06 altima no spark, no start

[Presscott707]

hello everyone I was driving the car the other day and it just shut off and would not start back up. I just changed all coil packs about one month ago. I pulled all the coil packs and none of them are giving spark. I read the check engine light and it had a P0420 for catalyst performance, P0725 Engine Speed sensor, P0335 Crank Sensor, and P2A00 for bank 1 sensor 1. I replaced the crank sensor and still nothing. then i check the fuses and they all check good. what is next, what am i missing.

Could it be that the key lost its programming maybe? Im going to try it in the morning. Please help me

Did you figure this out?

I’m thinking when you changed the crank sensor you probably should have changed the cam sensor as well. If you have a cheap scanner clear the codes after you replace them. I’m gonna also suggest using the other key if you have one. Maybe Prescott is onto something. Seen that happen before.
