WB,
I'm assuming fuel will run out the supply line that attaches to your injection pump. I'm assuming to that the fuel inlet strainer assembly came with the new pump you have. The inlet fitting screws into it.
If you have the 'dots' lined up, then your pump timing will be close, but as you know the pump body mounting holes are slotted. Using the timing window on the pump, and aligning the marks inside, with the flywheel timing marks in the correct position, at #1 TDC, assures it's set to factory specs.
There is a bleed screw just underneath the throttle control on the pump, I believe. Make sure you have fuel coming out there. Try cranking the engine if not. You can also remove the special return fitting at the top of the pump and check for fuel there. The pump must be full of fuel.
To get fuel coming out the lines at the injectors it will take about 12 seconds of cranking. I sometimes take an injector line off, right at the pump and check for fuel coming out there. Use safety glasses. Make sure the bolts holding these lines on, have 2 sealing washers on them, one on each side.
Turning the engine over by starter, with the timing gear/shaft unsupported, is a little iffy. There is a key or roll pin to align the shaft with the gear, so although I've never heard of these shearing, it would be wise to check that the pump is turning, possibly through the timing window. When these pumps build pressure to inject fuel, a lot of force is required. Got to go. Phil
