Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.
Thanks for using FixYa!

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.

MOST LIKELY THE FUEL PUMP PRESSURE CHECK VALVE IS DEFECTIVE, THIS ALLOWS THE FUEL TO DRAIN OUT OF THE LINES AND FILTER AND CAUSES A LONG CRANK TIME/HARD START, THE CHECK VALVE IS PART OF THE FUEL PUMP AND THE FUEL PUMP IS LOCATED INSIDE THE FUEL TANK, THE TANK MUST BE DROPPED TO REPLACE THE PUMP.
