get a battery jumper box. they are only around 30 bucks on sale. well, well worth it.

look up starter in tutorial link in my signature.

if car isn't trying it's not likely the bat, could get it amp tested.

spark/fuel/air

fuel - turn key just shy of trying to start, should be able to hear pump (may not be used to trying to listen for it though; pumps in trunk, behind back seat in hatch), prime it this way 1-2 times then try to start see if that makes a difference. Can also check by pulling plugs, wouldn't start with that.

spark - pull plugs, check gap; try to turn over with plug pulled (being held or safely isolated electrically, bring a friend). If you haven't replaced the distrib cap n' internals they are cheap, and prob not a bad idea.

air - if the car's not knocking when it is running, not firing rich or lean and you don't hear a vacuum leak on turn off your probably all right here. Probably. You can pull the air box (bypassing the filter) temporarily in the garage or drive way and see if it makes any difference.

if any of the common consumables are getting on the old side or worn it wouldn't hurt to replace them (pcv/air filter/vacuum lines/distrib cap/distrib cap n' rotor/plugs/wires/fuel filter)

he said starter is clicking with no turn over. means power is getting to starter.

How could it be the ignition switch if your starter is clicking? when you turn the key to start momentarily, you are sending power to the starter momentarily. there is a wring diagram in the starter trouble shooting tutorial.

the last wire sends power to starter. second to last sends power to computer to assist in start. if it is the switch, it would take someone awfully experienced to figure it out. if the computer doesnt get the start signal it is harder to start but it much more common for something else to be the problem.
