What causes a VW Golf not to start?
Usually, when your car doesn’t start, it’s because your battery is dead. When your vehicle is running, the alternator charges the battery. The electrical components (radio, dome light, lighted vanity mirror) being left on or a loose wire can cause your battery to die. Dead or Dying Battery The battery is one of the most likely causes of a car that won’t start but clicks rapidly. If your car battery is dead, damaged, or old, it may not turn the starter motor enough to get your engine going. But it can provide enough power for the solenoid to generate that clicking you hear.If your engine refuses to start and your ignition continues to click over without any success, you may be able to blame it on a faulty crankshaft position sensor. Without it, your engine will have trouble knowing when to fire the spark plugs or even inject fuel, so good luck getting things started!If your engine refuses to start and your ignition continues to click over without any success, you may be able to blame it on a faulty crankshaft position sensor. Without it, your engine will have trouble knowing when to fire the spark plugs or even inject fuel, so good luck getting things started!One potential reason for your car not starting, despite cranking, could be a blown fuse for the ignition switch.

Why is my car turning over but not starting?
What are the most common causes for a car to crank but fail to start? The most common causes include a faulty fuel pump, clogged fuel injectors, bad spark plugs, low engine compression, or a malfunctioning crankshaft position sensor. Symptoms of a Faulty Crankshaft Position Sensor: Intermittent stalling – The engine may cut out while driving. No spark – If the ECU can’t read the crankshaft’s position, it won’t send spark signals. Long crank times – Your engine may take longer to start, or it may not start at all.Starting a vehicle with a bad crankshaft sensor can be risky and it’s unlikely to work. Disconnect the damaged sensor and try spraying a little starter fluid in the throttle body on your engine. Then, try cranking the engine to start the vehicle.If the air entering the engine is not properly filtered or metered, those mis-readings cause the engine control module (ECM) to inject the improper amount of fuel—once the engine starts. However, a malfunctioning mass air flow (MAF) sensor or clogged air filter can cause a crank no start condition.If your engine refuses to start and your ignition continues to click over without any success, you may be able to blame it on a faulty crankshaft position sensor. Without it, your engine will have trouble knowing when to fire the spark plugs or even inject fuel, so good luck getting things started!First, Check the Basics – The very first step to diagnose a “cranks but won’t start” problem is to find if something’s missing – Spark, Fuel and Compression (which includes cam timing). These three things are required for an engine to start.
