This sounds somewhat similar to a problem I had with my 1999 Saturn SL2. There was "burning and arching" on the fusebox and it was replaced. The first few times my car would make an extra beep noise when locked or unlocked and I believe the radio/clock had to be reset. The problem got worse although sporadic. Eventually the car wouldn't start - not even making a clicking noise and a big variety of electrical components would not work or didn't sound right.

Look where the throttle cable hooks up to the throttle on the throttle body,it is no the opposite side,it moves with the throttle,if this was helpful,please rate,thank you.

Sounds exactly like my 1999 SL2 which had "burning and arching" in the fuse box. Car one day be fine the next I'd take it to the store, come back in 10 minutes and wouldn't start, no radio, no power windows, no keyless entry remote, no rear defrost and even locking doors from inside power buttons it sounded odd. This fixed the problem by replacing the fuse box.

This is probably a faulty fuel pressure regulator. You can rent a tool at most auto part stores that connects to the fuel rail to show you the pressure level. If it is low (less than @40 PSI) or if it fluctuates very much, replace the regulator. It is also a good idea to replace the fuel filter, as it can clog and prevent adequate fuel supply from reaching the engine. You may want to replace the filter first, as it is usually cheaper.

This is a fuel related problem.

Replace the fuel pump.

bad idle air control valve or a misfire,could be alot need more info

it sounds like the car has a passive alarm , you will have to call the dealer and give them the vin# and see if they can sell you a remote to deactivate the alarm.
