1066 won't start

Injector pump gear got unmeshed with the idler when we pulled the front cover off. So I am suspecting I am out of time. However, when I put the engine at 18 on the flywheel to check the timing of the pump, the pointer and mark are almost right on. Off by less than the width of the pointer. Since the pointer on the flywheel has a slight bit of play to it, you can get the pointer and mark on the pump, to match up with the pointer and 18 on the flywheel.

How exact is the timing? Is that the culprit, or do you guys have any other ideas? Thanks.

By the way, as was pointed out earlier, I am not an IH mechanic, but would gladly take the advice of one, shade tree or otherwise.

Thanks again guys.

Try pulling the pump out and turning it a full turn and lining up the marks again. I put a pump on our 966 it did the same thing. The book said to line up the pointer and try starting if the engine will not start turn a full turn and try again and it worked. The pump gear turns the same speed as the crankshaft and it must be geared down inside the pump itself. I hope this helps.
