If it is turning over, but won't start, then it is usually a blown fuel injector fuse or a blown ignition coil. It is also possible that because of it's age it may need a new fuel injection pump. If it's getting fuel and spark and still not starting, then it might be a bad timing belt. Which engine is in this car??? 2.8L?? How many miles??Age affects all cars in different ways.I wish I were there to offer it a little experienced loving care, that car will last another 10 years!!
