Truck won’t start, BAD PCM?
I was fixing my coolant temp sensor wires just now, and they started sparking when they hit the alt. I disconnected the battery but unfortunately the terminals layed back onto the battery. Now the truck won’t start, and I’m getting “no link” in scanner. Pretty sure I burnt my ecm up...? Also the mileage says “no bus”
i checked all fuses only one that was blown was the “cluster” 10amp, replaced that and nothing still.

Very possible. If the coolant sensor wires touched the fat wire going from the alternator to the battery it did create an unfused +12V to ground (the sensor is read to ground). There are two fuses for the PCM, #3 under the hood and #9 in the inside panel. Also check the ECM ground wiring from the ECM to the front of the engine if a ground wire burned up.

Yeah it’s what I thought, where do I go about getting a new one? I see some online that I give vin and mileage to and they mail it already plug and play? Any experience with them?
