Question about 2003 Pontiac Vibe
I have replaced the battery about 4 months ago. Cables seem tight and clean, and headlights turn on bright. I was wondering if I should begin by looking at the starter relay (if so, it looks like there is on in the main fuse box and one behind the glove compartment), solenoid, or the starter?

Check that battery connections are clean and check engine ground. Also find what's clicking and make sure it's well connected and working (likely the relay you are looking for.)

If the car doesn't turn then the starter motor or its relay (yes, the one you found) are either not activated because the ignition key switch is defective or are defective themselves.
To find out which you must test them on stages. Activate the starter relay yourself directly: jump the command wire that comes from the switch (the thin one) directly from the battery - if the relay clicks and the engine starts turning then the switch is defective; if the relay doesn't click then the relay is defective and it will have to be replace. If it clicks but the engine doesn't turn then you will have to do one more test - power the starter motor directly from the battery (+ side) with a really thick electric cable: if the motor turns then the relay is defective; if it doesn't then the starter motor itself has failed and it will have to be replaced.
When doing the tests be careful at what you're wearing - no loose clothes that could be caught by a belt or pulley.

I have seen similar "crazyness" caused by communications problems in the computer network. If you scn your entire computer network you will most likely find several "U - codes" (U1000, U1006, etc.) which indicate that modules are losing communication with other modules within the network.
These type of problems are usually caused by a faulty charging system (sulfated, shorted battery, bad alternator diodes, Loose/corroded battery cable connections, etc.) or loose or corroded connectors at one or more of the computer modules.
Scanning your computer network would be the place to start. The modules like to tell on one-another. For example: if the communication loss is in the body computer, the engine control module and/or the instrument panel module, and/or the antilock brake module will have codes saying that the body control module was/is not communicating. In this example, I would take a hard look at the connectors at the body control module.
If several of the modules are all reporting loss of battery voltage at the module, then I would suspect a battery cable, bad ground circuit, etc. Please note that the engine control module will usually NOT report this type of code because it does not use capacitors to keep it "alive" with the battery disconnected like some of the modules such as the body control module and the passive restraint module.
