2003 Nissan Sentra, automatic, 190k miles
I have this sentra, high miles but drives great.
Was suppose to sell it to a friend, to help pay rent and take care of things.
But now I can't, because after changing the steering wheel. Car will not start.
It will crank, but not start. I did take some relays out of relay box, and put it back in. I was looking for the horn relay, because it was stuck on. That's only other thing I did.
Car was running totally fine without an issue beforehand.
Switched old steering wheel back, and still won't start.
Checked all fuses they are fine.
No engine lights
You probably disturbed some wiring. Maybe damaged the clockspring, though I woudn't think that would prevent the car from starting.
Carefully go over everything you touched and see the troubleshooting section of the FAQ. You can find a shop manual for that here which may help:
