Do you mean it cranks but won't start?
Check for spark at a spark plug wire. If you have spark, it's probably not the ignition, but a fuel issue. Do you hear the pump come on briefly when key is turned to on? You may need to stand by the gas tank with the cap off, while someone turns the key on. The pump should hum or whirr for about 2 seconds to prime the fuel system. Then it will shut off until car is cranked over. If the pump and the ignition is working, check fuel pressure.
If you had no spark, it could be the coil, or crank position sensor, or...well, you would have to diagnose the ignition system.
If the problem is not cranking over, check all connections at starter and battery for a clean tight connection. Check for power at the starter solenoid when key is held in crank position. If power there, the solenoid must be bad. If no power the circuit from ignition switch to the starter solenoid has a problem ( like the starter relay or the neutral safety switch).
Good luck.

Check the battery for bad connections..take off the cables and clean both the battery posts and the cable connectors and then try...if no start, then see if you can check the battery voltage with a voltmeter...at stand still(engine not running) the battery should read 12.5 volts...if battery is ok, then there is the possibility that the starter solenoid, the starter relay, or (in rare cases) the ignition switch is bad
