A dead short to the ref voltage circuit would kill the ECU.
Ref voltage being the brown/white wires you find on the boost sensor, afm etc. No approx 5volt ref voltage.....no sparky. The source of that 5volts also controls the ability of the ECU to trigger the coil/ignitors.
On grounds: a lead or trail coil that is not bolted down to the chassis will not fire. The ground for the ignitor is thru the coil/ignitor assy's body. Chances are slim that his coil assys are not attached to the chassis.

Ok, I just got back from the shop. and I do know how to use a volt meter. The ground wire is connected to the rear rotor housing, but the ground on the Tailpipe, and on the transmission housing are gone. I tried bolting the Leading and Trailing coiles, to the body, ad it still didn't fix the problem. There is no spark at the coils, down by the headlight, there is another plug. and it sparks there just fine. I will check out the ref voltage.
