Hello, I have a 2014 Cadillac ATS with the 2.5-liter non-turbo engine & about 2k miles on the odometer. The car has been in the garage and untouched for at least 4 years, body & interior look perfect, and in-car electronics work when I charge the Battery, but it won't start. What should I do? -Thank You

The fuel system is probably a mess. Modern ethanol-contaminated fuel starts deteriorating within months, especially if fuel stabilizer was not added. Even with the stabilizer that's only good for a year or two at the most. Assuming the engine cranks, you can easily test whether it's a fuel problem by spraying some starting fluid into the intake and cranking to see if it fires up.

For further troubleshooting information see the FAQ.

  • Probably bad gasoline 
  • Does it crank?
