This guide is a little more comprehensive re fault codes: http://www.twinturbo.net/nissan/300zx/forums/technical/view/1105629/The-Ultimate-Guide-to-ECU-Diagnostics.html

Have you asked Jim@PZ if he has any s/h 370cc ones? I would imagine that he might what with upgrades to larger sizes for customers.

After a *long* lockdown hibernation (did just 255 miles in 12 months!) did a service and check over to make sure everything was OK. One thing that had decided to go awol was the oil pressure sensor which was reading low (at all RPMs) - a common fault. So it was replaced with new and the oil pressure gauge is now reading as it should. On RHD cars the sensor is located on the n/s of the engine block near the oil pan. https://conceptzperformance.com/wiki/index.php/Oil_Pressure_Sending_Unit

Time for the biennial insurance photos.

Nigel, welcome. You might have more success on the ZClub site https://zclub.net/ They have more Z31 activity.

Thanks for supporting the Club Adam and congratulations on your new Z32 adventure! Looking forward to seeing some pictures. Reading your post on seatbelts, is the car a UK spec?

Thanks for organising this Alex. I've registered on to the club stand.

Do you mean the red button?

Might still be in Nissan's UK/Euro stores: https://www.allcarpartsfast.co.uk/nissan/nissan-2613437p10-lens-front-turn/

Coming along nicely. What's the gadget on top of the right control pod?

Welcome to the Club JW and the start of your Z32 adventure! Pictures of your new collection addition would be great.

That interior is quite a transformation! Your car will be in very good hands at PZ.

It should be possible. Make sure the "studs" of the plastic clips don't get pinched between the new brackets and the bumper.

It's a small plastic expanding clip that holds the bracket in place whilst offering up the bumper to the studs.

Always a good idea!

If you are referring to the code 12, then this is the FSM diagnostics procedure: EFEC 112.pdf

23710-40P13 is for a 1990/08 - 1992/08 NA Auto car. Which assuming yours is an Auto is the right one. https://jp-carparts.com/nissan/partlist.php?maker=nissan&type=132&fig=226A&part=2371040P13&page=1 The Aux fan running on startup is normally an indication of an engine coolant temperature sensor fault (not withstanding a harness fault). It would normally generate a code 13 which your ECU is not showing. However, I've also come across an accounts on TT.net which also gives the same symptoms as you have described which was down to an ECU EPROM fault. I was asking about the EPROM inside the ECU (the four screws on the lid's corners to get inside) to see if the ECU has been modified or damaged in Japan. Unlikely, but you never know. http://www.twinturbo.net/nissan/300zx/forums/main/view/995323/running-rich-aux-fan-on-check-engine-light-on.html The engine is running very rich. New plugs will run for a while before they foul up and stop firing. Unplugging the coil packs will do the same on those fouled plugs. For reference, this is a link to ECU diagnostics using the LED on the side of the ECU. http://www.twinturbo.net/nissan/300zx/forums/main/view/1105629/The-Ultimate-Guide-to-ECU-Diagnostics.html

Just to check off things - Do you know if the ECU is stock (soldered or socketed/removable EPROM)? What is the Nissan part# printed on the ECU top lid? Will be of the form of XXXXX-XXPXX (eg 23710-46P80). What is the diagnostics software you are using the talk to the ECU?

Best wishes on your Birthday Craig!

Pretty self explanatory though!

UK spec (Manual) warning lights:

Z1 in the US publish a list of parts and a guide which covers most things: https://www.z1motorsports.com/z1-products/z1-motorsports/z1-300zx-automatic-to-manual-speed-conversion-kit-p-7341.html and https://cdn.z1motorsports.com/upload/Z1 Auto to 5sp conversion Tech.pdf plus the Auto ECU advance override modification: http://www.twinturbo.net/nissan/300zx/forums/main/view/1137609/Auto-ECU-in-a-manual-car.html This thread has lots of pictures for a conversion: http://www.300zxclub.com/showthread.php?t=85616 and for wiring (pictures missing): http://www.twinturbo.net/nissan/300zx/forums/technical/view/1001493/Auto-conversion-to-5-speed-wiring-info.html

New to me too. Just be aware that the Benley Motor Museum (and Bentley Wildfowl) is permanently closed if your are thinking of visiting them whilst at the show.
