone on the end of the vacume line you suck the fuel up to the primary through the bleed port and then again on the HP feed to the injection pump. This will also allow you to see the bubles in the suction line if you have a bleed further up the line and saves the time on the starter. This vacume pump is cheeper than any electric lift pump.
then do the fuel flow test.
