Hello, just aquired my first jbody, and a parts car for it. - 1989 sunbird GT 2.0l Turbo Convertable
The good car has no spark. - just wondering if anyone has a wiring diagram for the ignition system or knows of a common problem that i could test for on this car.

It has the old style coil with two plugs on top of it, one black and one grey. the large red wire on the grey plug has power with the key on and the plug is unplugged off the top of the coil. when i have both the black and grey plugs attached to the coil properly everything is showing power when backprobed with a test light.

any help would be awsome.

thanks
Greg
