BJ, if you and Tanya didn't have bad luck, you wouldn't have any luck at all!
Golly, what a mess. Cooler heads must prevail. Go slow, be patient, and figure it out. We know it's not a major mechanical problem, so this should be easy. REMEMBER! It's best to disconnect the glow plugs until your sure you have fuel at the injectors. Many folks unwittingly burn them out during troubleshooting!
Things to check:
Fuel to IP (test by removing the return line from the pump. With the cold idle disconnected, it should *** all over itself.)
Fuel to Injectors (listen for click of FSV solenoid - if good, grab a spare injector and if possible and injector line, and connect to one of the top fittings on the rotary head. Ideally, the line should point streight up. keep the injector off until you have fuel there, then put an injector on the line and crank. - stand clear of the spray pattern. You can take the glow plugs out to save the starter and battery)
If you can't get fuel to the injectors, take the fuel turn-up screw access cover off, and visually verify that their are parts rotating inside when you crank. If you snapped a pump shaft, that can be a ****** to overlook.
My vote is to not mess with replacing the mechanical lift pump. Do a Holley RED right now!
