Fuel Injection System

Unburnt fuel dripping from the exhaust, black smoke, and backfires are just a few symptoms of something wrong with the car's Fuel Injection System. Contaminated fuel is the main cause behind faulty Fuel Pumps and the reason why one or several fuel injectors go bad. Malfunctions can also be triggered by simple parts, such as a breach of the Fuel Gasket lining the pumps, or leaks and pressure drops from worn or ruptured fuel lines. Caught on time, these issues will help you avoid bigger repair bills down the road.
