If you overfill the gas tank and it goes into the EVAP and into the charcoal canisters can this set off all your warning lights and does it need to be replaced or repaired ($1000) ?

Have check engine codes read. Post them back on here. They will give us clues as to what's going on with it. Does it still drive ok? Is check engine light flashing?

If you can stand the lights being on eventually the evap system will purge itself, you may have a slight running problem for a while. It is somewhat difficult to overfil a fuel tank these days, did you do it with a gas can?

In nearly 50 years of driving I never heard of or ever over filed the gas tank. It's a new one on me.

We didn't fill it. It came to us on a transport with a full tank of gas. we've only put 15 miles on it driving to DMV and to get it "smogged". It had been sitting for 6 months due to a death in the family..... the lights didn't come on until yesterday the 3rd time we drove it.

With it having set for so long all the lights coming on could be due to a loose battery connection, failing alternator or bad battery. This is where I would look first.

6 months is long enough for this garbage they call fuel to start going bad, like dandy stated check the connections for corrosion, it might be a good idea to remove all of the ECM fuses, put a battery charger on it overnight so you have a fully charged battery, put the fuses in and start it up and drive it normally and see if the check engine light turns back on, if it does go to a parts store and have the codes pulled write then down and repost them back here and we can go from there.

I did this once with my '93 Caprice. There was a fuel odor for a few days but nothing was harmed. HTH. -Jim

Drive it. Go around the block on till you feel sure that it's reliable then go for a nice long ride. Like T.S. Said the fuel is probly one step away from varnish.

Try a can of injector cleaner or some such similar product (check at your local auto parts store) it "may" help you get enough energy out of your old gas to use up enough of the tank, so fresh gas can be added at a 1/4 down and more as you use up the current gas.
