IP swap done. 300D won't start.

Spent most of the weekend pulling the (known working) IP out of the parts car and into the daily driver. Took a while - but there were no surprises and everything went well - so I think anyway.

Pulled the fan, the vac pump, the intake manifold and then the IP itself. Engine was at 14 deg when the locked IP was placed back into the engine with a new O-ring.

Put mostly everything back together (haven't put the fan or the belt back on) - but the engine won't start.

I've cracked the hardlines and I see fuel bubbling up - not squirting like I think I should.

Any ideas? I've been careful not to burn out the starter - and only try to start 2x each min for a short duration each time.

What am I missing?

Forgot to mention - I made sure the spin-on was full of diesel before attempting to start.

Did you check if the tang was visable in the original injector pump before removing? Otherwise you may have pulled the injection pump on the wrong stroke for re installation of another one. At an indicated fourteen degrees the pump can be installed two different ways in relationship to the cam.

Put the engine at fourteen degrees again. Verify the cam lobes of the number one cylinder are pointing upward in general. Then have a look for the tangs presence. If not there rotate the engine one more time. If the tang is present and the valve lobes pointing downward.

Remove the injection pump and position it for the locking device. . Rotate the engine 360 degrees to 14 degreeas again and reinstall the locked pump. This is the most common error when dealing with the timing in of injector pumps. now if you find the cam lobes are upward in general on that first cylinder at 14 degrees and the tang is in sight.

Spray a little wd 40 into the intake for the engine to run on to help get fuel up without stressing your starter.

Shoot - I think you're right. I just checked the pulled IP and it wasn't showing the "tang".
