Gotta hold your computer closer to the car so we can diagnose the problem.
Have you checked anything yet? Is it out of gas? Does it have spark? Does it even crank? What other observations can you provide? Are the interior lights bright or dim? We need a clue where to start. Battery could be run down due to a dead alternator. Camshaft position sensor or crankshaft position sensor could have failed. Those will cause a crank, but no-start condition and there won't be any spark. If a sensor failed there may be a diagnostic fault code stored in the Engine Computer. Having those codes read will indicate the circuit or system that needs further diagnosis.
