The 5v reference for the fuel rail pressure sensor also feeds the cam sensor, crankcase breather pressure sensor, and intake air temp/pressure sensor, so a chaffed wiring harness to any one of the those sensors could cause problems too. In my experience the issue is usually at the fuel rail pressure sensor, but the engines I work on also have the gear case at the opposite end of the block lol.
