Hi everyone! I just replaced the battery cables, serpentine belt and all 3 mounts on my '01 ZX3. It took me a week to put the battery and alternator back in while I worked on the other stuff but I'm finally finished. When I turned the key the dash lit up and radio came on but didn't start. No click, nothing. When I turned the key, it felt like when there's air in the brake lines, spongy, but in my hand. Also noticed the odometer changed to all dashes each time I turned the key then back to numbers when I stopped which I've never seen it do. Tried a jumpstart but still got nothing. Could it be the battery? The dash, lights and everything turns on, even charged my phone. What did I miss? What did I do wrong?
