So I got my camaro running. It needed a new ecm, got it one. Started it up, ran fine, let it warm up for a min and then turned it off. Came back an hour or two later, and plugged in my Innovate A/F meter. The sensor was already in the exhaust so all I did was plug the power into the ligter socket. Turned the key to on, lights came on and everything, turned it to start and everything dies. Now there is no power anywhere, no lights, no guages, nothing.
Measured the battery, it's got 12+V. Checked all the fuses under drivers dash and the fusible link near the batt. They are all fine.

Where else are there fuses, or fusible links? Could using the lighter socket have shorted something out? What fuse would that be? Any ideas are welcome, thx.

Check the large terminal on the starter selonoid. That's where all the power comes from. Those wires have fusable links on them.

I figured it out. It was the screw terminal near the battery. The one with 2 or 3 fusible links between it and the starter. Just wiggled it and everything came back on. Thx though.
