Hi is there any way off testing a PTU as i have a missfire on no 6 and the plug is fine and i have swapped coil packs and the plug is still not sparking?? :bow:

Best way is to find someone local and check it with their working one. Dont know who is down your way tho .

Is there no way of checking the resistance across contacts to detect failier of circuit???

There may be, do a search on ptu and see what comes up. But I think that they tend to break down when hot, at least initially, so you would need to recreate the situation.
