Terrano Diesel Pump

[thecrazycabbage]

As some of you know, my truck has been unwell for a while.

Stealers say its a little 3 pin unit held on the diesel pump with sheer bolts.

Apparently, this doesn't come seperatly.

Diesel pump part number;

167001f200

Mk1 non intercooler (square headlight) Terrano II, mechanical pump.

Thanks in advance guys!

To be fair mate I'd go for another pump

I can see if I can get a price for a replacement for you from James

[thecrazycabbage]

That would be awesome if you could!

FYI..here's a link for the Zexel VRZ (Bosch VP37) IP service manual in PDF.
It may only serve to confirm a replacement pump is the way to go!

Although a fantastic piece of information, its not relevant to my pump.

Thanks anyway, but i think a pump replacement is on the cards anyway.

Unless someone knows how to remove/bypass the immobilizer unit on the pump, that is!

BTW, nissan part no: 167001f200

Bosch: 9460610791

Is yours a 3.0L (ZD30) engine?

[thecrazycabbage]

Is yours a 3.0L (ZD30) engine?

Negative, its a 2.7TD (No intercooler, the Mk1 T2), cable operated weasel pump

[rayf3262]

In that case there is no immobiliser on the IP, it is not coded to the ECU and can simply be swapped.
The only thing the immobiliser can do to a VE37 type IP is prevent the fuel cut off from operating, which can easily be bypassed.

As far as I am aware there are 3 basic IP's used on Terrano's:
1) VE37 / 2.7L mechanical throttle
2) VP37 / 2.7L fly by wire throttle
3) VP44 / 3.0L fly by wire throttle. CAN bus controlled and coded to ECU.

Hope it helps.

Interesting.

The stealers code read mine, and reckon its the immobilisers unit on the IP that's the cause of the fault.

I have tried giving the cut off solenoid a direct live feed, it clicks, but still doesn't start.

Im not sure what to think now, ive been told so many different things now - do i need a new IP or not? What is the 3 wire unit on the IP thats held in by sheer bolts that the dealers reckon is the problem, and how do we rectify it?

[rayf3262]

Even the VP37 fly by wire IP has no immobiliser, the fuel delivery is however under direct ECU control, so if the ECU says no go that's it.

IF your IP is a mechanically controlled IP (VE type?) and it has a 3 wire connection plus the shutoff solenoid, I am afraid I am unsure what that is.
I admit that the fact that you have an ECU that controls a mechanical IP is confusing.
That said there are variants of the VE pump (VE-EDC and VE-MV) that dispense with a mechanical throttle and do use an ECU to control fuel quantity.

[thecrazycabbage]

o.0

That 3 wire 'thingy' links to the IMMU (or so i have been told) On my model, the ECU only seems to operate the EGR valves, although there was someting about a fue delivery valve in addition to the 2 above valves, but i believe these were on the Zexel flyby wire pumps fitted to the TDI's

Rang James and he only has complete engines.

That's the trouble with these engines, I find because they are so bulletproof no one breaks them as they come out of either crash damaged vehicles or ones that have failed MOT due top not being able to be welded anymore

He does have some Fuel Pumps for 2.7 TDi's and 3.0l ZD30's

[davenclaire]

haveing spent the last couple of weeks investigating bosch ve pumps im sure the wires are todo with egr operation and cold start sensor the dealer is wrong there is no immobiliser on any of the td or tdi injector pumps

[rayf3262]

I think davenclaire is on the money there, its a feedback potentiometer for EGR control.
The so called ECU on these units are only there for EGR (emission control) and should not prevent the engine from starting.

[thecrazycabbage]

Right, so there is nothing on the fuel pump that is tied to the IMMU unit?

Ok, so how does the immobiliser work on these vehicles, as simply giving a direct feed to the cut off solenoid doesn't work?

[rayf3262]

Not sure exactly how relevant this is but,... from the difflock forum re LR 300Tdi which uses same VE type IP:
[/URL]
could alos be a non edc, 3 wire version.
Land rover used this on later 300tdi to stop them being so simple to steal. when my imobiliser messed up, i removed the black box with the 3 wires going into it with a chisel. behind all that is the normal stop solinoid with 1 wire which i ran a ignition live to

Sounds kinda easy to bypass.

I shall report back when i have more info then!

=)

[davenclaire]

i new i read something on the web about this as i originally thought the 3 pin unit on the side goes to the internal temp sensor and egr control it also has a direct effect on timeing some how, the temp sensor is replacable here is a photo of it
says i cant attach it again have a look on my post leaky injection pump you can see the temp sensor where i have removed the top cover

[davenclaire]

this clearly shows the fuel temp sensor that i think is causing your problem its right at the end of the clip

or an even better view and discription

[thecrazycabbage]

I appreciate your input, but the part th e dealers were referring to is on the outside of the case, has 3 wires to it, and is held on by sheer bolts, bolts whose head snaps off when you get them tight, pretty permanent anti tamper.

Gunna see if they can get the pump off if I can pick it up and see whaats under that cover.....pics when I get them!

i will pull it off tomorrow from the scrap pump iv get here and let you know

[thecrazycabbage]

The black plastic thing? Awesome! Try not to splatter it too much, I may need whatever it is!

[davenclaire]

ok have taken off the black plastic cover with the wires attached and as i thought as this pump is for the TDI its just the electrical connections for the electronic acuator/throttle and cold start sensor.

infact the 3 wires on there own are the stop solenoid wire, fuel pressure sensor and something else yet to work out what so this pump i have is no good for you as its the TD

im still at a loss im sure all you have on yours is pressure sensor, cold start, shut off solenoid and something that goes to the EGR?

look on page 320 EC section of the manual it shows the pump for the tdi but clearly shows the injection timeing control valve and stop solenoid the only other wire you should have on yours is the cold temp sensor


strange i cant find the td pump in the downloaded manual

[davenclaire]

search and ye shall find

http://himama.livejournal.com/pics/catalog/1591


some very good photos here you can clearly see every bit of the injection pump and associated parts it looks like the part they are saying is faulty is the speed controller/actuator if this is the same as your pump then its easy to change if you can get hold of a scrap pump

[thecrazycabbage]

http://himama.livejournal.com/pics/catalog/1591/10901

It appears to be the plastic thing on the bottom of that pic, if its the part im lead to believe.

No idea what it does, however, it looks important, so i'll try to stop the stealers breaking it off tomorrow!
