I've considered that ;-) However this way I may miss other reasons CEL is on

I don't know what is the injector inductance. Alldata only specifies
resistance of 12 ohms

Yep, 8 relays it is. I've considered it, but this would mean ungainly bundle
of wires, relays and coils of unknown inductance (or injectors from
junkyard). Are there relays that will switch 4/8 separate circuits?
