Unhappy Mitsubishi Space Star, No start.

Mitsubishi Space Star, petrol 51 Plate,
Customers complaint, no start, had the codes checked and came up with crank sensor, fitted new sensor, but still on start.

I started to check this out, and a code is set for the crank sensor, there is on spark or injection op:.
On a scope test the outout is 12v and no sig:, this is a little odd as the supply is 12v and the output is 5v, the ground is 0v, and when i say 0v it is Zero, and you dont see Zero on a working ground line, it makes me think this is just a bit of free wire.

I also noted no sig: at the cam sensor also, on removing the crank sensor plug, and testing the volts at the loom end in the output, i noted 5v, but put the plug back on and this will rise to 12v, i now know there is no ground to the cam or the crank sensors.

This is on the black cable cam and crank sensors, this is to the ECU, and canbe found in centre by the gear lever.

We removed the box and the PCB, and here is the fault, blowen out ground track on PCB see the photos.

Here is the blowen out ground track.

Just here.
