I drove my '96 out for errands today, and went to start it up to come back home, but it started doing something really weird. The RPM started bouncing up and down, and the AC wasnt working at all (it usually works great). So, being a hot Florida day, I decided to try to restart it to get the AC working. The car never responded. No clicking, no slow turns, nothing. We tried jumping it, but the battery isnt the problem. Absolutely nothing happens when you turn the key all the way. Any idea what this could be?? We ended up roll-starting it, and that worked, but if I let it idle too long at a stoplight, it would drop the RPMs down to almost a stall. It also changed the idle to 2k?

What condition are the contacts on the battery terminals?

I checked, they're all fine. I suspect its either the starter or the keyswitch..

Run a straight 12V wire to the starter to win the switch/starter battle.

Update: Switched starter, still no good. Ran a meter on the starter, and its getting 11.6, which is pretty much what it should get. I don't know what it could be, at this point.

I know that I have at least one bad fuel injector, but I cant imagine that's preventing the engine from turning over....

SOLVED:

Turns out, it was the little button that tells the computer that the clutch is depressed....

I bypased ( or deleted ) that thing so long ago I'd forgotten all about it. Ditto for the neutral " safety " switch.
