A mate had a 3.0 n/a Supra on a 1994 (mk4) and has a problem with it starting, it doesnt seem to be firing, just turning over and thats it!! Distributor and rota arm have been changed, ignition coil has been changed, all fuses etc are ok. Doesnt seem to be sparking or even attempting to spark!

Any ideas?!! He hasnt changed the leads but all 6 dont seem to be working so doubt its that!!

Cheers
Chris
