after finally figuring out the Ignition Control Module was bad in my 91 teg I swapped one off my 90. Once I had it put together it cranked almost instantly after turning the key. Then I go back a minute later sparks once then quits. I don't know if something killed it or it just died due to the donor car have 257K on it is there anything that could have fried it?? If so what do i check

 

Also does anyone know how much a new one runs
