Hi All, I'm in the following situation, I just had a bunch of parts fitted to the car, here's a list of it: - Roush CAI (PN: 403913) - Ford racing throttle body (PN: M-9926-3V) - Brenspeed Detroit Rockers for FI - Ford racing rocker and lashes - 2.57in M90 supercharger pulley - Larger idler pulley - BBK long tube headers - BBK high flow X-Pypes (will have electronic cutout valves just before the cats) - Walbro 400LPH fuel pump (PN: TU281HP-2) The car was running fine and the tune has been working well for a little while now. Tune has been done by Lito. I stopped the car for about 2-3min and shutoff the engine, when I started it again the engine light was on and my aftermarket fuel pressure gauge was reading (100+ psi), the gauge is mounted on the fuel rail. I used the SCT to read and clear the codes but they come back. Before I even crack the engine the fuel pressure gauge is already reading off the clock. The codes I get are the following: P0191 P0600 P1237 P2105 U0300 Checked the fuel pressure regulator connector and it is fine. So, questions are: - What could be causing it? - What should I check? - Is it safe to even start it? Thanks in advance.
