2000-2005 cad hearse igntion problem
I am trying to help a customer locate ignition coil (on plug singles). not having any luck. All stock 4.6 from GM have 2 rail system coil packs. These particular vehicles are equipped with the standard rail system on the back of the engine but individual coils on the front. Can't find anything like it. The same motor setup in 3 different Hearses. I need the front coils - the part numbers dont cross on the originals and GM dealer said they don't exist. They think I am crazy. I wouldn't have believed the customer if I hadn't seen it myself.
