First, check whether the push rod that drives the diaphragm in the pump mechanism is damaged. Gently block the oil pump's oil inlet with your finger and try to start the engine. If you feel suction at this time
The force can prove that the push rod is intact.
2. If there is no suction sensation at the fingertips, it indicates that the push rod is damaged and the fuel injection pump should be replaced as a whole.
Note: When the electric fuel injection pump is in operation, if it emits a strong sound of fuel injection, it indicates that the pump is in good condition. If there is no such sound, it suggests that the fuel supply pump has malfunctioned.
