The ignition switch harness has 5 pins: 12V(+), Accessories, Ignition, and two (2), repeat, 2 starter pins.

1 starter pin goes to the starter while another goes to the ECU. I think you're missing the other wire to the ECU. That's why it's cranking but not starting.


That wiring diagram is not correct for Nissan. If you're nice to me I can do a correct schematic for you. But first, you have to answer my questions:

1) What is the brand of the start switch?
2) How many pins does it have?
3) What does each pin do?
4) What is the maximum current (measured in Amps) can each pin handle?
5) What happens when the start button is pressed? Which pins are connected?

If you don't know the answer, contact the vendor and maybe they can contact the manufacturer.

If you can't get the answer, sell the switch and get another one from a reputable manufacturer. This is very basic information to wire up electronics and any manufacturer not willing to supply you with this info is shady.
