The only items that could cause the starter to continue after the key is returned to the 'Run' position is either the starter solenoid hanging or a relay that may control it. If the starter solenoid is hanging, the contact surfaces are probably damaged which may explain the poor starting. In some cars, the solenoid is integrated into the starter (and replaced with it), others are a separate item.
If the car will start at all, go to a nearby auto parts store and have your computer scanned; it may contain info as to the defective part. If the car is non-op, call them to see if they rent scanners so you can obtain the error info yourself. It isn't difficult and the connector is not hard to find; in most cars the connector is located on the driver's side under the dash. It is a flattened 'D' shape and horizontal.

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.

Where is the idle control sensor for 2004 Cts Cadillac


There is none.Idle is controlled by your computer. If you have problems, check these. Vacuum lines behind throttle body. You may have to replace your air flow sensor. You can also try this:
Engine cold.
Turn your key to on position for a full minute. Don't start the car.
Turn key off for 10 seconds
Turn key on for 10 seconds. (Don't start)
Turn key off for 10 seconds. Then start the car. Might work but in all probability your main airflow sensor (MAP) is the problem.

My key is stuck in the ignition of my 2006 cadillac cts


2005 CTS 3.6 Dead battery, key stuck, service anti theft and nothing happens when you turn key, Ttried everything, ECM reset, key memory reset, charged battery to 12.7 volts, locked door w remote and opened w key, anyway you get the idea. After 3 days of online reading and trying, THIS IS WHAT WORKED, 1. put key into on position 2. removed sarter relay from front fuse panel 3. jumped 1st pin closest to fender and passenger seat with pin that is closest to motor and front fender. I used a paper clip and just made contact long enough for car to start. ran car for five minutes and took key out and everything went back to normal. then I took car to advance auto parts to have engine light reset. if car does not go back to normal you have ECM (car computer) failure. video on YouTube under "no crank, no start"

Okay, to program a key you will need two keys that are already programmed, insert one key ignition turned on and engine off, remove the key and within 10 sec insert the second key and turn ignition on with engine off, remove that key and within 10 sec insert the key to be programed. you will need to do a 30 min.relearn with only one key,you will turn ignition on with engine off and wait about 10 min until light goes out then remove the key and repeat this step when light goes out repeat step one more time then use key to start car, computer has learned all info. you will now turn off engine, insert programmed key turn key on engine off then remove the key and insert key to be programed within 10 sec.all done good day.

Sounds like an ignition switch problem. Thats one for your mechanic. To get your key out make sure you are in Park (This comes from experience). Good luck.
