Super Major Injection Pump

I have a Super Major with a Simms vacuum advance injection pump. The engine will not start, the fuel system is bled to the injectors. No smoke when the engine is cranking, the injectors have tested ok, the rack is not stuck, the plungers are not stuck. If this style pump is 180 out would that affect the operation?
 
You might also like to check which pump you have actually got so that you can time it perfectly. Off the top of my head I think there are 4 different sims vacuum pumps that will fit the major series. I will dig out all the details if you wish. Mike
 
Hi. Ifthis comes out OK it should give you all the required detail to time it correctly.

The picture in Mike's post showing the pump coupling is incorrect.

All Majors from 1952 to 1964 are on Number 1 cylinder when the coupling clamp bolt is below the drive shaft. If your timing marks line up with the coupling clamp bolt in that position you are 180 degrees out.

This picture is taken from the Fordson Tractor Workshop Manual. A rule of thumb we used when removing pumps:

Before removing the pump always check the position of this clamp bolt. If you do this and then put the pump back on with the marks lined up you will always be right.
