well that was depressing! swoped the wiring over to coil order i.e coil1 -cyl 1 and it now doesnt try to fire any cylinders?
back to the drawing board!

Try doing as previously suggested by actually finding the firing order by testing?

Take a step back.

First, do a crank scope. Check the cam sensor is still working.
Second, crank it over, and check it's still synchronising:

If it is, it can only be incorrect timing, or not enough/too much fuel.
Take all the plugs out except cylinder 1, then take a crank scope and send it to me so I can check the crank and cam sensor angles.

i will do a check later 1) i have re done the scope and it is still the same 2) will pop the plugs out and stick a pressure gauge on see the order the cylinders make compression 3) could it be the cylinder phasing in a strange place ? i.e the sensor picks up a pre determined point that is stored it knows then in so many crank pulses it is cylinder ??? as that reference could be anywhere ?

If you know the proper firing order it doesn't matter where the actual cylinders are positioned so if you put

F/O 123456 ( as you say)
O/P 123456

Put ecu pins in the holes that relate to these cylinders.

So 1 in pin 10
2 in pin 18
3 in pin 1
4 in pin 26
5 in pin 11
6 in pin 27

checked this today
it is how it is wired from what i see
i will put a spark plug lead from the coil to plug and try a timing light and check firing position
it could be the phasing if the cam sensor? may not actually be on cylinder 1?

check

Stop guessing and do as Alex said and make a scope trace with plug 1 in.
