TOP COIL OF THREE HAS NO SPARK

1999 Pontiac Bonneville • 235,000 miles

A couple of months ago I changed the coil out and it seemed to be working for a say or so. I also changed the plugs at the same time. I tried to change the coil out today and the results were still no spark to the top coil, the bottom two do have spark. I made sure all plug wires and coil wire and connections were clean and snugly in place, still no spark to the top coil.

Module most likely has failed. Have it checked to confirm. You can remove it and have a parts store check it for you.

Are you saying the coil has failed then.

No, I said the module. That is the piece under the coil that it bolts to.
