I have a 2008 aveo LT and the car just quit on me the car turns over but it do not strat with no key in the ignition all the lights in the dash are on and the cluster needles going up and down the car is going crazy lol WHAT DO I DO I put a scan tool on it and the car powers it off and on fast like the power is surging off and on fast if I put the brack peddle down it's stop the power lights go out under the hood the fuse box clicks off and on and I the the thottle body going off and on
Has anything been done recently - any repairs or maintenance? Have you put a multi-meter (or better yet a battery tester) on the battery to check the voltage before, and while it's cranking?
Wow. Sounds like your car is celebrating Hallowe'en early by being "posessed". :(Quote:

Sorry... not helpful.
I have seen this, but only when I had left the ground bolt under the battery loose on accident, and the ground was 'sort of' making contact. Or could be the battery going out. Either way seems like a main power issue to see everything cycle on and off.
All take a look at all the grounds see if there all making contact I have a new battery I hope it's not the ECU
I agree on main power source problem. But doubt it's a battery. Fuses and relays stop the batterys' power from reaching the systems to turn them off and on
My Aveo is older than yours, so not familiar with the electrical setup. Does this one have a large fuse on the positive post? Could be shorting out and not stopping power once the car is shut off. Could also short on startup not allowing the fuel pump to run?
Why would the ECU be bad? Were there any symptoms leading up to this point? or just died cold as you were driving.?
bad grounds are 10/1 it seems, do the free stuff before eating the cost of an ECU. if you can.
Not to bring back the dead, but did you ever find what the problem was? I’m haveing the exact same problem with my 2007 LT
The gauges, on 2010 model, can go crazy for 5-10 seconds if battery is dead.
This the gauges are going crazy and relays are clicking With the key out. If I put the key in and turn it, the noise stops. Car will crank. But there is no fuel to the fuel rail. The fuel pump won’t turn on. This all started with what I thought was a bad alternator, it killed the battery. So I charged the battery because I just need to get the car home, it’s stuck at work and they are unhappy about it being left on the property. I really have trouble believing the alternator and the fuel pump went bad at the same time. Why would power be going to the relays with the key out?
Did the charging light come on? If not, there's no reason to think the alt is bad.Quote:

check the fuse and relay firstQuote:
