It's under the hood, on the driver's side, under a square, black box with a lightning symbol on it. Loosen the flower-shaped screw that holds the lid of the box down, remove the lid, flip it upside down and when you look at the inside of the lid, you'll see a map of all your car's fuses. There's also a fuse diagram on the very end of the dash, but it's accessible only when you open the driver's side door. When you're driving, that end of the dash is blocked by the closed door.

Fuel Pressure Regulator
- Removal & Installing
The
fuel pressure regulator is a diaphragm-operated relief valve with fuel
pump pressure on one side and regulator spring pressure and intake
manifold vacuum on the other side. The regulator's function is to
maintain a constant fuel pressure across the injectors at all times.
The pressure regulator compensates for engine load by increasing fuel
pressure as engine vacuum drops.
The fuel pressure regulator is
serviced as a separate component. When servicing the pressure
regulator, make sure that the O-ring back-up, large O-ring, filter
screen and small O-ring are properly positioned on the pressure
regulator.

REMOVAL & INSTALLATION
The need
to work as cleanly as possible cannot be over-emphasized. Even the
smallest amount of dirt, if allowed into the fuel pressure regulator
and/or the fuel rail, will find its way to the fuel injectors. The
nozzle openings of the injectors are very small. Keep hands and tools
clean. Clean the areas to be disconnected with a suitable solvent.
Carefully cover open fittings and connections to keep out foreign
material. Dirt in the injectors almost guarantees a clogged fuel
injector and engine performance problems.
