Does anybody have a recommendation about getting my ECM repaired. My donor vehicle was a 99 4Runner with the engine immobilizer which I have the original Key and transponder amplifier but has recently refused to start. Is it possible to remove the immobilizer function? I've have another ECM that has never started this truck so I'm guessing it also has the immobilizer. My third ECM came from a 6-99 on vehicle and will start the truck but throws several transmission codes.Thanks
