Fuel System
Fuel Trim
The powertrain control module (PCM) is responsible for adjusting the fuel trim of the engine. It gathers data from multiple sensors to ensure the correct air/fuel ratio for optimal engine performance. The PCM constantly adjusts fuel trim to adapt to changing conditions like engine load, speed, temperature, and altitude.
Fuel Pump
The fuel pump is crucial to delivering the necessary fuel from the gas tank to the engine under high pressure. Without a properly functioning fuel pump, your engine may not receive the fuel it needs, resulting in poor performance or failure to start. Diagnosing and repairing fuel pump issues is key to maintaining a healthy fuel system.

Injector
Fuel injectors precisely deliver fuel into the engine’s combustion chamber. They adjust fuel flow based on input from the engine sensors, which helps maintain the correct air/fuel ratio. Dirty or malfunctioning fuel injectors can cause misfires, rough idling, and poor fuel economy.
Fuel Filter
The fuel filter prevents contaminants and debris from entering the fuel injectors and other engine components. A clogged or dirty fuel filter can cause fuel flow restrictions, reducing engine performance and increasing the risk of damage to the fuel injection system. Replacing the fuel filter at regular intervals ensures optimal fuel flow and engine performance.
Is your vehicle struggling to start or cranking longer than usual? This could be caused by a failing fuel pump or a blocked fuel filter.
Does your vehicle idle roughly or stall when idling? Dirty or clogged fuel injectors are often the culprit.
Does your vehicle lose power when going uphill or carrying a heavy load? This could be a sign of a fuel pump or fuel injector issue.
Are you hearing whining or buzzing noises from the fuel pump? These noises may indicate that the fuel pump is failing and should be inspected immediately.
Does your engine misfire or hesitate when you accelerate? This could indicate clogged fuel injectors or a failing fuel pump.
Have you noticed a sudden drop in fuel efficiency? This may signal an issue with the fuel injectors, fuel filter, or the fuel pump.
