Fuel system symptoms
- Long cranking before the engine starts
- Hesitation or stumbling when you accelerate
- Stalling
- A fuel smell
- Fuel economy that has dropped

How we test
We measure fuel pressure and volume, review fuel trim data, check injector operation and smoke test the evaporative system for leaks. Many fuel-related lights turn out to be a small vapor leak.
