A Fault code in our scan revealed a faulty pump module as the possible cause of the issue.

A new Fuel Pump module (right) is ready for the exchange.
A faulty fuel pump module can upset the performance of your fuel system and causing the engine to starve for fuel under load. Symptoms such as:
1. poor engine performance,
2. hard starting,
3. poor idling,
4. hesitation,
5. stumbling on acceleration,
6. loss of power on high-speed.
