HI All ! I got an 87 4.0 auto, it will not start. It previously screwed up on me about a month ago, it wouldnt start anymore with the key, i would have to go under and jump it off the relay. Now it wont do anything even tryin to jump it/ neutral /park. The battery has 13v, i can hear the fuel pump purge. I I beat the starter. I dont have any voltage reading on the dash with key "on" ? It did say 8v with key "on" during the month i was jumpin the relay but would go to 13 once truck was started. Now nothing!!! What im wondering about this is if this is a whole big short in my ignition since im reading no voltage on the dash, but the pump purges, radio was good till screwing with it. Now it just constantly clicks under the hood in the ""ON" position. What shall i do???
