if that's the case its power to the ecu that's the problem, the ecu turns the eccs relay on when it itself turns on. so the problem may lie in the ignition switch or wiring to the ignition switch,

Its a black red wire to the ECU pin 36 that turns the ecu on
theres a white wire at the ignition switch that should have 12v at all times, if not blown fuse or broken wire. then once the ignition switch is ON the black red wire should also have 12v of power that it feeds to the ecu to turn it on.

super easy to test check 12v at white wire ignition off or on doesn't matter
then check for 12 at the black red wire on the switch, ignition in run position
if all is well check for 12v at pin 36 on the ecu also a B/R wire.
youre problem is going to be somewhere around there

(wire may be slightly different color if you have a SOHC car 89-90)
