Chosen Solution

I just got a new ignition switch but when I turn the key it wont turn the engine on. The starer is going but it just doesnt switch over to start the car. is there a step that I missed?

Don’t forget about this guide! There are 5 (five) wires going to the ignition switch. As it should be, I found that guide right here on ifixit dot com. I hope this solves your problem. Frank

Re-check your wiring. There should be three wires going to your ignition switch. One is ground, one runs the starter, and one is for power on in the run position. If your starter is running, but the car turns off when you release the key, it sounds like your power on wire is not connected or otherwise not functioning correctly.
