i have a lincoln towncar 1990, My fuel pump isnt turning on, this happended before the wires that went into the alternator melted, i had to replace the alternator plug, but this time it wasnt the problem, i followed the alternator wires to the battery and saw that some wires were bare and they might have touched some metal, what would that short out?? i checked the fuelpump relay and found out that is wasnt getting power, but some were, what exactlly do i need to replace it?
