I have a 97 4Runner (4wd, 6cyl)....about 10 days ago I started having troubles starting my truck. I replaced the ignition switch and it started right up a handful of times then started having issues again. I replaced spark plugs, ran smoother when it would start, but still not starting well. I then replaced the starter contacts and it fired right up and runs smoother than ever before. Then about 2 days later I stop at the store and come out and the truck is dead again, won't jump start and I have a few working light (dome, door open light and ding), but no other dash lights. I find that the AM1 fuse is blown and replace it, again 2-3 days later the same fuse blows again. I am assuming I have a wire grounding, but am having a hard time finding anything that looks like a problem. Anyone have an idea what wires I should be focusing on and if there is anything that could have caused an issue when replacing the starter contacts? Thank you for any input you may have.
