The Z would start with a jump then die but the Odyssey wouldn't start even with a jump; the starter clicked on both, both times.

I worked in auto parts for 8+ years, and it was common that people would discount the battery because the lights would turn on or you would get some indication that there was some power to the car. Bad batteries can cause some funky things to happen. I always, always, always suggest starting there before you start looking for electrical issues.

Also sometimes a car with a bad battery wont even take a jump. So that's always something to consider too.

My dad (who taught me almost everything I know about cars) was the same way. He had a Caddy that wouldn't start without being jumped. He had called me up and said the Caddy was dead, so I brought a battery charger. We charged the battery for about 40 minutes, then switched to engine start and it fired up. I told him the car needed a new battery, he said exactly what you posted "it can't be bad, I have lights and the horn works". I told him "humor me & replace the battery". He did and Voila!!!! no more problems.

I'm pretty sure JAR has replaced the battery already...

Cars with ECU's need between 10 to 10.5 volts to operate. Anything less, they won't operate to save themselves. And they don't like voltage spikes either.

A battery can show 12 volts and still be bad.

You if you can't get a car to start by jumping. Remove one cable from the battery and jump the car with the battery out of the circuit.
