Recently aquired a 97 LS 400 With 96K on the clock. The car had a miss. I installed my Blue Driver bluetooth code reader, and it worked perfectly. Showed #3 cylinder miss. I found a cut in the plugwire, siliconed and taped to repair and the miss is gone and there were no codes. So I do know that the Code reader will work on this car.
Now fast forward... I drove the car to my paint guy to have the rear bumper refinished. It was a trip of about 65 miles. Car ran perfect at 75MPH! About a mile from the shop the car started acting like someone was turning the key on and off. When is would cut off the CEL would start flashing. Well after I got there. We went to move the car and it crank, but no start. I put the code reader on it, would not connect. Called Blue driver, they gave me a different sequence to connect the code reader.... still no connection.
So I called my mechanic he came over with his Tech II computer. And it would not connect. The OBD port does have power as the blue light on my blue driver will illuminate when plugged in. So what's the answer? ECM failure? Appreciate any help. Thank you.
