Some of you will recall my
vapor lock thread from about 3 weeks ago. Car died while warm and then restarted a few hours later after cool down.
At the time, I checked out the ignition system and did not find any obvious culprits. On Saturday night, I was planning on hitting a local cruise spot and experienced the same condition while in my garage with a cold motor......was getting fuel and engine turned but no spark what-so-ever. I rechecked all the connections and after about 3-4 more tries it finally fired. I suspected a faulty tach lead (short) and replaced the terminal. She fired up again, so I buckled in and proceeded to go for a drive.
I was at the bottom of my driveway and she died, again. Just lost all spark! I quickly summoned my neighbors (this is around 8:30pm) and together (with my oldest son steering) we pushed her up the driveway and back into the garage.
I followed the MSD ignition tests to the letter, but the results were inconclusive (I'll be the first to admit that electrical stuff is my weakness). I suspect the coil now, but just to be safe I'm sending the MDS 6AL to the factory repair facility today for a diagnostic check. Worse case is I pay a max. of $55 (plus postage both ways) for this service, which to me is cheap insurance for peace of mind. Getting this car flat bed towed is no fun. I also ordered a new coil, cap and rotor from Jeg's this morning to round out the repair.
Yeah, I might be "throwing parts" at the problem, but I feel pretty confident that it's going to go away after this. I also ran a resistance check on the magnetic pickup at the distributor and was showing over 600 ohms, which is within tolerance.
