When you turned the key, did you hear the starter solenoid click, or was there just nothing whatsoever? Were there ANY lights on the dash? Does the radio work? How did you verify that there was no juice going to the ignition fuse?
With the information given, I would assume a dead battery. This can be tested with a voltmeter, or by having it tested at a shop (eg, Autozone can test it for you).
If this is the case, the question is what caused the battery to drain? -Just an old, bad battery that won't hold a charge. -Excessive amperage draw on the system when the car is off. (Again, can be tested with a voltmeter). -Bad alternator/generator.

Well, you didn't answer all my questions. How did you verify that there is no power at the ignition fuse, or at the starter? The more information you can give us, the more we can help. If you're vague, then all we can offer is vague advice. First off, the ignition fuse has nothing to do with the starter. How did you test this for power? Did you have the key in the 'on' position, and test both terminals that the fuse plugs into -- using a voltmeter set to DC volts? If you aren't reading power there (on either side of the fuse terminal), then that would mean you've got a faulty feed from the battery, which would render ALL of those fuses dead. The same wire powers a 'plate', which feeds the fuses on that side of the fuse box. This is assuming you meant the ignition fuse in the underhood fuse box, and not the PCM IGN fuse in the driver's door jamb. What do you mean there's no power going to the starter? Are you deducing that from the fact it doesn't run, or did you actually test for power? There are two wires connecting to the starter, one of which is a cable connecting DIRECTLY to the battery's positive terminal. You MUST have power on that line, when a circuit is completed. The smaller purple wire on the starter is the solenoid control wire, which connects to the theft deterrent relay, which connects to the ignition switch via a yellow wire. If VATS is not activated, and you don't have a 'security' light on the dash, then that would leave you with a few possible problems: 1) Faulty ignition switch 2) Faulty yellow wire going to the Theft Deterrant Relay under the dash. 3) Faulty yellow wire going to the Clutch start switch / Neutral start switch. 4) Faulty Theft Deterrant Relay, neutral start, or clutch start switch. 5) Faulty purple wire going to the starter solenoid. 6) Faulty starter solenoid (need new starter motor). I'm sure that narrows things down for you. But, it's easy enough to 'rule-out' the bulk of that list. I would use a voltmeter and test the purple wire at the starter solenoid, and see if it is getting any voltage as someone else turns the key to 'start'. If you get voltage, then that narrows out #1-5 above. In which case, you probably have a bad starter motor, which can be tested if you bring it in to Autozone or the like. Or, visa-versa, you can take the starter in for testing first, then procede to check wiring if the starter is ok.

Maybe its in your shifter if you have an auto ride. A faulty switch from the shifter will keep starter from working because it acts like its not in park, but everything else will work.

Isn't there a switch on the clutch that must me activated before the started will engage? I would check that before you starting tearing into your steering column checking to see if it is indeed your ignition switch.
