    So I have an 02 tree 275k and the other day started misfiring, running rough on the freeway, checked codes had p0300 and individual misfires on 1,2,3,4,5, and 7, after 2 weeks of messing with it now I’m down to p0300 p0303 and p0306. Can’t get the misfire counter on my scan tools to work w my truck for some reason, someone told me there could be a software wall? Whatever. What I’m looking for is an ecm pin out.. trying to check for voltage at injectors. Was able to find a tundra FSM online to download but the ecm wiring is different
