What Does This Fuel Pump / Fuel Injection Valve Assembly Do?
The fuel pump draws fuel from the tank and delivers it at the correct pressure to the injection system. The fuel injection valve assembly meters and atomises fuel into the combustion chamber at precisely timed intervals commanded by the ECU, ensuring efficient and clean combustion.
Possible Fuel Pump / Fuel Injection Valve Assembly Problem Symptoms
If your machine is showing any of the following, a faulty fuel pump / fuel injection valve assembly may be the cause:
- Hard starting or extended cranking time before the engine fires
- Black smoke from the exhaust under load, indicating over-fuelling or poor atomisation
- Noticeable loss of power and sluggish response under normal working load
- Engine misfiring or running unevenly at idle or during acceleration
