Yesterday I went out to drive to my next appointment after lunch. I turn the key, and nada. Zilch. Zippo.

No lights on the dash, and nothing was operating, like the radio or the fan. But, I could see lights on some of the devices I have plugged into the cigarette light, so I knew the battery was still ok.

I flip the key back and forth, from the off to accessory, then back again, then from off to run to start. Once in awhile, i was able to hear the radio kick on as I switched to the ACC, but it was intermittant.

I took off the shroud around the steering column and I could see the bar move from the lock cylinder to the ignition switch. I fiddled with the wiring harness, wiggled it around to see if it was loose or something. Then I left the key in the RUN position, and tried shorting the terminals of the starter solenoid, to see if I could get it to fire. It would crank, but not catch.

After about 15 minutes of wiggling and turning the key, it finally fired up. Ran fine for the rest of the day and this morning.

When I got home, I did a search here on the board, and found the ignition switch test post and printed it out. I pulled the switch, tested the pins against the switch position, and everything matched. No signs of broken cable, worn insulation, or anything.

Today, it wouldn't start again. But when I tried to short the started solenoid terminals (with the key in RUN), all the dash lights and such came on right away, and I was able to start it up.

A friend advised me to check the physical position of the switch, as there is some adjustment room, perhaps the switch had slipped down the column far enough that when the key was in the RUN position, the switch would still be in OFF. I checked that, matching the switch position against the extremes of the lock cylinder movement.

I have a new started solenoid, but I'm not sure this will solve the problem. The schematic from my Haynes book is most unhelpful.

Anyone have any ideas?

Try holding the shift lever higher into park. IF that works, then you need to adjust your shift lever position sensor.

Oh... there should be the equivalent to a Neutral Saftey Switch on your clutch pedal to ensure that it is depressed before you start.

I'd guess it is no longer making contact.

Nomrally, even if I don't push in the clutch pedal, I'd get the dash lights. Like the check engine light, brake light, and the head lights and map lights will turn on.

Here, I get none of that. But stuff that's plugged into my cigarette lighter outlet is still on.

This morning I started my bronco up at 6:30 AM and took my son to work, later in the day I was on a mission to get an iron on canvas repair kit. Started her up, went to Kmart, started her again, went to a dollar store, started her again, went to an arts and crafts store, went to start her up... turned the key, and didn't even hear a click. Ironically I had just cleaned my terminals the day before, and last month installed a new grounding bolt for my starter relay. Called AAA. My battery tested at 10 volts! After the jump, with the engine running... 14 volts (just as it should be)

$70 later and I have a brand new 8 year warranty battery.

What is the voltage on your battery?
