Engine fault codes

[CrossCountry]

I've got a 2001 ZD30 that was running fine then spluttered a bit and just stopped. I recently installed a boost gauge and EGT gauge as suggested in many discussions and have found te boost and temps to be running fine.
I checked the codes using the engine light on the dash and found 47 , 76 ,73 & 1401.
The manual I have says the 47 is a Crank position sensor which I was told was the problem, but after replacing , still no go. The manual dosen't have codes above 55 but I was told 76 is a spill valve problem which I guess is in the fuel pump. I cleared the fault codes and cranked again resulting in just 76 being the error code now.
If anyone has any advice I would be very greatful.
At the moment it's booked in to Nissan to have the problem further investigated and quoted.

Greg.
