2008 Cayenne Turbo- I changed both pumps and fuel filter. I started it up and it ran great then drove around all evening. Later in the evening I noticed it was cranking a bit when starting, a bit alarming! So I decided to put 10 gal gas in, ran fine but still cranked for a bit. The next morning I decide to fill the tank all the way and immediately it had a hard time starting then, when it started it ran for about 10 seconds then dies. Later I pulled fuse #13 out and car runs fine so obviously 1 pump is flooding out. So frustrated please if any one knows what to do next please help. Thanks!
