Electrical Problem Still Not Solved

OK Gents.... I have still not managed to solve the electrical problem. It's very strange and I will try and explain here the best I can.

Starter motor turns, but the engine does not start. Everything seems normal, except the glow plug control lamp does not turn on when I Turn the key.

Today I tried to give the glow plugs power directly from the battery + terminal, as suggested by Solarman. I had high hopes for this. None the less, it did not made the engine start. I thought it would work, because when I attached the wire to the glow plugs (as described by Solarman) I saw some sparks at the terminal. Basically I just pulled the plug with the white/blue wire and ran a wire from the battery + to the glow plugs. See pic below.

I think the main problem is that the glow plug relay (see pic) does not get any power. The relay itself works fine when I give it 12V, but there are no power on the blue and yellow wires which should activate the relay.

Here is the layout of the engine compartment fuse and relay box. All fuses should be good according to my multimeter/ Will test again.

My multimeter says this "fuse" is good.

I am starting to think it might be NATS playing tricks on me and my normally very reliable Terrano. Even if I let the starter spin for 15-20 sec. there are no signs of the engine even attempting to run. This is becoming a serious problem for me actually.

Thank you for your time Gents :thumb2

Cheers!

I know exactly what you are describing, my Terrano does this to me only if I leave the ignition on for any longer than say 5 minutes without actually starting the engine.

You kind of just know that's what it is after a few years experience and know to just turn off and start again. The tell tale sign is I find my start spins over a tad faster than normal and doesn't sound as laboured as usual if that makes sense.

Here's one to try!! Have you got another key you can try?

I actually have 3 keys and I have tried all of them. I have also tried to turn the key into the position just before the "Start", leave it there for 10 sec and then try again. This helped once when NATS made a problem after the battery got completely discharged. I have never seen the glow plug light not working though.

I talked to a friend just now. and he suggested me the same as Solarman. Give the glow plugs power directly from the battery. He said it should make the car start. Since it does not, he thinks the glow plugs are not working. His thinking is that I might have been running on 1 or 2 glow plugs for a while, and that they have finally given up too. I just wonder why the glow plug relay does not get any power.

In theory the engine should fire up without the glow plugs, right?

Next thing I would do to 100% make sure that the immobiliser is at fault here is to try and start it with easy start but in fairness, even if all 4 plugs were down, as long as your starter and battery are good then it should start eventually, even I was managing that with Veg, so even easier on Diesel.

I'd be tempted to crack an injector whilst someone turns the car over to see if you're even getting any fuel up there :thumb2

Do you mean this little guy If so, do I just loosen the "cap" and turn the engine? No bleeding of the fuel lines afterwards and all that good stuff? I'm not 100% top notch on Diesel engines... :lol

crack the union 17mm crank engine and diesel should spurt out of the top of nut if it does then fuel is reaching the engine and should start even if glow plugs are not working or a squirt of easy start or clutch cleaner down air intake will fire it up

No Fuel

Good Evening Gents

Fuel is not reaching the injectors. I opened the union on the injector closest to the firewall. No fuel spouting out.

I think the problem is a faulty relay or NATS.

Is there a way to "reset" NATS or completely disable NATS?

when i have had a issue with non start and no fuel i spray easy start or carb cleaner in where the air filter is remove clips have someone crank and spray a little in at a time to get it to fire i find that once started after a few min of it running i switch off and mine has been fine i had same problem with mine 2yrs ago i did this and it sorted out not played up since worth a try before having to get a dealer to work on it i was told that by doing this it resets it all not sure how true this is but i have never looked back and started many non starters this way with success

Thank you. The thing with having a dealer looking at is out of the question. The closest dealer is +250 km east, or +400 km west :lol

well try it and see if it works you will feel better fixing yourselve:augie

You say you have 3 keys, did they all work for certain? I ask this because when I got my SWB Mav it came with two keys, one was programmed the other was not, it was kept simply as a spare to enter the vehicle manually, however they got mixed up and after I tried to start 3 time with the bad key, NATS locked me out, the only way was to get a car locksmith to re program it, he simply read the key chip then programmed it back into NATS or something like that, took him about 20 mins but he had 45 min journey each way so the £60 he charged was not bad, you do not have to go to Nissan for this, incidentally on UK cars if it is a NATS problem the red alarm light flashes different on the top of the dash, not sure if you have that, if it is not a NATS issue then it could be the stop solenoid on the pump, have a look at Banshee's pump change thread, he has just put up a series of pics of his spare pump, Rick

 

[solarman216]

The thread is "Bosch injector pump swap" around the middle of the pics is one that on the casing you can see the the numbers 8 and below it 31 to the right of those is the stop solenoid with rubber boot over the terminal, see if you have 12v here, if not take the wire off and make it safe, then put a temporary wire to battery + via a 10 amp fuse, then crank it to see if you have fuel at the injectors, Rick

Yes, i know for certain that all 3 keys work with NATS. I have used them all, but use one as my main key of course.

I checked earlier on the NATS flash. It looks normal.

There is something tricky going on. No power to the glow plug relay and no fuel to the injectors

the two could be linked, do try the 12v to the stop solenoid if that works then you may have a "splice" that has gone bad, this is where Nissan spliced (solder joint) then wrapped it up in the harness, only way to find it is cut the harness open, there is a big one in that harness running along the inlet manifold, thick white wires joined together one of which is the main glow plug supply, and may possibly supply the stop solenoid as well, via a fuse and relay, I never could follow Nissan wiring diagrams, if Rayf is about he will know, or PM him he is a very helpful guy, Rick

Than you very much for your time and help Rick mate :thumb2

I know what you mean about Nissan wiring diagrams..

i was going to mention stop solonide but rick beat me to it,BUT TRY EASTSTART,it will fire up but if it does not continue running its lack of fuel,then EASYSTART it again the same if it does not run it confirms its not getting fuel.
feed glow relay direct,feed fuel stop sol direct from battery as well.
out of curiosity befor all this,take all keys out of ignition,lock car from outside with key in the door not pleb,then unlock with the key your alarm might go off untill you put key in ignition and turn to glow position wait 20seconds then turn to try to start.
if its no go then do the above.
press your fuel filter plunger down to confirm its hard to push.better still take off fuel pipe,its got arrows for in out,to injector pump near bulkhead by filter then press plunger and fuel should come out if not its not getting fuel there,open fuel tank to let air in then try again,keep pumping till you get fuel.
once fuel there put pipe back on.
then you can take fuel pipe off at the end of the injector pump get some one to press filter plunger and fuel should come out.
if it does replace pipe.
then if you have a bosch ip where the banjo pipe is attached on top of ip a long extension and socket,17mm i think will undo it ,be carefull as there are 2 copper washers,each side of the banjo,once removed there could be a small metal filter inside,remove it then get the filter plunger pressed again,fuel should come out of banjo,if it does replace not forgetting the washers. other pumps not sure where banjo is but rick will know.
so after ALL this checking it will start,but if not it could be the lift up pump in the ip pump so major work or the nats system.
as said crack an injector line and crank till fuel comes through.
the other thing is rig up a plastic bottle with fuel in it,hang it high and connect it direct to the ip copper pipe at the end of the ip.
this eliminates the hole fuel supply line.again try with easystart.
anything i have forgotten peps.
