Sub tank not transferring ZD30 CRD Patrol

[mhanly]

Hi all,

Bought a 2008 ZD30 CRD Nissan Patrol about six months ago and have not been able to get the sub tank to transfer to the main tank. When I select the sub tank button I do not get a light on the dash and have checked the fuse which is fine. Any advice on what the next steps are in the fault finding process would be great! Thanks.

Can you hear the pump running at all??
Mine works with ignition on but engine not running so makes it easier to hear..

I get no light on the dash in mine, but the light does come on the button when i press it....
I'd get under and check the wiring to the pump next to see if theres and broken connections.

A guy i work with had this exact problem. He said he took it to Nissan to fix and they did when asked how they fixed it they said it was fixed and not to worry about it. He drove from perth to Adelaide and the same thing happened. Went to the nearest Nissan dealer to get it looked at again. The guy he spoke to said disconnect the battery for half an hour then reconnect it thats all they do to fix it, Nissan don't know what causes it. He gave it a go and it worked. This was about 2 years ago he had this issue and i haven't hurd anything more about it. Hope Nissan have come up with a permanent fix.

the light on the Dash will only come on if you have a problem
when you press the switch, the light should go on, on the switch
it is very very slow to transfer

with mine, I find if I go to transfer when the main tank is 1/2 full, by the time it gets to 1/3 you start to notice the gauge moving and heading towards full

As BigCol said the light on the light on teh dash is a Fault light - you don't want that to come on
The light in the switch is the 'pump is on' light - you do want that to illuminate

If you have fuel in the sub and the main is less than 3/4 full you can check if it is transferring by pressing the sub tank switch (check the green light is on) and taking the main tank filler cap off and looking in the pipe.
A couple of inches down there will be a stream of fuel entering the main tank filler neck.

Try that and let us know how you go

The pump transfer rate is 1 1/2 litres per minute

I think it is as ET said the light is in the switch. in saying that I think its working fine
How do you know its not transferring, I again I think it is,go put some fuel in the sub
and transfer some to the main tanksitting in your drive way
