Hi Guys, Thanks for the ideas, Cam timing checked out ok but cam sensor seems to be giving no output. I actually have a new sensor but here is the problem:- The original sensor has been superseded, the new one has a connector on the top instead of a flying lead, there is an adaptor lead listed but they are on back order with no delivery date! Has anybody got the pin outs for sensor part No NSC 000310L? With this I can make up a lead from the old sensor even if it is a temporary one.
