A starter motor plays a very important role in the initial starting of your Vauxhall Vectra. Starter motors often stop working itermitently before packing up completely. Sometimes they sieze up which after a simple tap with a hammer will get it working again for a short while. Even if this gets you started we would still recommend checking for loose connections before ordering a new starter motor. orangespanner have large stocks of starter motors for a wide range of vehicles at great prices ready for fast delivery.
