What's involved

What this repair actually is.

We measure fuel pressure and volume, scan for fuel-trim and misfire codes, and test the pump, injectors, and regulator to find the true cause of a no-start, stumble, or power loss. Fuel problems mimic ignition and sensor problems, so proper testing saves you from replacing parts that were never broken.

Symptoms

How you can tell.

  • Engine cranks but won't start
  • Long cranking before the engine catches
  • Hesitation or loss of power when accelerating
  • Rough or uneven idle
  • Black smoke or a strong fuel smell from the exhaust
  • Check engine light with fuel-trim or misfire codes
