I just went through a similar exercise after replacing and injector on my '99. The injector #3 wire was caught against the throttle cable support bracket. Engine was running great and then instantly stopped when I moved it. Kept cranking and would not start. I sprayed some starter spray into the throttle body and nothing. I checked all the injector and sensor connectors and tried cranking a few more times, still nothing. I had taken the fuel rail off to replace the injector so I pressed the valve and fuel sprayed out. Checked that a few times and definitely looked like I had fuel pressure. Next was spark. Removed a spark plug and then put the wire and plug by the block while I had someone crank the engine. No spark. I checked the CPS and saw infinite resistance between terminal b and c. After all that cranking, the check engine light finally came on. I forget the code, but the description was auto shut down circuit had no voltage. I did some googling and checked the ASD relay by swapping. Still no go. Did some more searching and found there is a 20 amp fuse in the engine fuse box. That fuse is triggered by ignition components including the injectors. I was looking for which fuse # it was and of course can't find it right now. It's a 20 amp fuse and was blown. I replaced that and it fired right up. My guess is when I moved the injector, it shorted against the bracket and blew the fuse.
Point of the story. check fuel and spark. It has to be one or the other missing.
