On the passenger side unibody section in front of the strut are a few mission critical harness connectors. They are somewhat hidden by the airflow meter and other stuff, so they're hard to see.
Circled in red, the rectangular connector is the power distribution connector for the car.
Circled in yellow, the triangular connector is the connection down to the starter solenoid.
If they are both plugged in, and the car won't crank, (as in rotate when you have the key in the start position) unplug the starter harness and check for power at the car side of the harness while the key is in the start postion. (you're checking the black with yellow stripe wire)
If there's nobody home on the car side of the starter solenoid harness, unplug the clutch down switch and try again. The switches go bad, and the little yellow plastic button that depresses it also gets broken. This will prevent the starter from operating. Unplugging the switch opens the interlock circuit, and will allow the starter to operate any time the key is in the start position.

If you want a quick go/no go test, jumping
positive battery voltage onto the
mate of this ^^^connector^^^ is the easiest way to "jump" the system. Note it's position in the connector, and jump the
mate to this connector using an alligator clip on the end of a wire. **I would be leary of doing this, as the current required to pull the starter solenoid in to actuate the starter motor is pretty large, and you may damage the pin in the connector. (once would probably be okay, but I wouldn't make a habit of it)
The hard way to "jump" things is to unplug that wire at the starter, then plug another wire onto the small connector, and then touch that to the
positive terminal on the battery.
If you're feeling froggy, you can also just short accross from the positive starter feed wire from the battery to the small terminal with a small screwdriver, but there's gonna be sparks! /ubbthreads/images/graemlins/ooo.gif
Make absolutely sure the car is in neutral before doing this!!!
Here's a pic of the whole starter sub-harness to give you an idea of what you're working with.
Good luck!
