When my 91 FJ80 gets hot, it doesnt want to start. I can hear a the starter clicking, but it wont turnover at all. It only happens when truck is hot, and was thought to be starter contacts, but after replacing them the problem was back within a week, so I bought a brand new starter, and its done it the whole time. It only happens every now and then, and if you click it over enough it will start, but I need to get it fixed before I sell it, so any insight would help. I think its a bad relay....?
