Where is inertia switch on a 2011 Nissan titan?
I don't believe there is a fuel shut off switch in a Titan Not sure what the situation is but if you have changed a computer you need your keys to be reprogrammed, if they are not the security system shuts down the fuel injectors. Perhaps this is related to your problem.
I don't believe the titan has fuel shutoff inertia switch. I only know of Ford vehicles having them.
