So far I've checked the coils, wires, plugs, compression, and injector clip with a noid light. Can't find any issues. So I replaced the fuel Injector. Still doesn't fire on #5. I was looking for info to check the wiring to/from that specific injector, but the tsrm didn't detail that in the fuel system troubleshooting section. This is a batch fire setup, so I don't understand why another Cyl. Wouldn't be missing.
