Remove the side cover on the pump and look for the timing marks. Rotate the engine over to were the degree marks begin. Slowly rotate the engine until you see the two marks line-up. I think the engine will be about 8 degress before tdc. Remove the fuel pump and turn the crankshaft one revolution, it must be back on the same timing point it was removed. This is to correct the timing that is "180 degrees out".One trun on the crankshaft should get it back in time.
Tried that and didn't work. I forgot to mention that the first rebuilt pump froze up and sheared the keyway pin off. That's why I had to replace the drive gear and the shaft. Thanks Skip
It does sound like it is out of time you tried the procedure listed above? If it is white smoking you are getting fuel. The problem is it is just not at the right time. Most likely injecting on exhaust stroke instead of compression.
Well, if you time pump to just before Top Dead Center on #1 compression stroke you should be where the gears are set, assuming that the camshaft is not out of time to the crank. Pull the #1 injector, pull the valve cover, rotate engine in natural direction, watch valves on #1. when the intake valve opens, the piston in #1 should be traveling downward, verify by putting dowel rod, or piece of bronze wire in #1 injector hole so it rests on top of piston(don't lose the wire in the bore), continue to turn the engine over, as the piston reaches the bottom of the stroke the intake valve should close. The engine is now starting the compression stroke. Watch through the window on the side of the pump, and continue to turn the engine over. The timing marks in the pump should line up shortly before piston reaches top of travel(again with the dowel or wire), This should be no more than 15degrees of CRANK rotation before the piston reaches the end of its travel. If the marks didn't line up before reaching top of piston travel stop at top of piston travel, and mark flywheel or front pulley. Then continue to rotate engine while watching the pump marks. If they line up slightly before you rotate crank 1 complete revolution(back to your mark) then the pump is 180 degrees out of time. To remedy this, turn engine until timing marks in pump line up. Mark crankshaft position, accurately as possible. Remove injection pump, taking care not to rotate pump shaft. Turn the crankshaft 360 degrees, one full revolution, back to the marks you just made. This will be the position the pump will need to be installed in. Again, DON"t rotate pump shaft while off. You will probably have to remove front cover over drive gear and reposition it so that the pump key way will line up. Once you have the pump set to where it has its timing marks lined up and the engine is slightly before top dead center on the COMPRESSION stroke, it should run.
