engine does not start
well your either not getting fuel or spark or your anti-theft can kill both. do you have any security lights on your dash, are you using your proper key?. the first thing i would check is have someone listen down near your fuel tank as you are in your vehicle, turn your key to the on position (dont try and start it) the person listening should hear the pump kick on and make a humm sound. if they dont hear it turn the key off wait a minute or 2 and try again. if your fuel pump is not kicking on thats your problem. (not always the pump though could be as simple as a fuel pump relay or a bad connection to the fuel pump)
zak3nn3dy has a very good point. Also it could be a weak (though not dead )battery or alternator may not be charging properly. Then the crankshaft sensor being bad is another possibility . So dont just throw parts at it. Try to investigate the various parts of the fuel and electrical systems and see if you can pin it down.
use remotconrol to lock the doors and open it then start it.
