Im getting no spark from the coil so I replaced the pickup module my 88 GTA started and ran for 2 min then shut off. The - battery terminal was loose but after i reattched it I again had no spark could that have shorted the relay? The was also a fan wire spliced into the coil wire could it have been that? If not either of those what else could it have been im at a loss so any help would be much appreciated.
