D22 Immobiliser / Micro Filter problem!

Hi everyone!

Not many of you will know me as I am new here (My introduction post - http://www.nissan-navara.net/15-introduce-yourself/37217-selma-green-d22.html)

I have an old style D22 with a TD 25 engine.

On December 24th my car suddenly decided it wouldn't start at all!

So Far I have:

- Had the roadside guys out who think it needs a new fuel pump. The car starts fine if you squirt some brake fluid down the air inlet so its not a starter problem, must be fuel delivery

- No fuel coming out of injector lines, EVEN when you pump fuel through the system using the manual pump, which feels very stiff (almost as if there was a blockage in the fuel lines)

- Replaced fuel filter

- Replaced air filter

- Tried to bump start it whilst being towed fast

- Had it at my local garage who say it's an immobiliser problem but couldn't tell me anything more

- Took it to a Nissan dealer who say its the immobiliser solenoid in the fuel pump which needs replacing but they can't get the part anywhere apparently (after a bit of research, some people say it's a standard bosch fuel pump part which is the same on many cars?)

- Taken the Micro fuel filter out of the pump, as per some advice I received on here (Can't wait to get it going so I can see if this has made it faster but unfortunately didn't fix the problem - no fuel coming out of injectors still even with manual pumping)

It STILL won't start. I noticed the other day that the red LED immobiliser light on the dash is flashing when car is locked as per normal but is on constantly when the key is turned.

Does anyone have any recommendations on what I should do next? I am not too sure about how I could remove the part in the fuel pump as I don't know too much about cars, i'm learning as I go! If I could re wire this fairly easily, or just remove the part, I would be fine not having an immobiliser!

Thanks for all the help in advance!

Hi Fatha,

Thanks for the reply. I've done some further investigating tonight trying that accelerator pedal dance thing (reset the ECU?) But for some reason it's not working at all on my car? I tried it a number of times!

Thing is it has been at a massive Nissan dealer ship and surely they would have reset it to test it first before saying the fuel pump solenoid is bust? I am also not sure how to take out or at least access my fuel pump so I can remove the part which is stopping fuel flow? (see this thread I found - http://www.vegetableoildiesel.co.uk/mybbforum/archive/index.php?thread-9919-2.html)

I found a good thread on how to do it on the YD25 but not TD25Ti


I don't care about the immobiliser working in the future so if anyone knows if I can take off this solenoid or take a part out so it will always work that would be amazing.

Alternatively If I could find the NATS box and rewire it that would also be ideal (as i'm guessing the solenoid is not broken, just stuck due to the NATS system)

The red light on my dash blinks normally when key is out of the car or in off position but then turns to solid red when you move to start position and if you go further (to turn over the car)

If anyone has any other info I would greatly appreciate it. I have been searching for days about this problem!

Looks like I have a NATS 2 system which is much harder to bypass.

I found this video

But I have looked behind my glovebox, behind my radio /dash, behind my speedo with no luck finding a NATS 2 box. I did find a white box under to the right of my steering column which was for the 'remote locking system' but i'm guessing that isn't the same thing.

Apparently the NATS 2 system for a D22 is in the ECU so does that mean I can't get to it?

So confused about all of this!!!

How many keys do you have and are you using the same key all the time?

Is the remote control central locking working?

Was the battery (correctly) replaced in the fob recently?

It might be worth trying to re program the key before you go pulling any bits off, just in case it's forgotten it's not for scratching the inside of your ear........:-D

This might help.

Hi Hamlet,

Yes the central locking works fine as do windows and radio. I have two keys and i've tried both of them to no avail. The battery hasn't been replaced in either fob since I have had the car (June 15).

Do you think it would still be worth trying to re-program the keys?

I have noticed the battery is dieing quickly... Have to charge it almost every time I want to work on the car it seems

Cheers

Forgot to post this this morning:

Also, Nissan said that these are the 4 'codes' they got so I am assuming it has to be the Stop Solenoid as the guy on the phone said if all the codes are cross referencing to point to that it's that which is malfunctioning:

Fault codes:
1) chain chain of csolu-imm
2) csolu
3) Id discord , imm-csolu
4) chain of csolu - imm

Anyone got any recommendations? I was thinking of taking the solenoid apart and remove the actuator so it is as if it is always open? I can't find a replacement part anywhere!

Cheers,

The codes are relating to the solenoid and the key, and are all related through the NATS.

Whether the solenoid is not working or the key is telling the solenoid to not work would just be a guess on my part, but I think it's worth trying to reprogram the key just incase it's lost it's code for some reason.

As for the actual solenoid replacement, the fact that it's a different engine will make it a little more difficult to find the part but I wouldn't have thought it impossible.

I don't know much about these guys but I have seen them mentioned on the forum a few times, it might be worth giving them a buzz if you could get a part number off the pump they may be able to source a solenoid for you.

Again I'm not sure if the VP44 pump was fitted to your engine but generally these sort of pumps seem to end up on lots of different engines so parts should be available.
