Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
We may have a problem with the fuel pump driver module which is built into the Rear Electronics Module. It is located in the trunk behind the passenger side. We should check the connections there to mak sure they are clean and secure. It also could be the wiring going to the REM from the ECM. We will need to check fuel pressure at the rail to be sure. If a new or used REM is installed it must be programmed unfortunately.
