My 04 z is in the shop because the NATS isnt allowing the car to start... the nissan dealership is having problems diagnosing the electrical problem. they tell me that all the mods that i have on the vehicle is what is making it not be able to turn over, just crank. "electrical issue" is what i was told. If it is the NATS... would it really matter what bolt on mods i have? if so... is there a way to bypass or disable NATS? could i remove NATS and install an aftermarket security system?

 

Short answer - no.
