I'm sure the sound you're referring to is the ECU clicking off. Is it it click that happens about 10 seconds after you turn the ignition off/pull the key? If so, it is just the ECU.

Listen to Frank, check for spark using his method. But the first thing I'd do is check the computer for codes!!! It'll even tell you if the ECU itself is toast or not. Go here for the guide on doing this - all it takes is a simple analog multimeter which is only $10 at your nearest Wal-mart, etc.

Do those things & then report back here...
