Can low fuel cause P0087?
The check engine light on your dashboard is the most common symptom of code P0087. This code means that the fuel pressure is too low. After this light is on, you may not be able to pass an emissions inspection because a low fuel pressure can cause your car to emit higher pollution levels.
P0087 can lead to serious drivability issues. If the vehicle starts running poorly and having misfires it must be diagnosed ASAP to ensure safe driving. If the fuel pump is failing or the fuel filter becomes completely clogged, this may cause the engine to die while driving resulting in serious issues for the driver.

Will a fuel pressure regulator cause a no start?
A bad fuel pressure regulator can create a difficult to start or ‘no start’ engine. If the ECU can’t measure the excess fuel coming through the fuel pressure regulator vacuum line, it will usually cause the engine to run rich (too much fuel).

What happens if you drive with low fuel pressure?
Decreased Fuel Pressure
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure. Bring your vehicle to HEART Certified Auto Care and let us take a look at that pump.
What causes low pressure in fuel rail?
Three of the most common causes of heavy equipment low fuel pressure are a faulty regulator, a fuel pump malfunction or problems with the fuel lines.
It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the computer, which then uses it to make adjustments to the vehicle’s fuel and timing. When the sensor has an issue it can cause problems with the performance of the vehicle.
What controls the fuel rail pressure?
The pump maintains the rail pressure by continuously delivering fuel to the common rail. This pressure is monitored by a pressure sensor and the difference between the nominal rail pressure value and the measured one is the input signal for the controller.
What are the symptoms of a stuck fuel pressure regulator?
The most common symptoms of a bad fuel pressure regulator include:
Engine Performance Problems. A faulty fuel pressure regulator can cause a loss of fuel pressure.
Illuminated Check Engine Light.
Black Smoke From the Tailpipe.
Fuel In the Regulator’s Vacuum Line.
Vehicle Cranks But Doesn’t Start.
What happens if a fuel pressure regulator is stuck closed?
When the fuel pressure regulator gets stuck closed, it will cause more than needed fuel to enter the combustion chambers. The combustion of too-rich fuel results in black smoke which is released through the exhaust pipe.

Symptoms of Regulator Failure
If you have a regulator and it fails, you’ll notice an immediate reaction in your home. For instance, you’ll experience irregular water pressure that is hard to control with your sink, toilet, or bathtub faucets. The pressure is likely too high or too low.
