Ok here's the story my wife drove the A6 450 miles away there It's sitting she said thet the emissions light was on and the car and turned over fine and almost started I'm going up there to work on the car next week I'm assuming it's a fuel problem But I'm open to suggestions
Question 1 Do I need to buy a diagnostic tool "hold down recirc and up arrow and select 1deg c"
2 where is the fuel pump relay
3 I'm assuming the pump is in the tank do I need jacks to get to pump?
