De-pressurising the Saab 9000 fuel system


Prior to any work that involves opening the fuel system, it is necessary to de-pressurise the system as detailed below.

Time required

Around 5 minutes.


  1. Open the fuse box and remove the fuel pump fuse (fuse 14).

  2. Start the engine (if possible at all) and run until it stalls.

  3. Try to start the engine at least twice more, to ensure the system has de-pressurised.

  4. Once all work on the fuel system has been completed, replace the fuel pump fuse.

  5. Switch on the ignition and check for any fuel leaks.

  6. Allow 10-15 seconds for the fuel pump to re-fill the fuel system before starting the engine.
