my question is when you have a FIP pumpfrom another car how can you tell which cylinder it is firing on as the engine turns over twice to the pump once so if you set it at the timing marks and cannot see the chain to get the links lined up how can you tell which cycle its on because you can set the engine to no 1 TDC firing but if the pump is firing on no 6 it will never.
Thank you for any replies

When the engine is locked at TDC number one firing, the number one cylinder valves will be flat across the top and the Woodruff key slot on the pump sprocket will be upper most. Turn the injection pump clockwise until the Woodruff key on the pump matches the sprocket key position.

\\but the matching up of the woodruf key the pump could either injecting to No1 or \no6
as the engine turn twice the speed of the pump The pump does 3 injections to 1 revolution somhow do you tell which cycle its on? when the front cover is off you can tell by matching up the bright links with the marks as they do not line up on the next turn of the engine

If the engine is locked at TDC number one firing and the number one cylinder valves are flat across the top, the key way should be uppermost on the pump sprocket. Match the pump key way to the position of the sprocket key way. It's not rocket science. If it was 180 degrees out the number six valves would be flat across the top and the sprocket key way would be at the bottom.

If the pump is set a t no 1 the key way is upright if the pump is firing on number 6 the key is upright it was the same in the old day with distributors you could easily get the the timing 180 degrees out the pump is driven at camshaft speed same as a distributor was so how do you tell which cycle the PUMP is on not the engine
If you had a pump sent to you that was taken out of second hand engine that was not set at tdc number 1 how do you tell which is number 1 Firing position? or dont you get what im saying

As the FIP turns at half engine speed, If the engine is locked at TDC #1 firing, with the FIP woodruff key at the top it will be in the correct part of the cycle, it cannot be 180 degrees out..

Turn the pump clockwise until the key way is upright and matches the position of the sprocket key way with engine locked at number one firing. That is the start point. The firing order is 1 5 3 6 2 4 . So number 6 CANNOT be firing with the key way upright. The key way is at the lowest point when number 6 is firing.
