Hyundai Sonata 06 engine runs key out ignition in off position
Hyundai Sonata 2006, 4 cylinders. On two occasions the engine has failed to stop after turning the key to the off position and removing from the ignition switch. While the engine was running none of the gauges operated and the transmission was licked. Engine stopped after I put the key back into the ignition switch 2-3 seconds later.

Many times a cylinder will not turn when the steering wheel lock has pressure against it from the steering wheel. Wiggle the steering wheel while trying to turn the cylinder. If this is not the issue, the cover surrounding the steering column will have to be removed to access the cylinder.
Proceed like this :
(1) Check the fuel flow , could be problem of fuel pump.
(2) Check the camshaft and crank shaft position sensor , there must MIL light glowing because of it. If yes , The Camshaft Position sensor is typically located in the cylinder head of the engine and has a cylindrical portion that inserts into the head. The Crankshaft Position sensor is normally located in the timing cover or on the side of the block with a cylindrical portion that inserts into the block.
If No, fuel pump could be the only problem.
Do you hear a click when operating the key ? if not I would suggest perhaps it is the starter solenoid not making contact and powering up the starter, the quick check is to employ the help of a friend, locate the starter ( make sure the car is out of gear or in park ) get your helper to hold the key in the start position and you tap the starter with a hammer or the like, if the engine bursts into life it's the starter, if not the chances are it's the switch, Be careful when doing this and be sure to keep clear of the fan an pulleys.
If you are not an experinced locksmith you cannot do it without damaging something. Call a locksmith. Those guys know how to release the lock in different cars. You have to remove the steering wheel before hand though to reduce the time he/she will spend on your car.
The 2003 Sonata is equipped with a 'starter KILL' burglar alarm system with disables the starting system (using a N/C 'contacts' configuration instead of a N/O contacts configuration). N/C=Normally closed, and N/O=Normally open contacts. When the alarm goes off with a MY Sonata, the only way to DISARM it is with the key fob (remote) originally programmed for it (unless you purchase a new remote & have it programmed for the vehicle at an authorized Hyundai Service Department). NOTE: So long as the keyless entry & burglar alarm system is functioning/operating normally, the alarm will keep going off and the STARTER KILL function will still prevent you from starting the vehicle. One option is left without purchasing a new remote and having it programmed. 1. When the alarm goes off, get into the vehicle and insert the ignition key into the ignition. 2. Turn the key to the 'RUN' position (NOT the ACC position) and wait for the alarm to STOP (usually about 3 to 5 minutes). 3. The engine should then start using the ignition key.
If this procedure doesn't work, the problem will need further diagnosis by a qualified/certified Hyundai Service Technician.
You are either not getting spark, or fuel or no compression in the cylinders, or your engine is flooded with fuel and cannot run because there is too much fuel and not enough oxygen to burn the fuel.
There are so many things that can cause these things that we cannot even begin to list them here, First you have to isolate the SYSTEM that is failing. (spark, fuel, or compression.) Then you must diagnose that system to locate the cause of the failure.
My online Sonata manual shows these possibilities, but does not identify which applies specifically to 2000 Sonata. Also, when you talk to the dealership parts counter, you'll need to know whether your 2000 Sonata is (a) 4-cylinder 2.4L MFI DOHC engine, or (b) 6-cylinder 2.5L MFI DOHC engine. Its easy to tell - just count your spark plug wires.
