I have a 84 toyota xtra cab FI 4cyl. I got the truck from my uncle for nothing. It had a blown engine in it when I got it from him. I later took the engine from my 88 yota and swapped all of the FI over to that motor and dropped it in the 84. I have no power except when I jump wires on the ignition switch. No headlights, park lights work when they want to, and starter just clicks. When I removed the starter and checked it on a jumpboc it worked like it was suppose to. Any help would be greatly appreciated.
