Up for sale is a good working, used Saab 900 / 9000 6 cylinder ignition coil pack assembly. This will work on 96 97 98 V6 Saab 900 - kind of a rare car!  These generally last around 150,000 before a failure, but when it does fail it can prevent the car from starting. If you have no spark this is often times your problem.  Some external corrosion is normal, but if there is a significant amount, this can cause this unit to NOT WORK!   Generally if there is a problem with the ignition system on older Saab's it's either this unit or the wiring to the crank / cam sensor that goes bad. These are fairly easy to replace, and they are over $387 from Saab for an OEM Bosch unit.
