92 Ford Explorer won't start

[abberdabber]

I have a 92 Ford Explorer that won't start. I have had the crank sensor and the computer replaced but it still is not getting fire. At first it would just crank but wouldn't start. Now nothing even comes on when I turn the key. Please Help!!

Either the battery is completely dead, the switch is bad, or the pcm is shot. The switch is easy to replace if you want to try that first. I think they are only 20 bucks or so at the auto parts store, you'll just have a new key for the ignition and your existing key for the doors and hatch.
