87 2.8 injector problem
I have an 87 2.8L with an electrical problem. I’m assuming either bad injectors or bad ecm possibly. Injectors are not firing, I cheated a little and hardwired the fuel pump to the battery with my own inline fuse and switch to get it to turn on, is there any way I can cheat a little more with the injectors and be safe? I do intend to do a full engine harness replacement soon but I need it running for the next week. Previous owners chopped up the wiring on the firewall.
This is what I meant when I said it’s chopped up

Re: 87 2.8 injector problem
Im assuming the ECM has power because the idle air butterfly or whatever is next to the main butterfly, is opening on key turn but im not sure. the tags expired in 2013. i am more on the mechanical side and dont have much electrical experience, could you explain where / how to check with a noid light?

PS, just curious, have you checked this fuse yet? (you'll get no injector pulse or fuel pump action if it's blown or missing)
