2010 JKU will not shut off when the key is removed from the ignition

[2010 jk jeepwrangler]

We have replaced the starter. The Ignition switch and the tipm module and the engines still will not shut off with the key. You turn the key off and remove and all the gages go off, but the engine is still running, and the key is not in the Ignition. What are their ideas? Can you guys throw at us that we can check. The only way you can turn it off is to remove the fuse for the fuel pump

Since you've already replaced the starter, ignition switch, and TIPM, here are a few more things you might want to check:

Wiring and Ground Connections: Inspect the wiring harness and ground connections associated with the ignition system and TIPM. A bad ground could cause unexpected behavior.

ECM (Engine Control Module): There could be a fault within the ECM that is causing it not to recognize that the key is removed. If the ECM is stuck in a "run" state, that might explain why the engine continues to run.

Neutral Safety Switch: Check the neutral safety switch (if applicable) to ensure it's functioning properly. A faulty switch could send erroneous signals.

Relay Issues: There might be a relay issue in the TIPM that’s preventing the engine from shutting off. Sometimes, relays can get stuck in the closed position, which keeps the engine running.

Faulty Sensors: Investigate the crankshaft position sensor or other related sensors to see if they're sending incorrect signals to the ECU.

Last Resort - Wiring Diagrams: As a last resort, you might need to pull out the wiring diagrams for your model and trace the circuits linked to the ignition system to investigate any anomalies.

Try to work through these suggestions, and hopefully, one of them will lead you to a solution. Good luck!

With the key out and engine running, is the Jeep drive able? If it's an auto, does trans shifter still work? Does steering wheel lock? Etc.. Does it function as though the key is in and in the run position.

After you installed the new TIPM, did you have it "flashed"? Was it delivered to you "pre-flashed"? If the new unit was delivered undamaged, it could be a software problem.

 

[WSS]

Good point about the flash. The new tipm would relay the same issue if not flashed.

Is the steering wheel locked? Can you shift gears?
What are you doing about it now?- just letting it run until it’s out of gas?

To stop it he pulls the fuel pump fuse.

Thank you, Chris, for the ideas we did work through them last night. Unfortunately, none of those were the problem. We are leaning towards the key cylinder as being the problem, when my husband replace the ignition switch, when I would put the key in the
Key cylinder it seemed harder to turn both auxiliary and to start. It was a hard click click, so I'm thinking, maybe that could be the problem. , but we're having a problem finding a way to remove that. Maybe you can direct us to a good website for direction. Thank you again for your advice.

It could very well be the key cylinder. Let us know what you find after inspecting it.

No with the key out the engine's still running, you cannot shift it into gear or anything. You have to turn the key into the on position. To move it

 

[WSS]

That narrows things a little. The problem is not in the column.

So throw some ideas at us.. Any ideas would be great thank you
