His comment about not enough fuel is because he only has fuel dribbling out of the injector lines not spraying out at high pressure like it should. To the OP is it straight fuel or fuel and air that is coming out? If it is straight fuel try gutting the FSS and get back to us.If you have a solid fuel supply ,that is no air in the supply lines, a solid fuel injection pump, a bit of residual air in the pump and air in the high pressure lines, you need to crank her over all lines loose. when it spits out fuel, from the high pressure lines, stop cranking. Tighten all lines. Then, start it. It will start and run a bit rough for about four seconds. Then, smooth out.
If this is not the case, you have air in the supply from the tank or a faulty fuel injection pump, faulty supply pump. Tell me again, why are you bleeding the air from the injection system.......what did you do?
The comment concerning "not enough fuel" is,irrelevant,as that is only determined on a test stand. Spiting fuel from the lines is not measurable.
