I have to hold and press cruise control to start my car

Hi,

This is a tough one just because the two are unrelated when it comes to starting. If I had your car at my shop, I would start by taking the plastic trim off the steering column and checking to see if something is loose in the wiring. I say this because the multi function switch and the ignition switch are near each other. Moving the switch a specific way may be moving something.

Here is what to try. I am going to supply the directions for replacement of the ignition switch. I am not saying to replace it, but rather the directions will show you what needs removed on the column to access wiring. Remove these things and once you locate the switch wiring, turn the key to start and try moving the wiring around to see if you can get it to start. There may be something loose.

Here are the directions. Let me know what happens when you try this. Also, the attached pics correlate with the directions.
