Bad ignition switch maybe?

I recently turned my 91 off but forgot to put the windows up, and when I went to turn the key on I discovered I didn't have power. It's kind of weird because when I put the key in the ignition I still get the door dinger and door lights, things like that; but as soon as I turn the key all power is lost.


Does that sound consistant with a failed ignition switch or the tumbler or could it really be anything on that circuit?

Bad battery connections or cables.

I'm not so sure, because the couple times before that I turned the key and there was a 2 or 3 delay on the power, but it did come on. now it wont even come on. I'll go out and check some connections though to be sure.

EDIT: Well oddly enough it works fine now. This problem started the morning I left for vacation for a week and I didn't have time to mess with it. I just got back last night and now it works.

the thing is, if you turn the key and power comes on a little bit, the switch is working.

The clutch/starter interlock switch is worth looking at, if the battery checks out good to go.
