Check the plugs to see if there is fire. Check the timing and the cam sensors for proper operation.
crank sensor is bad
It would be helpful if you can explain the " won't start " Does the engine turn? If it turns does not fire? Was it running before?
In most cases, the engine will not fire or start if the clutch switch is bad. The key will turn in the ignition but there will be no turn-over or sound from the engine. If the engine turns over but doesn't start, there might be a problem with the fuel supply.
replace the spark plug wires
If the motor turns over then start by checking for fire at the plugs. Check to make sure that the timing belt is not broken and is working properly. Check the cam and crank sensors for proper operation, as well as proper fuel flow.
