I had told you about my problem with my Saturn Vue. I got my ECU yesterday and installed it. Started fine for 3 seconds and died. After 4 attempts I realized that the key had to be programmed so I did the procedure and 30 minutes and 15 seconds later.... she's running like new,but, My fans don't speed up when I turn on my A/C. I disconnect the coolant temperature sensor and they speed up. What could it be????
computer failure does just that. I assue you got a used or "rebuilt" computer, only brand new ones ever really work well
