If there is any issues with the fuel injectors this will cause the injector codes to set here.I would have the wiring checked leading from the ecm to the injectors for any issues and if any issues are found the issues will need to be corrected to resolve this fault here.If this is or has been checked and if the injectors were tested and found o.k. let me know so we can continue.

If you clear out these codes do they all come back up again at all?Have you checked for any engine wiring issues on the engine needing repaired or replaced?
O.k.,my info isnt listing some of these codes here myself but someone else here may have more info on this.

Hi there. Do you still need help?
Trying to diagnose this system whithout the proper tools is like trying to cut down a 100 foot tree with a kitchen knife. So, based on the information you posted, if I had to guess, I would say the ECU is bad. Other than that, you'd need a scan tool capable of communicating with the Trionic computer and getting sensor data from it, plus a scope to confirm the signal; then I could talk you through the diagnostic steps.
I'm afraid your multimeter won't help us unless it is something like a Fluke 199C, and even then we'd also need a capable scan tool.
Trust me, our goal is to help our customers so we can make a little money ourselves. I would not have mentioned the scan tool and the scope if those were not absolutely necessary. The reason why it is so, is because both the injectors and the air-charge solenoid are actuated by pulse-width signals from the Trionic computer.
Please don't shoot the messenger... I understand your plight and the risk you're taking by sinking two grand into something that might not fix the problem. There's nothing I would love more than for you to have the proper tools so I could help you and, in doing so, perhaps even getting a little money for myself.
As things stand, the only other recommendation I could make is to make sure there are no short circuits in any of the injectors or the waste gate solenoid or related wiring that might be there waiting to kill the new ECU.
By the way, it looks like you can do much better than $2K... click here to see
