How I to solve a P1237 Code ?

I would start by making sure the harness was not pinched during the install of the tank. I believe the FPMD is under the rear right seat or on that side, in the trunk.

I previously posted my 2005 Ford Escape Hybrid had a code P0190 . I bought a scan tool and actually have two codes (P0191 and P1237).

- Fuel Pump Secondary Circuit (Fuel Pump Driver Module)
- Low or no fuel
- High fuel pressure
- Low fuel pressure
- Faulty Rail Pressure (FRP) Sensor
- FRP harness is open or shorted
- FRP circuit poor electrical connection
- Faulty Fuel Pump
- Vacuum leaks

P0191 is fuel rail pressure sensor or circuit low input. This indicates that fuel pressure is too low or the sensor is faulty or the circuit is at fault The fuel pressure should be tested to see if it is spec.and circuit test preformed the location of this sensor and testing needed to make an accurate repair requires some degree of skill and someone that is comfortable doing this type of diagnostic repair

I have 2000 Sable 3.0 DOHC with a code P1237. Sometimes the car shuts off by itself, and often it will crank without firing. What's wrong?

Back in the trunk, on the passenger side, is a fuel pump module. The ground for the module was loose.
