Took apart ECU's,injector drivers were cooked on all 3,very visible. :shock: Even changed the engine harness once.After those 4 parts,the tech that got it last,called me and asked WTF.Toyota tech line had no clue either,car was in the dealer for 6 weeks.I happened to have a core with the correct injectors,plugged them and another ECU in and all is well.I just happened to have my injector cheat sheet with me that day,and we gave it a try.Maybe we were just lucky.williamb82 said:btw shawn, were they positive the ecus were bad, or were the injectors just not firing? i can see the ecu being good in this case and just not having the current to fire the injectors. which i guess to them prolly looked like a bad ecu. espeacially if they didnt notice the screwup.
