Hi all, Having sought help a while back overcoming startup problems I am back again after being stumped by yet another problem.

Helping my neighbour after his vehicle broke with what was initially thought to be ablown head gasket grew somewhat when it turned out to be a cracked head. Obtaining and fitting a replacement head took more that the production line fitting time. It was also pepered with a rash of ever other type of problem not least the weather over these past many weeks. The vehicle initially broke down in July 2013 and has stood ever since. I now believe that although the vehicle was in good order until it broke down when, attempting to re start after fitting the replacement head failed miserably. It was wanting to go but was clearly not getting fuel. Help was sought and eventually after much checking of fuses, supply, and imobilser etc, fuel was eventually delivered to the injectors and the engine now starts and runs well. But alas the spill line is being pressurised fron the pump body connection. The line back to the tank is clear. My guess, and I am clutching at straws, is that the cut off valve was stuck closed and caused the initial lack of fuel and now not fully open is allowing pressure out of the pump body connection which is shared by the spill line fron the injectors. Anyone out there got any ideas which would help to sort this one please. The Nissan approach to help in such matters does not fit in the real world, have the vehicle brought in £180, run diagnostics until the fault is traced at £75 per hour.
