If your car won't start even though the starter motor turns as normal but does not fire up

• First check your fuel level, do you need to refill?
• Open your bonnet and check for any moisture on the electrical system, HT leads, distributor cap battery terminals are secure etc.  Wipe off any obvious dampness with a dry cloth.  Spray a water-repelant aerosol product (i.e. WD40) on ignition and fuel system electrical connectors.
• Check the condition of the battery connectors and that they are secure, check that the spark plug HT leads are securely connected (you can do this by pushing them onto the ignition coil).  Check that the wiring connectors are securely connected to the ignition coil.
• Check that the throttle position sensor wiring plug is securely connected.  Check that the fuel cut off switch has not been activated.
