ZD30 Fuel Pump

[danielrusty]

Hi there folks,

Would greatly appreciate any words of advice regarding my Nissan Patrol GU 2000 (ZD30) which ive already commited to spending lots of money on and to only be hit with another yesterday. I've had the diesel gas fumigation kit put in and as well as a 3" exhaust and so have eliminated all turbo lag and has made the tractor a responsive and awesome sounding vehicle with some serious grunt, however i turned my vehicle on yesterday and the engine warning light came on and there was virtually no power at all. I managed to drive her a short distance to the Nissan mechanics so they could run the computer scanner over her and the code she's throwing is P7 which has to do with the Fuel injection system. As ive had the gas put through her, Nissan wont go near her and so i called United gas and mentioned the code and that it was a ZD30 and he said that he gets them in all the time. Its most likely the fuel pump gone and she's about a $2500 job to get fixed. WHOA!! Oh the mechanics at Nissan said that they believe the engine is being starved of fuel and i only managed to get it to the mechanics on the small amount of gas.

Can any one shed some light on my predicament??

Also, for you ZD30 enthusiasts, could u possibly explain to me why this has occured. Has the gas system brought this on or is this just one of those things??

And lastly, in the worst case scenario, cld anyone recommend a diesel/gas specialist in perth who would know how to deal with this kind of problem.

Thanks in advance, any info is greatly appreciated again

Nisaan Patrol GU II - 2" Dobinson Coils & Shocks, Safari Snorkel, 3" Exhaust straight through, Diesel Gas Fumigation Kit, Roof Racks & 60 ltr Engel and looks like a new fuel pump too.....

i don't know what they mean by P7. ive only got the dtc codes eg DTC 0707.

if its fuel problem i would first check for fuel blockage (fuel filter) and also check for air leaks (put clear hose on pump outlet). both will throw the same IP failure codes.

edit: google code its "P7-F/INJ TIMG FB" which i think is the same as DTC 0707. common cause is air leak or restriction in fuel lines. it can't achieve timing so throws the code. worse case is worn timing piston in the fuel pump. tho i have heard of weak fuel reg spring in pump can do similar.

Its a code that generally indicates pump problems. However before you committ to 8-10 hrs of labour to r&r a pump, also check for fuel retrictions and air in the system. Check all wiring between the pump ecu and vehicle ecu. Ask united if they can get codes from the pump ecu to determine there is a fault.


It happens sometimes for no apparent reason.

Also check if the glow light is on the dash. If there is no light you have a blowen ECU fuse. There is one under the dash & a few under the bonnet. I have heard nissan dealers who have fitted 2500 grands worth of pump to find out later that is a 50cent fuse
