I got a 1990 yj with a 2.5 i had replaced the alternator and noticed that the bracket on the rear of the alt did not line up so i left the rear bolt out and threw it together. not paying attention and hooking up the battery the power wire to the back of the alt was touching the bracket (wore threw the rubber insulator) and hooked up the battery and very quickly disconnected it due to smoke haha. i fixed the alt issue and removed the bracket. the fuse able link to starter relay from the alt was burn so i replaced it and now i do not have spark or fuel. i have traced down wires to see if anything eles was burned i noticed i am not getting RPM readings on tach. I hooked a scanner to it and it has no injector pulse either. I am going crazy I took the computer out from behind the glove box and took the top off of it to see if i could see if there were any burns or bubbles nothing. Any help would be greatly appreciated. Thank you
