( Middle coil Pack ) #2 not firing.. hear clickity click. ( top coil pack ) #3 also has orange spark (low/bad voltage), and #6 seems to be on its way out blue with a mild orange spark . What could cause this?? What controls the Coil pack?
The coils are powered by battery voltage. They are controlled via the ignition control module (under coil packs) which allow the field to build in the primary coils at such a time that the spark is required it will collapse the field into the secondary coil inducing the high voltage required to jump the spark gap. You will need to measure the resistance in the coils (primary and secondary sides). This will tell you the condition of the coil pack as well as the condition of the ground. Take off the control module and check it for corrosion (bad ground) as well.
Is the car alright after fixing the battery lug and boosting?
