1987 Buick Skylark Custom 3.0L Misfire
Posted to GM Driveability on 2/24/2003 24 Replies

Cylinders 1 & 4 have no spark. They use the same far left coil of the 3-coil pack. Using a known good coil, there is still no spark. Do I just change the ignition module under the coil or is there something else to diagnose?

Thanks, Jess
