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.
What happens if fuel pressure is too low?
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.
Can you drive with P0087?
Code P0087 is a moderately serious code that can cause severe drivability issues if ignored. Most mechanics advise against driving with an active P0087 code. If you encounter a bad fuel pump or the fuel filter becomes completely clogged, this may cause the engine to die and lead to costly repairs.
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.
What causes a P0087?
Trouble Code: P0087 Fuel Rail/System Pressure – Too Low
There is a sensor on the fuel rail that monitors fuel pressure and determines if the vehicle needs more or less fuel. When your vehicle’s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification.
Can driving with low fuel damage car?
Low Fuel Levels Can Damage Your Engine
Driving on low fuel levels also makes it possible for particles and debris to damage your engine or fuel pump. If there are any pieces of dirt in your fuel, they will settle at the bottom of the tank and are much more likely to end up in your fuel pump if your fuel levels are low.

In the city, you can use less fuel by easing onto the accelerator pedal gently. To be as fuel-efficient as possible, take 5 seconds to accelerate your vehicle up to 20 kilometres per hour from a stop. Imagine an open cup of coffee on the dashboard.
How long does a low pressure fuel pump last?
The fuel pump is your vehicle’s unsung hero. It takes gas from the gas tank and sends it to the engine so your car, truck, or SUV can start and run. Your vehicle’s fuel pump should last at least 100,000 miles or more.
How do you check a low pressure fuel pump?
Start the car and let it idle. Install a fuel pressure gauge, run the pump, and note the pressure reading.Then compare it to the manufacturer’s specification. If the pressure is low, you should address that problem.
What are the signs your fuel pump is going out?
A bad fuel pump may overheat and inadequately deliver gas to the engine, causing it to run hot and turn off while on the road. In this scenario, your vehicle may start back up after overheating and shutting down, only to do the same thing a half-hour later. This scenario is a common sign of a bad fuel pump.
How much does it cost to replace a low pressure fuel pump?
The average cost for a fuel pump replacement is between $220 and $1,062, depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.
Fuel pump failures tend to be sudden and unpredictable, with few symptoms to warn the motorist that trouble is brewing. And the higher the mileage on the vehicle, the greater the risk of a fuel pump failure.
How do you unclog a fuel pump?
If your vehicle has an electric fuel pump, you can use a fuel system cleaner to clear any sediment buildup or blockage. If you have a manual one (usually found in older model vehicles), you can actually open the pump to clear debris out of its internal filter, though that isn’t an option in most modern vehicles.
How do I reset my fuel pump?
