Sounds like a basic electrical problem. Check your battery terminal connections, and the voltage of the battery. Should be about 13+ volts, like 13.5-14.0 volts. If you don't have the correct voltage, then have an autoparts chain run a load test on your battery and alternato (usually a free test), to check that the alternator is putting out the current and voltaget needed to charge the battery, and the battery is holding the charge.
 
If both of those are okay, then other end of the ground cable(non-battery end), to make sure there isn't any corrosion there. You can also check the resistance of that cable to make sure you aren't dropping any voltage.
 
Then check the positive cable connection at the starter, to make sure there isn't any corrosion there either and it is a good tight connection. Caution to disconnect the battery while you are doing that, so that you (or your wrench) don't become the short to frame ground.
 
Repetitive clicking can be a relay, which doesn't have enough voltage to stay latched.

So it turns out my third-party security system had an starter lockout relay. When I pulled the battery, it reset and armed the security system, which then kept my car from starting. I pulled the manual and set it to Valet mode, was able to start the car again.
 
But, after idle operation for 5-10 minutes, my engine dies. No engine codes, no check engine light, it just stops firing. I connected the jumpers to test for the fuel pump being non-operational, but I was able to turn the fuel pump on. I also decided to try leaving the ignition on to see if I could heat up the Ignitor module. When I did this, 4 out of 5 times the car would not start at all. So for right now, I am guessing that it might be a bad Ignitor.

does the security system turn the ignition off?

It has a starter disable relay for when it is armed.
 
Actually, I forgot to check the internal resistance of the pickup coil as well. Turns out that the pickup coil is off its mark as well. Maximum internal resistance from G+ to G- terminals should be 275ohms, but mine is around 305ohms, so it looks like I may need a new distributor instead.

I'm confused over your description of 'not starting'.
 
Are you saying that the starter does not spin up and crank over the engine? or, are you saying that the starter spins, engages the engine, turns the engine, but the engine doesn't fire up and run?
 
If your security system has a relay which stops the starter from getting it's power, then it won't spin and the engine won't crank.
 
Which no-start symptom do you have?

The starter would not spin. That problem is gone because I just disarmed the security system and everything was cool.
 
Having determined that the pickup coil was out of spec, I replaced the distributor, re-timed the engine, and drove the car yesterday for about 120 miles. Everything was great, except I noticed that it seems to lack power. Could that be an issue with the timing? Maybe I timed it incorrectly, not sure.
 
I was driving it this morning down the Interstate, and the Check Engine light came on. The car did not stop driving, but something is definitely amiss, so I need to find a table of engine codes and which OBD pins I need to connect to be able to read them.

Yes, I would suspect the timing is off. That could account for both the loss of power, and the check engine light on (due to fuel not being completely burned).
 
You are probably also getting poor gas mileage.

I have a code manual, and if the timing is off, I would move the distributor slightly in the opposite direction of rotation( advancing timing).
 
If you do this while running, you can hear the engine rev up and down. Always mark the distributor at the pad where it mounts on the engine for a good reference point. Then move off this reference in 1/16 inch increments.
 
Checking codes for the 5S- engine, the manual shows the Data Link Connector at the brake master cylinder in the engine compartment next to the left fender. Opening the cover lid, you should see terminals in groups left and right. The group on the left is the diagnostic terminals. The upper right corner terminal and the one under neath it, is the diagnostic terminals. Also the terminal to the left of the one underneath.
 
Short the terminal to the left to the terminal in the upper corner. Have the key on, but engine NOT running. Remove the jumper AFTER turning key off.
 
The codes flash in .5 second flashes. If 2 is flashed, it takes 1 second. Then you will get a pause of 1.5 seconds and if their is a second digit it will flash. If its is 5, the light will flash 5x in 2.5 seconds. 25 is lean mixture. 3 is ignition signal.
 
Codes start at 1 and go to 85 on your model. After both digits flash you get a 2.5 second pause and another code may flash if it is stored. This code retrieval repeats continuously until all codes have flashed. Then after 4.5 second pause it starts all over with the 1st code again.

02 Camry Heater Box Assembly Replacement by TLeesaM

My 02 Camry has 59,300 miles. In past 6 wks, the heat only comes out of the top (dash) vents. No Heat from the bottom, regardless of the settings on the dial. Dealer sez the heater box assembly needs to be replaced which means the dash wud have to be removed. Estimate for parts and labor $2997!!! LOL. Has anyone had a similar problem? Any suggestions (other than live with it).

For $3K, I'd be getting a 2nd or 3rd opinion, and one of them would not be a dealership. Find a reputable independent service shop that handles Toyota's.
 
I don't have my service manuals available, but I would hope that they could just fix whatever the problem part is, as opposed to replacing the whole heater box assembly. Heck, you just might have a bad selector switch.
