help ea starting probs

[89 S-PACK]

ive got a 89 ea spack manual thats giving me probs. it wont start.

ive put in new leads\ plugs, coil, dizzy. and ive still got no ideas why it wont start. ive got power everywhere... but im getting no high tension spark.
its getting petrol and the comp works cos i put it in another mpoint ea and it started and drove with no probs. i even have had a spare dizzy hooked up and spun it by hand with a plug in the end of the king lead with the ignition on and still nothing. all what happens is the petrol pump primes ans u can hear the injectors firing and u can smell the petrol.
