I was working on my 85 Shelby Charger and tried to start it. I turned the key and got a couple of clicks on a sillinoid under the hood. Also I have power to my accessories and a low oil light. I then swapped a computer out of my parts car and tried again. This time I had a check engine light with the rest of the clicks under hood. The cooling fan kicked on for just a second??? I wrote down the codes 11,12,55. The car has not ran since 1992. When the key is turned, the ignition and fuel system do not come on. I would be happy if I could just get the motor to turn over. Thanks.
