I got nailed this morning - without any warning my car won't start,
sounded as though it went bad when I turned the key to Start. If I turn
the radio ON, I get "code" displayed (this was before I disconnected the
battery). When I turn the key to ON (II) I get a chirp like what my
computer makes when I plug in a USB device with Windows running. Another
chirp when I turn to Start (III) - no starter solenoid clicking, no fuel
pump sound, completely quiet except for 6 beeps (as though the car
wasn't running and I opened the driver's door with the key in the
ignition). I tried my other key, which made no difference. The + post on
my battery was badly corroded (why do they cover that thing up?), so I
neutralized it and cleaned both terminals. The ground strap is tight to
the body.

Are we talking main relay here?

Car is 4 cyls w/5 speed AT. I live in the NYC area and don't drive it
daily. It gets regular oil & filter changes, etc.

Suggestions or advice?

TIA
