The fuel pressure regulator controls the fuel pressure in your Ford’s fuel system, maintaining the proper pressure needed for your vehicle to run optimally. If the fuel pressure regulator malfunctions or fails completely, one or more symptoms will occur. While testing will need to be performed to verify the failure, if any of these symptoms are present, a faulty fuel pressure regulator may be to blame.
Slow or No Start
Part of the fuel pressure regulator’s job is to maintain fuel pressure at the fuel injectors at all times, including when the engine is shut off. A fuel injected vehicle, with proper fuel pressure, will start up quickly, if no other malfunctions are occurring. In the event your Ford cranks easily, but doesn’t start within the first five or six revolutions of the starter motor, you may have a faulty fuel pressure regulator. If the regulator has failed completely, the vehicle will crank, but not start at all. Avoid cranking the starter for too long, or you will burn it up and add the starter to your list of needed parts.
