Beeping when I start my 2002 Jeep Liberty Sport

Sounds like you need to have your alternator checked.

Have you tried to jump started ? If your jeep starts when giving it a jump, you may have a bad battery. Check fuses for fuel and ignition systems. If your battery is bad, could be because the alternator is not charging it. Might want to have this component tested.

Mark, Check the links to the forums a lot of jeep owners have this beeping issue, they are saying could be anything from a bulb out, blinker left on too long to seat belt not on while driving.

timeing chain

These are common for the instument clusters to go bad. There are places that can rebuild it or you may have to replace it all together. There is a self test you can run by: key off, push and hold odometer/trip button and then turn the key on while holding the button *don't start it though*, then release the button and it will automatically start the self test. It will show a series of digits and then the software version #. After 5 beep tones it will automatically exit the self test mode. During the test, you can observe the speedo and fuel gauges to see if they are working.

battery? a short?

Check your connectors to be sure they are all plugged in thoroughly.

I have an 2002 Liberty had the same/similiar problems, have the dealer check the wire harness that runs underneath the driver's seat, my wires had gotten wet from somehow and it caused the wires to corrode, they had to replace sections of the wire harness to fix the problem.
