When I backup I can see the camera but it won't beep when I'm to close to object.

Hi everyone, this is my situation: due to temperature problems, the cylinder head gasket was changed. Once assembled back, it wouldn't start. The starting motor turns but he engine won't start, what means, it has no injection. The camshaft sensor has been checked and it sends the right pulsations, just as the crankshaft sensor, but the computer won't give pulse to the injectors. That is the one and huge problem. What might have happened? May have some anti-crash switch been activated? I hope someone can help me. Thanks! It would be really helpful if anyone had the injection system's diagram of the Nissan Frontier/Navara/pickup, depending on your country.

I own a Frontier diesel 2006 and the failure it has is that it takes long to start working. I have to try for at least four times and, once it starts, I want to speed up but it won't accelerate. It chokes and only reaches 1100 rpm, not more. I've already changed the crankshaft's sensor, potentiometer, fuel relevator, fuel filters and the temperature sensor but it is still the same. What else might it be?

I replaced the knock sensor concerns. I'm blowing 40 amp ignition fuses under the hood. I replaced the knock sensor but everything back together the way it's supposed to go the way it was all the plugs are plugged into their respective partner since they won't plug into any other plug so they have to go where they go the only concern I have is on the back of the alternator there is smaller threaded holes there is a wire hooked up to the back of the alternator acting like a ground it's a black wire that comes out of the harness and another wire that comes out of that harness goes down to the oi… Read complete

I had changed the sensor behind the supercharger and before and after it still the same. Idle not good. Up / down erratic. Supercharger has a noise

Tengo una Nissan Frontier automática, cuando voy en desplaze se apaga de momento, el acelerador no responde, olor a gasolina y se escucha una detonación, tiene los inyectores nuevos, sensor de flujo de aire nuevo, sensor knock nuevo. Alguien me puede decir a qué se debe. La he llevado a varios mecánicos pero el problema persiste.
