My ignition key tumbler seems to not be making any connection. It feels empty when turning. I replaced it and the new one does the same thing. I can not get the vehicle to start. I did some checking around and I felt I had some of the symptoms of a Transmission Range Sensor that had gone bad. I replaced the TRS today and that did not solve the problem.
Symptoms
1. The key tumbler seems loose in the column and feels empty when turning.
2. When the battery is connected the radio, door locks, windows will operate. Even after replacing the TRS.
3. When this first happened I could shift from park with out placing my foot on the break with or without the battery connected. After replacing the TRS and taping on the steering column I could not shift with out placing my foot on the break but was not able to start the car. The tumbler still seemed empty. After some more trouble shooting I some how reversed my “progress” and now I can shift with out my foot on the break again.
Trouble shooting
1. Replaced ignition key tumbler
2. Charged battery.
3. Checked starter and starter solenoid both ok.
4. Replaced transmission Range Sensor.
5. Checked all fuses.
6. Took plastic covers off steering column and nothing looks broken or out of place. When turning the key there is a piece that runs along the column that doesn’t quite look right like maybe there is a spring that should push it back toward the driver.
7. Gave up for the day!

I have recently removed my air condition compressor and replaced it with a bypass pulley. I could hear a small vacuum leak when first starting the car. Other than that the car has been running great.

Not sure what is causing this any clues or advice would be greatly appreciated!

Hi Jayball98,

Thank you for the donation.

The ignition key would travel freely by itself and it is not the cause of the problem.

The ignition switch at back of the key cyliner is the one that has a spring loaded return and check ball for each detent the ignition key is turned to.

Check the ignition swich first, it could be the cause and solve many of the problems. We start from here.

As to the compressor replacement and noise, could it be due to the belts? dry or out of alignment belts can cause a fine wheezing noise when cold.
