Car doesn't start after fueling

Hi Guys,

My friend has a very weird issue with his car 2004 MK5 VW Golf 1.6 FSI.

Whenever he goes to the get fuel in the car after fueling he gets back in his car and is unable to start it. This issue happens every time he fuels his car without fail.

I done some research online and saw that it may be the EVAP Purge Valve but all the posts that mention this are for GTI models and also when I tried looking for the part I could only find it for the GTI model so I think maybe that it may not be for the FSI model.

Any ideas on what could be causing this issue?

Regards

Sounds like the classical symptoms of a closed loop EFI system that is not holding proper rest pressure on the injector rack. Without adequate pressure on that part of the fuel system the liquid fuel will vaporize and purge the liquid fuel lines with fuel vapors. There is a pressure regulator on the downstream side of the injector rack that is typically the point of failure in a situation like this. You need proper pressure testing equipment to test for this condition both before and after you replace any out of specification/failing part.

Another possibly quicker diagnosis is to turn the ignition from off to on about 10 to 20 times before attempting to turn over the engine with the starter… this action will get the fluid back up to the proximity of the injectors before you attempt to actually start the engine. If this latter suggestion doesn’t work it could be something more involved with the EFI or even electronic ignition system perhaps.
