How do you fix code 48 fuel fail on a l reg jag automatic?

Answer 1

Code 48 on a Jaguar typically indicates a fuel system issue, often related to the fuel pump or the fuel pressure regulator. To fix this, first, check for any fuel leaks and ensure the fuel pump is functioning correctly by testing its voltage and pressure output. Additionally, inspect the fuel filter for clogs and replace it if necessary. If these components are in good condition, further diagnostics may be needed to check for wiring issues or faults in the engine control module.
