Thanks for the step by step. Unfortunately probably the weekend before I can get back to it. CHT is new and I can try the other tests mentioned as well. Kostal connector for injectors is seated properly at firewall but as mentioned PO tore through lots of wiring when converting the car to track use so it is all suspect.
I'm very heartened by the engine catching with starting fluid. I feel we are really close. Someone mentioned that if one injector is shorted, none will fire. I disconnected 3-6 and tried to fire, nothing. I can try the same on the other side but likely unnecessary if I test each alone. It's a little tough to get test leads firmly on the mid and firewall cylinders.

You may want to get yourself a simple oscilloscope (less than 30$ on evil bay) to make it visible. A multimeter will not help here. If it's not present check the wiring.
Disconnect all injectors and ohm out the GRY/WHT and GRY/BRN wires on the injector connectors back to the ECU connector pin 14 and pin 15 respectively. That's all there is to it.
