Hey I have a 2019 2.8D landcruiser commercial. A few weeks ago after about and hours drive i switched it off for about 45mins. Hit the button to start and no go. Checked the battery, plugged in computer, no fault codes. The head up display is slow to load. Trucked it to a garage, the starter is burned out so replaced it, still no go. Put a wrench on the crank and the engine is locked up. Took out the injectors to see if fluid had somehow got into the cylinder but no good. There was no vibration/smoke etc. so I have no reason to believe the engine has gone bad. The transmission was removed to replace the egr cooler about 18 months ago. it had seemed to be loosing power when under heavy acceleration, I though that may have been an issue with the turbo but I'm now thinking it could be a fault in the transmission that has now locked up the drive train i.e maybe a bolt or something in the torque converter, does anyone have any thoughts?
