Ok, My Brother Savers

I am looking in the SKREEM section trying to find out how fix my fixes. the deeper i get the more i get myself in trouble ( I dont blame you guys) you have a great source of knowledge and help.
I am trying to understand my best way of fixing /attacking this problem SKREEM.. I have had the 2 starts and dead and pull the battery cable to clear the memory and retry starting - same results. Which lead me here with the deepest of Ah Sh$^ feeling. Once again I and looking for you to pull me out of this hole (wish i never changed the radio). What is done id done.
Help my savers-please
Thanks like always
