P0087 on Chevrolet
Fuel Rail/System Pressure - Too Low
P0087 on Chevrolet vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 5 Chevrolet models — most commonly on Cobalt, Equinox, Express. This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. Typical repair costs on Chevrolet range from $300 to $12,000, depending on the specific model and root cause.
Common Causes of P0087
- •Clogged or dirty fuel filter
- •Weak or failing fuel pump (lift pump or high-pressure pump)
- •Faulty fuel pressure regulator or control valve
- •Restricted or leaking fuel lines
- •Faulty fuel pressure sensor
- •Air in the fuel system or running low on fuel
- •Worn high-pressure pump (direct injection/diesel)
P0087 on Chevrolet by Model
Chevrolet Cobalt(1 issue)
- Fuel Pump Module Failure Causing Stalling and No-Start2005-2010
The in-tank fuel pump assembly is prone to failure, often due to deteriorating fuel pump wiring harness connections or internal pump motor wear. Symptoms appear gradually with intermittent stalling before complete failure. Hot weather exacerbates the problem as heat-soaked pumps lose pressure.
Chevrolet Equinox(1 issue)
- Fuel Pump Module Failure Causing Engine Stall2021-2022
The fuel pump module fails to consistently provide adequate fuel flow to the engine, causing potential stalling while driving. This creates a significant safety hazard as the engine can stall unexpectedly in traffic. GM issued recall N222372310 affecting 23,164 vehicles.
Chevrolet Express(1 issue)
- Fuel Pump Module Failure2003-2022
In-tank fuel pump fails causing stalling, hard starts, and no-start conditions. Often fails without warning on high-mileage vans.
Chevrolet Silverado 1500(1 issue)
- Fuel Pump Module Failure2019-2022
The fuel pump module can fail, causing hard starting, stalling, or no-start conditions. GM issued a recall for certain vehicles due to fuel pump issues. The fuel tank assembly design may contribute to pump failures.
Chevrolet Silverado 2500HD(1 issue)
- CP4 High-Pressure Fuel Pump Failure (LML/LGH Duramax)2011-2016
The 2011-2016 Duramax 6.6L diesel uses a Bosch CP4.2 high-pressure fuel injection pump that is prone to catastrophic self-destruction. The CP4 has tight internal tolerances and is not designed for the lower lubricity of American diesel fuel (compared to European diesel). When the pump fails, it sends metallic debris through the entire high-pressure fuel system, contaminating the fuel rails, injectors, and fuel lines. A single CP4 failure typically destroys $8,000-$12,000 worth of fuel system components.
