Well I decided to do a little troubleshooting. I installed a s4 TII rail from a friend and that rail didn't even hold pressure after the fuel pump was off. Luckily, I was able to get a brand new FPR from work and installed it. It worked! I moved my oil pressure to the fuel rail so I could monitor pressure in the car. Its a 90deg sweep but at least I can gauge movement. I did my mityvac and foot pump test and saw decent movement with the pump running. While driving and in boost I could see movement as well.
Even though its working now, I'm inclined to get a robust aftermarket FPR using the stock s4 rail for reliability. Good idea?
So.... three bad FPRs?
