Changed the fuel filter, car won't start...any ideas? I have been cranking it and cranking it and don't want to wear out the starter. This is for a 2001 golf tdi 5 speed.
Get a vacuum pump and hook to return line rubber hose at filter then pump until diesel goes into cup with no bubbles. If you continue to get bubbles then the return line little hoses between the injectors all the way back to pump need to be changed. then vac pump again. also be sure return fitting at pump connection is tight, if no bubbles, your pump is fully primed and car should run. Cant start when fuel bleeds back from pump. I just had this same mystifying problem and return hoses were leaking. When replaced car fired up and ran normally.Changed the fuel filter, car won't start...any ideas? I have been cranking it and cranking it and don't want to wear out the starter.
