i have a 93 toyota 100 with a 3 ltr engine that has no spark, no injector pulse, and keeps setting a code 12. i have tried coils, ecm's, igniters, distributors all to no avail. i have checked wiring for proper power and grounds all ok.also tried new relays to no avail. now running low on patience with the damn thing, any help would be appreciated. thank you, Bob @ martins auto.

tried efi main relay, and circuit opening relay. neither one helped
A code 12 is no ignition signal to the ecm while starting. did you try unplugging air flow sensor and trying to start?
Inertia switch tripped?
