I have a 1995 audi a6 2.8 and as of last night the car will not start after driving for less then 5 mins. It's my daily driver ran fine up til last night b4 work. My guess is my fuel pump went out cause it's cranking and has power yet it won't kick over! I was going to attempt starter fluid, until I ran into the black box that runs the hose to my air filter box.. And it has my breather hoses connected to it also. So my question is can I spray directly into that or is my intake manifold located elsewhere

 

Don't use easy start!

If it was running fine then just stopped, easy start won't fix it.

When you're turning it over, if everything sounds like it used to and sounds like it wants to fire or just turns over then there's a pretty good chance it's the fuel pump.

You'll see the fuel rail around the intake housing in the center (silver pipe). There is a pressure regulator on one side and a rubber hose on the other.

If you turn the ignition on, but do not start the motor, this fuel rail should be pressurized.

Myself, being the back yard hack that I am, I would loosen the joint between the hose and the hardline. If it starts to spray, the fuel pump is good. If it merely drips, there's no pressure and they fuel pump isn't working.
