Good evening,
I have an 07 Maxima that cranks/no start. I plugged in a generic code scanner and received no communication. The radiator fans would run on high with the ignition on the run position. Purchased a programmed ECM online that is programmed to the VIN. I am still having the same issue. Any ideas of what to check.

Did you pair the key to the new ECU?

 

have not done anything besides install the ECM. Is there a process for programming the key? I just assumed it was already completed when it was sent to us as functions on the remote work with the exception of the unlock.

 

What is the security light doing?

Search for NATS (nissan anti theft system) or immobilizer programming. The new ECU has to be paired with your specific key(s). You can do it with the correct software, OBD (or Consult?) cable, and a computer. Or get a locksmith or dealer to do it.

 

 

Update. Had vehicle towed to dealership. They found that the place that done the kids oil change installed the air filter box improperly and it rubbed the wiring of the Mass Air Glow sensor. Causing the no start issue.

 

Ah, crappy waste of money. Glad you sorted it out, Kyle.
