Hi all I am a UK Terrano owner with a 3 ltr zd30 engine in for repair, and am told you guys are the people to ask, it is the none common rail engine, and starts easy but hunts bad at about 2500 revs and above (when I say hunts) it is like the ignition is turned of for a few milliseconds then on again, a few seconds later it does does it again, is this the spill valve on the pump or could it be an external problem, like connections, I ask this as no fault codes have been generated at all, and I believe a 78 would be for this fault, but I also understand that the pump has its own processor which may not be in communication with the ECU, I have eliminated all other possible problems as far as I can tell, hope you can help, but do think it is probably pump in which case the motor is probably not worth repairing, Rick
