Crank no start help.
So I am new to Audi's. I just bought a 2002 A6 2.7T auto all wheel drive. Has 95,000 miles. The car had a check engine light and I was told it had at least two bad coils. So I replaced all the plugs and coils. Car started up and ran great. Drove the car around town several stops (restarted no problem). I parked the car over night and the next morning it would not start. I did check the CTS it is the green one, also it does try to run if I use starting fluid.
1. How do I check the fuel pressure (can't see a Schrader valve on the fuel rail.)
2. Where are fuel pump fuse(s)
3. How do I test the fuel pump and how do I get to it (drop tank?)
I do not have a way to pull codes on this car.
Thanks

Thanks Huskerbob. Here is what I have done. I was able to pull codes with a generic obd2 scanner P0300 (random miss fire). Checked the fuse on the drivers side of the dash #28 it is okay. Found the fuel pump under the rear seat and used a test light to check for power. I only can get power on the green w/yellow stripe (#1 on the plug) only when cranking. So next I removed the fuel line and installed a pressure gauge. Turned the key and did not see any pressure on the guage. Even tried cranking with the hose off and no fuel came out. So I am going to try a new pump. I will update when done. Thanks

It sounds like you have a natural safety switch problem, better yet I would think faulty ignition switch. If the car is having problems shifting out of park or between gears it's a linkage issue .However if the starter is engaging when you use the key then it does see that it is in park if it won't turnover when you try to start it then in your case it doesn't think that you truly are in park therfore your neutral safety switch is preventing you from starting your car. I would look at the ignition switch first especially if the problem is intermittent.
