A fuel pressure sensor lets the computer know if the fuel pressure has not created any pressure during cranking operation.
How does a fuel pump work in a car?
The pump that delivers fuel to the engine while the engine is running requires electricity in order to operate. This electricity is created by an oil pressure device in the engine. Until oil pressure is created and in turn generates electricity to run the fuel pump, the pump cannot provide fuel to the car’s engine.
