Well heard back, no faults found sensor wise but they said the fuel hoses where wrong way around, I personally can't see how it would start and drive at all like this but my knowledge is low so they might be right, does it sound plausible? They have taken it for a run and said it drove fine without issues. They are keeping it over night to see how it is on first start tomorrow and will give it another run, all going well though should have it back by lunch tomorrow all working with such a simple fix.
