If the nozzles are fitted as per the guide, any blockage of any given nozzle would only affect that nozzle, moving the injector would prove only that the injector is not the problem 
5 o o 6
3 o o 4
1 o o 2
With the above being the numbers of the actual cylinders on the engine, the corresponding LPG injector circuits (on the LPG loom) were originally configured as follows, in relation to the above:
5 o o 4
3 o o 2
1 o o 6
(remember it doesn't matter which goes where, as long as the vapour hoses correspond with the same cylinder that the wiring is set up for)
So looking at the above picture, the circuit for number 4, top right, was erroring.
In order to eliminate the injector from the equation, I swapped the wiring, and vapour hoses, between (LPG) injectors number 4 and 6, so it is now configured as follows
5 o o 6
3 o o 2
1 o o 4
So as you can see, the number 4 circuit now controls the front nearside injector, which due to the swap is now a different injector, different vapour pipe, different nozzle, and different physical cylinder altogether.
This is how a fault with the injector, any specific cylinder on the engine, valves, blockage etc, can be ruled out.
Get where I'm coming from?
