Hi guys, I have a 2000 mod Golf 1,9 Tdi Syncro which has been running perfectly during the last few years. But lately it has got some issues... When you turn on the ignition and your going to start it it will normaly start perfectly but now and then this is not the case. Like again today, turning on the ignition and going to crank the engine you can try over and over and you will crank the engine on the started but its totaly dead and will not fire.... What you do hear when you put on the ignition is an electrical motor/pump sound that is coming from the rear of the car that start to run and will continue to run. As fare as I know this is a pumpe that is placed in the tank due to the shape of the syncro tank and is there to even out the fuel level in tank. Anyway,, after maybe 20-30 times with turning ignition on and off you might hear that the electrical motor/pump will stop like it has build up a pressure and then if you try to start the engine will run like ever before. So question is should this electrical motor/pump that I hear which I think is the one in the tank actually have something to do with the car not starting, this is not a supply pump for the engine since this is a 90 Hp engine and not a PD engine. Fuel filter has been replaced to see if that would sort the problem but no luck there, and there is fuel in the lines, and the fuel tank is ful of diesel too. And one big thing is that this comes and goes, so its tricky to find were the main problem is....... anybody have an idea of what to do here..... . Thank you in advance.
