2004 Audi A6 wont start. need some help.
I have a 2004 Audi A6 Quattro 2.7t and it will not start. I have already tried changing the fuel pump, fuel filter, fuel pump relay, and the fuse is good. I do have spark, so that leads me to think the problem is somewhere in this area. The day before it wouldn't start it was running perfectly fine with no issues at all. Then the next morning I went to start it and it fired up for a split second then died.... open to any ideas that might work. thanks.

Take your fuel line off under the hood, see if the gas physically prime. 17m wrench should do it. If your sure you got spark it's most likely a fuel issue. Your crank senor should be working if your positive there's spark.

Hi, I've got the same problem with my 2002 A6 2.5 TDI Quattro. Did you manage to get your A6 starting? We've had the fuel pump off and tested and all ok with it. We're looking for an ECU Pin Data wiring diagram to check the continuity between the ECU and fuel pump but haven't found one yet. Regards.
