Mark at M.A.developments will tell you what pulley trigger to use.

Were the plug leads marked on the loom because SM4 does not fire as you would expect.

o/p Inj 1 - pin17 fires cylinder 1
o/p Inj 4 - pin16 fires cylinder 2
o/p Inj 2 - pin32 fires cylinder 3
o/p Inj 3 - pin31 fires cylinder 4

What coil set-up do you have because that also fires as above.
