My car isn't starting & have discovered that there's no power(noid light test) going to the injector harness, I'm wondering if there's an EFI(Electronic Fuel injector) relay? Thanks.

The main plug near the power steering reservoir has the main power feeds to the ECU and engine components. The white wire with a black stripe provides power to the injectors direct and also provides power to the ECCS relay and direct to ECU pin 58 (battery power supply). With the engine not running you should have battery voltage at this wire. If you don't you need to check the fusable links under the cover of the engine bay fuse holder. It will be a 25A fuse (should be one of the square units with clear cover and probably brown in colour). I think it is the one closest to the spade fuses.

Hope this helps.

Cheers,

Thanks bro! Yep that fusable link in the engine bay fuse holder was the prob. Cars starting now! But my speedo doesn't work now...lol. Anyhelp would be appreciated...

You will have to remove the instrument cluster and check that the cable is still turning with road speed and that the speedo drive adapter is still located on the end off the cable (a small square plastic pin).

R32's were the last to have a cable driven speedo, archaic design and know to be an issue.

A new cable from nissan is ~$100 so not unrealistic.

      Mistakes were made, my R34 Story

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
