Having an intermittent problem with my 1985 Fleetwood (FWD). She only turns over about 50% of the time. I’ve tried the classic 3 issues (fuel, air, and spark) and have found no issues. Have been asking around and think it could be my BCM (body control module) but have absolutely no idea where to find that. Any help with the location or what else could be the issue with the car would be greatly appreciated!!
