ok. Not getting fuel out of the high pressure pump.
New head gasket and the engine is back together. I have bled the fuel system to the high pressure pump and I can get it's outlet to drip a little if I loosen the outlet fitting while I'm pumping the lift pump.
Problem is that it is not pumping when I roll the engine over. I removed the shutoff solenoid an put on a spring to pull it fully open so that should not be stopping the fuel.
I'm stumped why the high pressure is not pushing fuel.
thx, john

The handle on the lift pump doesn't work well enough to bleed the system. The engine must be cranked with the starter in order to bleed the system. Not sure if that is what you meant when you said " roll the engine over" I usually tie down the decompression lever so when the starter cranks it won't start and it cranks faster (no compression)... be sure when you do this to have the throttle on full "WOT"... this opens the rack fully on the injection pump so the air bleeds out much faster.
