INTERMITTENT LACK OF POWER OR HESITATION
UPON ACCELERATION – RESTRICTED FUEL LINE
Customers may experience an intermittent lack of power or hesitation upon acceleration. The
malfunction indicator lamp may not illuminate or DTC P0087 may be stored (history). This is
possibly due to a restricted low pressure fuel line.
DTC P0087: Fuel Rail/System Pressure – Too Low
Begin by checking the fuel pressure at the low pressure pump fuel output line (A) in the fuel
tank using a fuel gauge kit, tool number: FPG2200. The gauge should display above 71 PSI if
there is no restriction in the low pressure pump. When the lack of power/hesitation occurs and
the fuel pressure at the fuel tank is within specifications, disconnect the fuel pressure gauge
from the low pressure pump and connect it at the high pressure pump fuel feed line (B). When
the lack of power/hesitation occurs and the gauge drops below 71 PSI, the fuel feed line from
the low pressure pump to the high pressure pump may be restricted. Replace the low pressure
fuel line from the tank to the high pressure pump by referring to the “Engine Control / Fuel
System → Fuel Delivery System → Fuel Line → Repair procedures” chapter in the applicable
Shop Manual on KGIS.
