RE: 2002 1.9 TDI beetle wont start
First do the obvious, check all the fuses. This means the oneson the left side ofthe dash and the ones on top of the battery. If they are all good then go to the following steps. Two things you can check are the glow plugs and thefuel delivery system. Put a VTM on one of the plugs and turn the ignition on to see if there is current to light the plugs for start. Do this for each plug. If they have current then disconnect each one and check for continunity. You should get a solid ground for each one. If they check out go to the fuel delivery system.First clean the area around the number one fuel injector line fitting. Then lossen the fitting one half turn. Put a towel around the fitting to catch the fuel and crank the engine. If a steady stream of fuel is noted the delivery system is working.Hope this will help you get started on finding the problem.
