had problems starting sometimes, had to use a couple squirts of starting fluid and would normally start right up and afterwards had no prob running but sometimes had to wait for about fifteen minutes for it to start (did this wether it was hot or cold) and now it cranks over but wont get spark, checked ECU and it is not coming on, checked power off of relay harness and wire on bottom right (it's either the wht wire or ylw/blk) displays an OL, is it possible the relay is bad? or do i have to replace wire?
