There are several problems that can cause this behavior, Is it cold where you are? If so the geo's have a known issue with starting in cold weather.
If not then here is a list of possible issues
1.) Cracked or damaged ignition coil and/or primary wire.
2.) Fuel Pump.
3.) Clogged fuel injectors (Engine will run rough when it does run if this is the case)
4.) Badly worn spark plugs, Spark Plug wires, Distributor cap and/or rotor.
*** WARNING *** Your ignition system contains dangerous voltage levels
that could seriously injure or kill anyone coming into contact with the
spark. Be sure to use insulated pliers or a spark tester and follow the
instructions. Failure to do so could cause serious injury or death.
Tests to confirm:
1.) Purchase a spark tester from your local auto parts store, Connect a spark plug wire to the tester and connect the tester as described in its documentation, Have a friend crank your engine and watch for a bright blue spark, The spark should happen frequently and with a rythm, If it seems to skip alot proceed to test #4. If you dont see a spark at all the ignition coil is to blame, Even if you do see a spark, It should be bright blue and clearly visible in daylight, If it is then your ignition coil is doing its job.
2.) Get a pressure gague and hook it up to the fuel line, Turn the key off and on several times (Dont start the engine) if the pressure doesn't rise when the key is turned to on, Your fuel pump may be faulty, Even if it does rise it should reach 15 PSI, If it doesnt then replace the fuel pump and fuel pressure regulator.
3.) You would have to remove the injectors. I recommend you have a mechanic check to see if this is the problem.
4.) Remove the distributor cap and check the rotor for carbon tracking (A black line on the end that touches the cap) if you see that, Replace the cap and rotor and try test #1 again. If the rotor and cap are in good condition, reinstall them.
