Can you tell me if the fault relating to the sensor change is or is not a tell tell sign that there was a problem with the timing chain along with the other evident issues like misfire, and possible water pump issue? Or is there no sign that the technician could have noticed of the timing chain about to snap?
there wouldn't really be an issue to suspect the timing chain based on this
What I mean is, I had gone in there explaining that I had recently purchased the car, I was not sure of the history and that I wanted a full inspection of the car... so there is no way of the technician picking up on the timing chain failure?
it depends, if it was making noise or was loose and causing debris to collect in the sump, then yes, but if it snapped randomly, no
Also,,, will the car run if the timing chain had broke on the test drive or it will of had to have snapped on start up?
car will not run without a timing chain
