P0440 code, Fuel Pressure seems kinda high too? I'm getting a P0440 code. I replaced my stock fuel pump with a walbro 340 intake about 8 months ago and everything has been fine up until about 3 weeks ago when the SES light came on. I tested my fuel pressure and it is at 67 psi at idle and stays the same through the power band. Is the too high of fuel pressure? If thats normal for my setup what else do you think it could be. Any advice is greatly appreciated. Thanks

Sorry for bringing this up from the grav e, but I am intrested in this as well. My fuel pressure reads and stays constant at about 70 PSI and it is getting the reading from the fuel rail. I just bought the car and the seller never mentioned anything about a aftermark pump or injectors.. That seems kinda high to me.
