Causes and Fixes P0087 Code: Fuel Rail/System Pressure Too Low

How to fix a P0087 engine code: Fuel Rail/System Pressure Too Low
A P0087 code is set when the fuel pressure sensor detects low fuel pressure at the fuel rail.
Many modern vehicles have two fuel pumps: a low-pressure fuel pump (LPFP) in the gas tank and a high-pressure fuel pump (HPFP) bolted to the engine.
Check oil for fuel or metal from damaged components.

Possible Causes of a P0087 Code:
Bad Fuel Pressure Sensor
Clogged Fuel Filter
Bad Low Pressure Fuel Pump (LPFP)
Bad High Pressure Fuel Pump (HPFP)
Bad Cam Follower
Bad Fuel Pressure Regulator
