Howdy! "Long time listener, first time caller" here. A couple years ago I was lucky enough to get one of my dream cars, a 300zx, and all was well until it wasn't. A long story made not so long..
A friend of mine received a 1992 300zx NA 2+2 from his dad. He already had a good running car and doesn't know how to use a manual transmission, so he sold it to me. When I got the car it ran good, not great, but well enough to travel about 1500 miles back to my house. I've done a bunch of minor stuff like spark plugs, ignition coils, air filter, fuel filter and so on. The issue I am attempting to tackle now seems to be centered around the speedometer. Last year the cruise control stopped working and the speedometer became intermittent, at the time I didn't notice any issues with the power steering. Eventually the speedometer stopped displaying anything completely, but power steering continued to work until about 6 weeks ago.
I want to go back to using to using the car as a semi-daily driver, but its difficult without power steering (health issues). I've been trying to understand this wiring diagram I had found, unfortunately I don't recall exactly where I found it, maybe here? Anyways, before I go way off-topic, is anyone aware of which pin actuates the power steering solenoid or is it completely isolated from the ECU? I don't really trust the "Online AI Search Tools" which are telling me that it is Pin 4 on the ECU connector since that should be part of the Idle Air Control system.

The new engine is back in and the single turbo conversion almost finished but know the car won't start. Symptons
There is no spark, I thought I had fuel but now not so sure as I have plugged in a spare CAS and turned it and the injectors aren't clicking.
I am going to check the loom, PTU/CAS connections cleaned. I also changed the car loom with the fuse box, my guess would be something to do with that.
So my questions are, which part of the car loom could affect the electrical running of the engine? Any other suggestions?
Really want to get this conversion running so all help appreciated.
