Would really appreciate a little experience on this one guys. My wife was on the way home in our '04 Ex K-flex V6 and a service soon light came up. She told me the guy at Advance read that it was - "Fuel rail pressure sensorA circuit high input". Now she went to the local Ford dealership and they told her it was an indicator that the fuel pump was on the way out. I'm a little wary that they may just be fishing for the most expensive repair but it could be true. Someone else said they replaced the sensor and then later the fuel pump went out. So is there a voice of experience here who has dealt with this and can give sound advice. The last thing I want is my wife to be stranded somewhere but on the other hand the repair was quoted almost $700. Help! Thanks in advance.
