hello first time posting here and I appreciate any help that is giving to me thanks.
my GF has a 2006 golf tdi its the old body style not the newer one. She was driving for over 300kms no problem then we stopped to change drivers without stopping the engine I got in drove for maybe 2 kms and it died.
it cranks fine glow plugs lights are on but no fire.

If I put my head by the lift pump under the rear passenger seat I can hear it very lightly.

I checked for codes only ones were glow plugs #4 were bad but that I already knew.

if relay 109 was bad I wouldn't have the glow plug light on right ?
with my lift pump being on it should be filling up my fuel filter but I took the plastic "T" off from the top the filter and I couldn't see any fuel in the filter.


I tried boosting it last night since I read that VW don't like low voltage from the battery and I have 12.06 V still no start im on a bum here

Pull the line from the tank and see if it pumps fuel when the key is on.
I hear my lift pump from the driver seat as soon as I turn the key.

ok thanks eddieleephd I did that and no fuel came out I proceeded to test for voltage at my plug and no voltage anywhere with the key on so Im guessing pump is still good but not getting power. I am getting 0.2V at the purple wire is there anywhere on this website for wiring schematics ?

Not so much wiring schematics here, sorry. Everyone loves to send people after the Bentley.
Check your fuses, and check neutral to ground to be sure you can get a good ground.

all fuses are good by the door and my neutral to ground is good the only relay that controls the transfer pump is 109 ?
