- Fuel odor, wet connections, or damaged delivery components.
Testing before parts
Fuel and ignition symptoms can overlap. A fault code or a rough idle should guide diagnosis rather than identify a pump or injector automatically. Cleaning can be appropriate for certain deposits, but it cannot repair electrical failure, physical damage, or a leak.
Take fuel leakage seriously
If raw fuel is visible or its odor is strong, park safely, shut the engine off, and avoid ignition sources while arranging professional assistance. These pages explain individual services; the correct scope depends on the vehicle and the findings.
