I have what appears to be a complete computer failure on 2007 Patrol auto. Early intermittent symptoms glow plug light not illuminating on cold starts. Later the loss of fuel pressure in fuel line. Then the faults become consistent. Further symptom when idling engine would not rev when accelerator is pressed. Now the engine will not start and when computer diagnostic reader is plugged in it will not read the computer. Several other diagnostic reader where used with the same result. Appears computer is not responding.

This a quick summary of the issues, wonder if anyone has experience or heard of this or any clues.

Thanking in advance of responses
