Hi all. Been going around in circles with this one. Was driving the car and it suddenly lost power and came to stop. Engine will crank but not start. Scanned with VCDS no fault codes.
MVB on fuel pressure actual is 0bar.
I can get the tank pump to run on an output test but it will not run upon turning the key.
I'm overthinking it now and would be grateful if anyone has any suggestions.
Thank you

Look at the MVB for RPM whilst you are cranking it over, it should be circa 280rpm.

If the fuel pressure sensor is not being energised by the ecu switched earth then all fuel goes strait back to the fuel tank hense o pressure The switched is at ecu pin no b60 Check it out The way common rail systems work
