Question about 1989 Nissan 300ZX

1 Answer

I need to find the ecu relay for an 86 Nissan 300zx.

The car will start and run for about 2 seconds and then it shuts off. It acts almost like its running out of gas. Car has fuel in tank, new pump and new fuel pressure regulator. The battery was hooked up backwards so I think it fried the ecu or hopefully just the relay.

The ecu is probably under the passenger seat. The battery also has a fusible link which may be blown. Also follow the battery wiring to the regulator box. This may also be faulty

My 1984 nissan 300zx starts right up but after about 30 seconds shuts off


Sounds like something is loading up extra power to the ECU, or corrupting the operating instructions loaded into the ECU.

The die out sounds like when the car gets out of "cold start loop" and hands the job over to another another part of the computer system.

I think I might go to Autozone.com and get a free wiring and fusebox diagram. This is free after you register your car on their site.

Look for Ignition Relays or the ECU relay and replace the relay. Could be generating a short and erase operating instructions.

You could also try to find out if the ECU is programmable or is READ only. The info may only need to be reentered into the ECU if it was corrupted.

Check the connections to the ECU, as installing the new ECU was not as important as renewing the connection on the dirty plugin socket.

I hope my solution is helpful, please rate the info.

My 86 300zx starts then shuts off


Hi,
check the fuel rail for correct fuel pressure. If the Pressure regulator is faulty, the fuel pump will send fuel to the fuel rail, but it will be dumped back to the tank if the pressure regulator is bad, The fuel needs to be pressurised to go through the injectors and into the cylinders.

Good luck.

This is more complex and you won't find anyone to give you advice. Dealer solution on this one.
Sometime they don't even know and guessing.

Maybe it's time to buy another car?
