Hello all; It has been a frustrating day.....Power went off at 5:30 this morning and has only recently came back on, I have not eaten enough, its very hot and humid and I am not thinking clearly to get this problem sorted out.
I have here a Super Major that had injection pump issues. I was in a hurry (Never a good thing) and didn't get it set up as well as I should have to remove the pump. The pump came back from the shop set up to inject #1.
I removed the rocker cover and roll the engine over to get #4 valves rocking which should have #1 on TDC right? I then check the timing mark on the flywheel. I believe I should be looking for 23 degrees but cant seem to get the pump marks close to matching. I am certain I am on TDC Compression for #1 (#1 is at the fan end right?) I have a good flow of fuel to the pump (it has had an electric pump installed) and there is good air free fuel to the injectors.What am I doing wrong?
 
It would help to know which pump you have, Supers came with two, one a vacuum governed, one a Minimec. The pump timing marks are in two different places. The early pump mark is on the side, the later pump has a pointer and mark on the top of the pump drive.

The easy way to ensure you are on No.1 is to see if the clamp bolt on the pump drive coupling is below the drive shaft. Then set up on 23 on the flywheel. The marks on the pump should then line up and can be adjusted using the coupling bolts.

It is very easy to get the pump timing 180 degrees out when refitting the pumps.
