No spark wiring problem
Hello this is my first tbi conversion I got everything hooked up and functioning
but no spark. Need some expert advice please.
have 12v to coil 8v when cranking 0v key off
coil has pink/hot white/ground wires plugged in
bought a new distributer, electronic ignition module has two plugs right side ign control pigtail plugged in.
the left side has a orange/hot. Black/ground. Plugged in.. Was tracing wires last night heard a hissing noise then smoke from the coil just the key on. Went and bought another coil and I have found two different wiring schematics and now I'm confused..
One schemadic shows a plug going off the coil into the ignition control module left side and One plug from the ground/ignition to the other side of the coil..
another schemadic showed the left side of the ignition control module with ground and other hot wire coming from a relay?? If anyone can help me out here is what I have ...

The harness I bought was wired different. I. Had to order the black plug that plugs into the coil opposite the grey plug I'm guessing. it wasn't completing the circuit on the coil. I was only using the pink and grey wire thinking the tach signal wire was the ground... As the hot/ground wire was coming from elsewhere on the harness to the two pin in the electronic ignition module hope it finally works I'll,keep you posted thanks for the advise
