Would anyone happen to have a clue as to why a transducer would suddenly start reading 3 volts instead of 5 volts on Power logger? I question Bob Baily of this issue and he told me that my transducer had gone bad. So yesterday I put another brand new transducer on my car and still having the same issue. Fuel pressure is showing in the 70 lbs range at idle with a little under 3 volts. My fuel pressure has been verified with an accurate gauge to be 37 lbs at idle. I've checked ground 12 volt source and signal wires. All are good. So where do I go from here?
