Robbie's got you on the right track if a fully charged battery won't make the starter operate. If the engine will turn with the starter, then try the ignition module. A common problem with the V6 is the ignition module inside the distributor. To test it to see if the engine is 'getting power', remove one of the spark plug wires, insert a sparkplug into the rubber boot and hold the metal side of it against the dogbone bracket. Have a helper try to start the car. You should see spark from the plug. An absence of spark will generally be the ignition module. Advance and AutoZone sell them for around $40 with a lifetime warranty.
If you are getting a spark from the plug, remove the long rubber intake tube on the left side of the manifold. You can use some WD40 to spray a shot inside the throttle body while having a helper try to start the engine. If it fires, then you likely have a fuel pump problem or a pump relay problem.
First thing to do, though is to check all your fuses underneath the left side of the instrument panel.
