SCV = SUCTION CONTROL VALVE
The suction control valve is the main component that controls the fuel pressure very much like turning your tap on it needs to move smooth and swift which is why replacement can improve performance especially when a compact Type has been used as they are and have found to be often problematic
Not just in Toyota land cruiser in other makes and models of diesels it can cause stalling it can cause blowing smoke it can cause rattles and knocks.
The engine requires the correct fuel pressure for everything to work correctly.
Save money on supply pump replacement because theres likely nothing wrong with it.
