that 89 pdf diagram posted above, is for a motronic bosch spider, not L-jet.
you said "I checked injector connectors and they get energy only when the car starts"
they should get 12V to both pins, KOEO/key on engine off!
when cranking the ecu pulses them, by interrupting the ground.
I can send you a coloured diagram of an 88 spider, which will be mostly similar to your 86 spider.
send me a PM with your email.
