I found this thread in a search because I am suspecting my ign switch for a different problem. My car is just all of a sudden shutting off while driving and both times was moving very slowly and both times the car was running perfect up until it just shut off. The first time 2 weeks ago it did it pulling into a cruise night. We were testing for spark and there was none while cranking. A friend had a new coil and that worked. So we actually hooked my orig coil back up to replicate the problem and the car started. I figured it was the coil reaching the end of its life. We re-hooked up the new coil and I made it all the way home (about 15 minutes). I bought the new coil from him and figured problem solved. The next week the car did it again in another friends driveway. Tried 3 different coils and no spark from any of them. Ended up having to flatbed it home. Now I am thinking MSD box but according to MSD tech dept, the box is not suppose to quit like that, when it is done, that's it, no gradual death. They were thinking coil also until the second time.
I did check all the wiring from the box and it is all good. now i am suspecting the ign switch.
The car has been sitting for almost 2 years due to back surgery and then a year later knee replacement surgery. drove it a few time last fall with no issues. Recently I drove it 3 different times with no issues before having this problem.
Any thoughts?
Lesson learned here is have much more spare parts on hand in the trunk and have a much better selection of tools to work on the car when stranded with a problem.
My spares parts kit will now contain new, ignition switch, fan belt, cap, rotor, coil, voltage regulator, new MSD box, MSD distributor magnetic pick up.
Thanks...Dave
