What to check if it wont turn over does nothing
Start at the battery. Check for clean, tight connections. Any chance it is discharged? It needs to be at lest 12.6 volts on a voltmeter to be ready to start the car.
Is there power from battery to the ignition switch? Turn key on. Do warning lights and gauges come on? And accessories work? Then there is power to the switch. If nothing, start checking fuses and fusible links that pass power from battery to the switch.
An electrical circuit is a complete electrical path from a power source to an electrical load to ground, and back to the power source-the battery. The starting circuit is just such a circuit. From the battery to the key switch to a relay or switch (neutral safety switch) or two, to the starter, and then to ground-back to the battery. If the key turns power on, one could next see if power is getting to the starter solenoid, mounted on the starter. The small wire to the solenoid should have power to it when the key is held in crank position. Use a test light or voltmeter to check for power there. If has power, likely the starter or solenoid is bad. You then need to take it off and have it tested-a free service at most parts stores. If no power is getting to the solenoid, but the ignition switch has power, further testing of the start circuit will have to be done -the clutch switch (or neutral/park switch if automatic trans.), the starter relay, and whatever else is in your starting circuit.
If car has an alarm system, make sure it is not activated, so the immobilizer function is not causing a no start.
Good luck. Post back with results.
