1999 Plymouth Voyager Espresso

[jojo7211]

Won't start. Sounded like a dead battery, but all electrical inside vehicle worked.
Subsequently all dash lights went off except the ABS, oil light, and parking lights. None would go off even with key out of the ignition. After several tries, and the same thing happening, there was a ticking sound for about 5 minutes. Then all lights went off. Still no start. Any ideas?

I have a dozen ideas but I think we need more info to work with.

Does the car have a remote start system?
Does the car have anti-theft? (factory or otherwise)
Does the car have auto head lights?
Has there been any recent work done?
What exactly is the battery voltage at rest, with the key on, when you try to crank?
Where does that clicking sound come from?
Are you sure the dash lights that stayed on with the key removed were ABS and oil?
What engine, trany, trim level?
How many miles on the car?
