The main components to check are the battery, coil, the distributor, its cap and rotor and the associated wires from the coil to the distributor and from the distributor to the spark plugs. Distributor is on the front right side.
When you get an Ignition Spark Circuit code on a 1990 Nissan 300ZX, first check the ignition system components, including the ignition coil, spark plugs, and wiring for any visible damage or corrosion. Next, use a multimeter to test the resistance of the ignition coil and verify that it falls within the manufacturer's specifications. If these components are functioning correctly, inspect the wiring harness and connections for shorts or breaks. If necessary, consult the service manual for further diagnostic procedures specific to the ignition system.
To remove the key from the ignition of a 1990 Nissan 300ZX, ensure the vehicle is in the "Park" position. Turn the key to the "Off" position and press it in slightly while attempting to turn it to the "Lock" position. If the key doesn't release, check if the steering wheel is locked, as this can sometimes prevent key removal. If the issue persists, there may be a problem with the ignition cylinder that may require professional assistance.
I'll try to be brief, because this is a long drawn out procedure, and if you don't know how to do these, or can not get anyone to help you let me know. First check fuse. Second check ignition wire from switch to starter. Third check starter relay, and last if all doesn't check out okay, check the wiring between these components.
The 1986 Nissan 300ZX typically has one fuse that connects to the radio, located in the fuse box. This fuse is responsible for supplying power to the radio and other audio components. It's important to check the owner's manual for the exact fuse location and specifications to ensure proper replacement if needed.

To replace the heater core in a 1984-1989 Nissan 300ZX, first disconnect the battery and drain the coolant. Remove the dashboard and the center console to access the heater core. Detach the heater hoses from the core, unbolt it from the housing, and then install the new heater core by reversing the disassembly steps. Reconnect all components, refill the coolant, and check for leaks.
To tune up a 1986 Nissan 300ZX, start by replacing the spark plugs and ignition wires to ensure optimal combustion. Check and replace the air filter and fuel filter for better airflow and fuel delivery. Inspect and adjust the timing, and ensure the battery and alternator are functioning properly. Finally, change the engine oil and filter to keep the engine well-lubricated and maintain overall performance.
To read diagnostic codes on a 1990 Nissan 300ZX, first, locate the diagnostic connector under the driver's side dashboard. Use a jumper wire to connect terminals E1 and TE1 in the connector. Then, turn the ignition key to the "on" position without starting the engine; the check engine light will blink the diagnostic codes. Count the blinks to interpret the codes according to the Nissan service manual for troubleshooting.
For a 1990 Nissan 300ZX, it's recommended to use a high-quality ethylene glycol-based antifreeze that meets the specifications for Japanese vehicles. Look for a coolant that is phosphate-free and designed for aluminum engines, as the 300ZX has aluminum components. A 50/50 mix of antifreeze and distilled water is ideal for optimal performance and protection against corrosion. Always check the owner's manual for any specific recommendations regarding coolant type and maintenance.
