Delphi Fuel Injection Pressure Regulator P/N:FP10494
Delphi FP10385 fuel injection pressure regulator for the 2003-2006 Saab 9-3 and other vehicles regulates fuel pressure in the injection system.
Hard starting, a rough idle or poor fuel economy can mean fuel pressure is off. Before you replace the regulator, rule out a clogged fuel filter, a weak fuel pump or a leaking injector, since those also affect pressure. The fitment lists one regulator per vehicle.
The 2003-2006 Saab 9-3, the 1998-2003 Jaguar Vanden Plas V8 4.0L and the 1998-2003 Jaguar XJ8 V8 4.0L take this regulator, and so do many other vehicles.

Is the Delphi FP10385 right for a 2003-2006 Saab 9-3?

Will this fuel pressure regulator make audible noise?
No. The regulator is made for quiet operation, with no audible regulator noise.
Are the diaphragms in this Delphi fuel injection pressure regulator ethanol-resistant?
Yes. The Nitrile™ diaphragms resist high-ethanol fuels, and the diaphragm materials suit a wide range of fuels.
What are the signs of a failing Delphi FP10385 fuel pressure regulator?
Hard starting, a rough idle or poor fuel economy can point to a fuel pressure problem, though other parts can cause them too. A shop can test fuel pressure with a gauge, since that test needs the engine running.
Does the Delphi FP10385 cross to 800-584?
Yes. Delphi FP10385 is listed as a replacement for 800-584.
