Then be sure to park on a hill! ;)

Over on another thread about not starting, someone referenced the WOSP hi-torque and lightweight starter sold at Pelican. It's only $209, and built on the Nippondenso starter core. Consider it as good and inexpensive insurance.

Check the tranny strap grounds first.

Put your bro's lift to good use if you don't want to jack it up yourself.

My problem was similar, but maybe not exactly the same. Definitely check your ground strap, but if it appears to be ok (mine was) then as has been mentioned it is either the start switch (964-613-012-00) or the starter. For me, it was the start switch. It would fail occasionally and then one day just said "nope, not gonna do it anymore". I did also end up replacing my start motor, but that's because it too decided to stop working a few months later. I decided to go with the lightweight High Torque starter.

Replacing the transmission strap on my '88 cured it for me a few years ago...

I have the same problem with My ‘83 and just minutes from DE. I’m thinking my issue is in the ignition switch. PM if you can figure it out or get into the ignition. I have a lift in my garage too. Bill

Will do! You're a stone's throw from my home. Do you ever head up to Northbrook Marketplace for cars and coffee?

Yes I do head up to Northbrook. Red ‘83 Targa. Look for me.
