Hi Lynne and welcome to the club.

So that a more specific reply can be given can you let us know what model you have ?? Diesel ?? Petrol ??
If Petrol what engine - 1.8 ? 2.00 V6 ?? 2.5 V6.
Automatic or manual ? How old is the car and mileage.

EAch model can have different likely causes of non starting.

However one thing common to all is the battery. If the car is over six years old and is on the original battery then its on borrowed time.

Did you notice if the headlights flashed when you tried to start the car and failed ?? The cars computer (ECU) checks the battery power level every time before starting the car. If there is not enough in the battery the ECU will not allow the starting proceedure to continue and to let you know this will get the headlights to flash at least 3 times.

If this is the case and the battery is over six years old then it could be new battery time. If the battery is fairly new then it could be that you do a lot of short journies which has not given the battery enough time to recharge properly. Think it takes about 5 to 10 miles of running to replace the energy of ONE COLD start. A decent long run (once the car is running) or useing a battery charger every now and again might cure things.
