Help! C5 won't start
 

I started my 2000 c5 coupe last night, but didn't take it out, and the battery was fine. The battery is only ~9 months old.

Today I go to take it out, put the key in, turn it, and nothing. No click, no lights on the dash or anything. The key fob doesn't function either. Tried jumping it and got nothing.

Could this be a fuse?

Thanks for your help!

Check for voltage at the battery and work your way from there.

Went back out several hours later and everything worked, dome light came on, dash lights came on, turned key and everything worked.

What could make it just not respond at all? Could this be an anti-theft thing? What would have triggered it, if so?

Maybe the car just hates me.

my camamro did that ounce. i fooled around with the fuses and said some choice words and it aventually started back up.

bad/loose main connection somewhere? I would check the main batt cables for tightness and good connection at battery end and other end. It seems to be something that effected everything.

werd.

loose ground. Or, doubtful but, the harness at the PCM is not making proper contact. Which, would only happen if someone recently unplugged it, and didn't re-install it properly. As long as that didn't happen, then chances are you have a loose conection at the battery terminal, or a faulty ground.

go to CF and look up the Column Lock Bypass. Same thing can happen.

A Column Lock failure does not cause everything to go dead as described above.

When mine locked up it just said "Service Column Lock" but the car started and drove fine. Then I just installed the Column Lock Bypass module and the warning disapeared. I was fortunate enough to have mine break in the OPEN position so I did not have a locked steering wheel.
