Hello and welcome to JustAnswer!

It sounds as if you're setting high and low signal voltage codes for the fuel rail pressure sensor, which would either be the sensor itself or a wiring issue. This would cause the engine to go into limp in but wouldn't cause a misfire. You may have more than one issue going on, especially if you're hearing abnormal engine noise. The noise could be combustion noise from high rail pressure though.

Do you have the P code numbers?
