02 I 35 starting issues

[BIvey]

I have a 2002 I 35 with just over 10400 miles. I recently replaced the alternator and battery. Everything ran fine post replacement. The other morning I tried to start it, nothing. It turns over fine, just won't start. I replaced the spark plugs and the cam sensors and still won't start. Any ideas. Thanks.

Have you checked to see if you're getting fuel and good spark? That'd be my next step.

I actually wasn't getting spark but apparently it wasn't an underlying problem. Turned out it had to do with the security system and the chip in my key. I used the spare key to unlock the car manually, once inside I had to lock the doors and it started right up. I locked the car manually on the way out, now it seems to work just fine. I appreciate the feedback.
