That is the is the check engine light, it means a failure in the emission system has occurred, take it to a Kragen or other parts store like it and they will run a test ( it is free) that will pull a code from the computer, that code will indicate the area or circuit that has a problem.

2004 cadillac cts wont crank at all, i turn the key and try to start it but it doesn't crank or do anything just the dashboard light come on and the engine light flickers then it wont release the key


I had something similar happen on my 2004 CTS. The car would not crank, and I recall the security light was on the dash. The key could be turned off, but not quite far enough to be removed.
The key can be removed by sticking a small pin or screw driver in a hole under the steering column... maybe 2 inches from the actual steering wheel. I recall there is a small cover or plug in the hole that needs to be removed.
You can let it sit and occasionally try to start it. My did start once more.
I ended up having it towed to the GM dealer and they replaced the ECM for about $500? That took care of it for a couple years, until I recently sold it.
