SOURCE: hesitates when pushed down on throttle, hard to start, wants to die
Check your cat converter.
SOURCE: engine wont turn over with key, not getting enough gas to run.
Have the key and ignition checked! I am assuming that the key has a security chip on it, Right? If so, re-program key at dealership, and if that alone doesn't work, have them check both the key and column.

Change the IAC the idle air control. You may be able to clean it and put it back on.
SOURCE: short circuit in fuel pump electrical circuit
Sounds like a dead short in the wiring somewhere. Follow the wires from the pump forward and look for any chafed wires.

if you are not hearing the buzz the fuel pump is not engaging if you have a test light or a power probe test the power wire going to the pump using the "quick connect" if you have power going in to the pump and have no noise the pump is bad. If you don't have power then test the fuel pump relay and fuse. an easy test is to pull the relay located under the hood and switch with one of the ones next to it turn the key and listen for the pump if you have no noise the relay is more than likely ok check the fuse. To test the fuse use the test light because you can't always see a broken fuse and you want to see if you have power coming in. check all the connections listed above for corrosion and improper space between terminals If I was a betting man I would go with a bad fuel pump judging on the year I assume it has quite a few miles and fuel pumps burn out with use. any time you replace a fuel pump you should replace the fuel filter. this filter almost never gets changed and tends to rust so make sure you have plenty of penetrating oil handy. do not use heat obviously.
