Re: No Spark 85 Caprice

Went out this morning, when the engine was nice and cold. It wouldn't
start! Probably no spark again, but this time when it was cold ! It
used to always start when cold. Dang.

Twice now I have gotten the spark back after removing the air cleaner,
and tapping on the various electrical components and connectors (or it
could just be coincidence). I'll have the gf get in the car and turn
the key while I tap different components, and hope for the best, so I
can possibly diagnose it.

Also going to check for 12 Volts at the battery connection the the
distrib. Sould I check for 12 V during cranking or just with "key on",
or both? Don't want to destroy my voltmeter, if the volts are too high
during starting.

I know I have a loose connection at the alternator plug-in connector;
wiggling it changes the revs a little, but it's never caused this
before. Maybe it got worse. Just one more thing to check.

I'm still wondering why the car can start up sometimes, and run just
fine for through the cold, warm, and hot phases, with spark, then get
no spark only during starting.

Thanks for the replies. They help. Keep them coming, if anyone has an
idea !
