help with fuel pump noise ?

[Nav 4X4]

Hi, I hope someone can help with info.

I have a 1993 navara 4x4 with KA24e engine and occasionally, but not always, when Ive been driving the vehicle, then stop and turn it off, then about 5 minutes later, I hear a sound coming from the fuel tank, it sounds like an electric fuel pump, and it goes for about 10 seconds , then it turns off.

this is really strange, the ignition is OFF when it does it.

the first time I heard it, I got under the car and tried to figure out what was going on I couldnt believe it,..Now Im starting to think it may be normal for this to be happening?? can anyone help please.cheers.

With no responses to this thread Im now thinking nobody else has had this happen? what are opinions, does ppl think this is normal or sub-normal???

Is navarra what they call the pathfinder down there? I don't think anyone in this forum even knows what vehicle you're talking about, especially since you've got something I've never even seen. Is that a diesel?

Navarra is the Australian Nissan hardbody pickup in earlier years, and then the USA equivalent to Nissan Frontier in later years.... You need to talk to Nissan Hardbody people as it is a different animal from our Pathfinders (Nissan Terrano in your country) I coped your question here, you should have replies soon http://www.4x4parts.com/ubbthr...58789

Yeah, I saw that. They're pretty hardcore about their engines on there. I got curious and started looking and didn't have to go far. Didn't know that's what they called a hardbody in OZ. Curious

Yeah, I think you guys call them, D21 pick-up,.. so did you guys ever have a Navara, as such, Im thinking possibly not.

anyway that noise Ive got, someone the other day said that sometimes the fuel cap makes that noise to release preasure build up in the fuel tank, Im thinking thats probobly it!! which is good, no money to spend!! yaaay!
