2002 Chevy Camaro Z28 will not start.

I would check for continuity on your battery cables particuarly the positive.
if I remember correctly there are two wires on that terminal. One for the starter and another for the rest of the car.

I saw a lot of new cars come in where the battery terminals were overtightened from the factory and the terminals eventually came out. often times they leak before they come all the way out and it dumps acid down into the cable. When this happens the cable erodes from the inside over time eventually leading to failure. I've also seen cars that come in after the warranty period where the original battery had failed and the cable had not been replaced. the acid sits in the cable and over time the acid inside the cable eats the wire in two. We replaced the cables but I do not think this was a service bulletin or recall.



So what happens here is a car that "turns on" but doesn't start because it doesn't get any juice to the starter. When you unhooked the battery you might have broken the last of the few strands left that were still on one piece.

Agree with Z65--i saw enormous corrosion on my 1998 down into the cables and had to cut them back about an inch each and re-crimp a new eyelet.

Just an inch? I've seen corrosion in the cable as far in as a foot from the eyelet.
The gauges, stereo and accesories turning off or acting strange may be normal. Some cars only supply power to what is absolutely necessary to start the engine when the switch is in the start position. Which in this case may only be the ECM, starter fuel pump and ignition.
