I have a 2002 Toyota tundra with over 200k miles. It was running just fine,I went out of town for 13 days. I asked my neighbor to please start it and let it run every few days . Upon my return from my trip I got in my truck to find the battery dead,got a jump ,it started so I went on my way. About 10 or so miles it began to overheat. I pulled off the road had my neighbor come to see about it. He brought water, I proceeded with my errands, while in route going back home the truck began riding rough,then felt like it was misfiring. I couldn't imagine why suddenly my truck began having all of these issues since It ran perfectly fine the day before I left for my trip. So we ran diagnostics codes random misfire came up,then noticed radiator cracked along the top. So far now the coil packs,fuel injectors,valve cover gaskets,head gaskets,fuel pump have been replaced. The radiator is in the process of being replaced at this moment. The battery has been removed during all of this. I'm nervous about the upcoming end results. Is there anything I need to know about after putting the battery back in and connecting it? Like a reset regarding the computer or anything?
