Help out an Aussie..NO SPARK!!!

Ok getting very frustrated and about to burn my car....

FC
Bosch Coils
MTX8

(+) on coils wired to 12V ignition
(-) on coils wired as per diagram for the mtx8

The coils see 12V at ignition and see about 10V while cranking...When i hold the lead a cm or so away form coil there is no spark arcing in between them.

Brand new coils, leads are not new, plugs are not new YET.

Any way to check if the ignitors in the ECU have pood themselves, because i cant think of anything else atm

I've no clue........but the ignitors themselves, are in the lead and trail coil assys themselves and the ignitors circuitry is grounded thru the base of the coil assy's.

This bothers me. I'm sure that's not supposed to happen.

Go check yours mate....all my previous cars have seen this sort of voltage while cranking, the amount of voltage drawn from the starter is ridiculous.
