1999 Oldsmobile Alero 99 Alero won't start HELP please

99 alero. Yesterday the car wouldn't start. When you turn the key to the on position, the headlights flash, gauges seem to bounce around and the seat belt and service engine light flicker. I can hear the fuel pump load up. When you turn the key to start it, everything goes dead. Is this a passlock problem or some sort of short in the bcm? The security light was flashing for a little while, but now its not. The engine is a 3400 and the battery is at 12.47 volts. I tried jumping across the starter. Minor sparks. There is no clicking at the solenoid when the key is turned. Today what it does is when you to the key to start it nothing happens, but when I shut the key off the gas, tach, speedometer and temp gauges all jump as high as they can go for 3 seconds and then go back to normal. If I put my battery charger directly to the starter and turn the key it will crank over but not start and all of the lights and everything works just fine so I don't think it is the ignition switch. I have power to the fuse box under the hood but not to the inside fuses. The courtesy lights work on the floor but not the dome light
