if it just clicks, check all ur battery connections and make sure they are clean and uncorroded and make sure they are tightened down real good. if it just turns over but is getting spark... check ur fuel by loosening up the test nut/bolt which is located on the very top of the fuel filter, if fuel squirts out... ur good. if not, ur filter may be clogged... also check ur ignition relay in the fuse box under the hood, u can also check ur fuel pump - to do this go sit in you car and turn ur key all the way up but dont start it, you should hear the pump ingauge.
