I have a 1989 mustang lx 5.0, the other day i was driving and it shut off, i looked under the hood and notice a melted wire on my headers it was the after market coil wire, so i hooked the stock coil back up. but i have no spark,and the fuel pump isnt kicking on, I went under the driver side set and played with the fuel pump relay and if i run two wires to jump the holes the pump kicks on. but still no spark, what do i do ? what fuses or relays need changed ? how much is a relay ? or anything else i may have to buy please help me find out whats wrong. i dont know what else it could be if you have an idea please tell me how to fix it or where it is at on my mustang so i can check it out, thank you
