Colt harness runs to a fuse box at the front of RH fender/strut tower. That is where fuses and relays for the engine bay components (other than AC) are located. AC stuff is located in front of the power steering fluid reservoir and is likely the same between turbo and non-turbo for fuses and relays.
Check for fuel pump operation with the check wire on the firewall - it will be detailed if it is GND or PWR you apply to it to turn on the pump.
Removing the CAS and rotating it will confirm the injectors are firing, and the wiring to the CAS isn't broken and has good connection but then you have to set timing again.
Inspect the ECU for signs of damage:
Google DSM ECU damage photos What to look for and have a sniff of the ECU also. If it smells like bad seafood, something could be leaking.
Also check for green terminals or broken wires at the PTU, the power transistor down at the drivers side of the head/intake manifold. 6 pin connector and black plastic module with a three screw plate holding it in place.
that's the unit down where the intake and head meet.
