Yes, turning off the ignition switch typically deactivates the relay coil in automotive systems. This action interrupts the electrical circuit that powers the relay, causing it to disengage and stop supplying power to connected components. As a result, systems reliant on the relay, such as fuel pumps or ignition systems, will also turn off, preventing any electrical operation when the vehicle is not in use.

Power gets to a 300ZX coil through the ignition system, which includes the ignition switch, ignition relay, and wiring harness. When the ignition key is turned, power flows from the battery through the ignition switch to the ignition relay, which then sends voltage to the coil. The engine control unit (ECU) also plays a role by controlling the timing of the spark, allowing the coil to generate a high-voltage spark needed to ignite the fuel-air mixture in the engine's cylinders.

To wire a switch to a relay, first connect one terminal of the switch to the positive power source. Then, connect the other terminal of the switch to the relay's coil terminal. Next, connect the other coil terminal of the relay to the ground. This setup allows the switch to control the relay, activating it when the switch is closed.
Ignition what? Switch? Coil?
Yes, the ignition switch is responsible for powering the ignition system, which includes the ignition coil. When the ignition switch is turned on, it allows electrical current to flow to the ignition coil, enabling it to generate a high-voltage spark necessary for igniting the air-fuel mixture in the engine's cylinders. This process is crucial for starting and running the engine.
A fuel pump relay provides power to turn on fuel pump. A relay allows small current to control high current- example- a starter relay-- If you didnt have a starter relay- the big thick starter wires would have to run to the ignition switch, and then back to the starter. with a relay- you only have little tiny wires running to the ignition switch... when you turn the ignition switch on, a little bit of current goes through the tiny wires to the relay- which powers a coil- which then makes the contacts inside the relay connect- which then allows the high current to run through the big wires to the starter. kinda simple- but can be confusing. carmine C-

To determine if you need an ignition switch or an ignition coil, you can look for specific symptoms. If your vehicle doesn't start, but lights and accessories function normally, the ignition switch may be faulty. Conversely, if the engine cranks but doesn’t start, or if you experience misfires or stalling, the ignition coil could be the issue. Testing these components with a multimeter can provide further confirmation of their functionality.
Blown fuse or bad ignition switch or crank sensor?
This will be because someone has changed the wiring configuration - The electric window relay should be energised via a switched 12v (either straight from the ignition switch or from ignition relay) to switch a bigger current to power all the windows. In this case someone has removed the relay coil 12v feed from the switched source and connected it to a permanant source (straight from the battery and not via any switches.) -Daz Ellerington.
