which fuse is the ECU fuse that you blew? Ive had the same problem with my car, I put my T3 in drove it for a day and it sputtered and died. It turns over but wont start and I have already put new coils in and that didnt work. What else could it be? I feel for you though man cuz my car has been down for a week. I just got my BB T3/T4 in yesterday and my car doesnt even start so there is no piont in even swapping turbos yet. Didnt mean to thread jack man, sorry. Just need some answers.
