Review Of 2008 Chevy Cobalt Check Engine Light Flashing Ideas. Web hey guys i have a 2008 cobalt and it just stopped working on me. If the check engine light turns back on, use fixd to get detailed engine diagnostics, plain english code descriptions, issue severity warnings, and so much more.

It doesn't crank at all. When the check engine light is flashing in cobalt, it indicates that there is a significant problem with the engine that requires immediate attention. Now, i need to get it smogged.
