New harness, new ECU, NO spark NO fuel....
So I sold my FD at the end of last year
After no payments for almost 7 months, I took it back.
It was in almost the same shape as when I sold it, except the wheels were haphazardly sprayed black, and the rotors and disc brakes too......
It was in the midst of a single turbo conversion, so I completed it.
Rytech single turbo 5spd harness, 1450cc secondary injectors, FPR, Fuel Pump, Adaptronic ECU...
I had it started, roughly on the stock harness, and PowerFC before selling it - just to check for leaks.
Now I have no TPS signal (the old owner ripped the TPS plug off the harness, I am guessing my TPS is toast.....)
The motor is still cranking strong, still good compression, but it wont fire.
I have had my settings and tune looked over, and was told it should start the car..
42-45 PSI @ the FPR / Rail
No gas smell when I turn the key.
I am wondering if the AT to MT swap would have anything to do with the car not firing, when it worked fine before.
Attached are pics of the plugs just left hanging due to having no mate by the ECU.
Help a brutha out; not too much support for the FD in my local area any more - JCR moved back to the promised land

Your wording is very confusing but I’ll try to understand what you are saying.
The car will not start without a tps so you need to first fix that issue.
no spark/fuel is generally no power to the ecu. That means you have a power issue to the efi and main relay. Using a tester light, check the fuses near the battery for power.
If those do not have power, start tracing where those fuses should be getting power from which is the main relays located right near driver side strut tower.

Spark and fuel are good. Plugs were completely fouled. ECU has power. Guess I am searching for a TPS.......
The plugs depicted, I am guessing they go to the dashboard??? and the Rywire bit is going to the Mazda bit??

I still have my old harness, so I can make some pinn'd connections - I just need a manual chassis plug for the end that goes to the Rywire output. If I am looking at this correctly.
Just connect a labtop to the ECU, and check all the details sensors. Do you see rpm when cranking ? You will need to download the Eugene software from adaptronic.com.au ( downloads section).
