Jasonj, You might still benifit if you try to visulise two top dead centres because that is what you have. One top dead centre with the valve lobes more or less upward. This is the power stroke where the injection pump should inject fuel on your number one cylinder. The valves are closed.
The other crank stroke is also a top dead centre but the cylinder has just finishing letting the exhast gasses out and is getting ready to let air in. The lobes will be in a more downward or active state.
As a poster mentioned to verify the cam timing the chain cannot be relaxed or sloppy on the distance between the cam gear and the crank gear. Any present looseness on the other or injection pump to crankshaft side is okay. I also liked the suggestion of one posters method to use the welling up or point of drip test to put the pump approxamatly where it should be before you pull it again and reinstall it after correction of the other problem.
Try to relax as your wife will help give you guidance. I know mine would under the circumstances as you describe them. There is nothing really broken here only not assembled properly. It will work out.
An easier description is You are trying to inject your fuel on the correct top dead centre with no slop in one side of the chain when setting the cam to crank marks initially. Ask for any additional clarifications as you have a couple of members posting that have been where you are. Sometimes I do not explain or project my thoughts very well.
