I checked through numerous threads and haven't found an answer so here goes;

2004 less than 50k on engine, in storage since November, battery out. When I went to start it I got no electrical power , no buzzers, no warning lights nothing; battery checked everything okay with it only 1 year old in June. So I put the battery charger on (Battery Tender) and the lights blink, horn sounds just like an emergency situation and I still couldn't get the starter to turn over. Pegged the gauges only item I could see. I rechecked everything at least twice and have no idea what is going on. If the starter I still should have power for warning lights etc, all connections are clean and tight. Need help one this one.

 

Sounds like a completely dead battery if your starter won't even attempt to start over. I'd be careful starting the car with that battery even if it does turn the starter because you're most likely going to flood.
Buy a new battery!

 

The battery is fine, it turned over my 95 Firebird Formula, not an issue and I stated it was only a year old, with a full charge and this doesn't explain why the horn and lights blink when a charger is put on it. This car has used the charger before and this is a a very light charging unit.

 

In that case you may have either a blown fuse or a short somewhere. If the battery is "good" the starter should turn over.

 

Sounds like a poor connection problem.
