Temporarily fixed my truck woohoo!!

[AlexD333]

I am a happy happy chappy!

Went for a spin before picking the missus up, truck misbehaving as usual, I stopped and parked up, got a big big can of 2040 lubricant and saturated (really really saturated) al the electrics around the intercooler and the cps plug and the earth by it and some earths by the coolant bottle and earths and plugs on the passenger side, along with glow plug connectors and relay ect ect.

I also sprayed the hell out of the throttle pedal wiring (but more gentle) and also a really good spray of the ignition barrel

I went for a spin and she felt hesitant for a few seconds, then better, then hit the motorway upto 65mph and no lights on (before it was 20mph plus)

Couldn't go any faster due to london traffic, will have to test tomorrow from cold.

All signs pointing to electrical gremlin which is sort of great news

Fingers crossed youve got some progress Alex

Well, I believe this certainly identifies that there is a faulty electrical connection, spraying the wiring heavily has obviously caused the broken/faulty wiring to bridge better connection :nenau

Perhaps someone will shed light on another theory :nenau

 

[Sweety]

Well as that has helped it points to bad connections so you will have to start cleaning up all the engine bay earth's & wiring connections before things get worse:augie just do a couple a day & you'll soon get through them all:thumb2 BTW Rick's garage is closed over Xmas & New Year:lol

 

[Fez_uk]

Why are you using lubricant on switches????

 

[kitchenman]

If the fault returns spray one group of connections at a time then test drive until you have the problem isolated, then sort it properly.

Yes, well I'm actually visiting rick this weekend so hopefully he can work his magic and fine the bad egg :bow

Yeah I've been lucky managing to visit rick just before Xmas. I'm hoping to rectify it as I must see family down in devon, it's a birthmas celebration, mum born on 22nd lol :lol

Spanner in the works time coming up
You may actually have a perished vacuum hose and the "lubricant" spray has sealed the pipe.
I've had years of muddy abuse all over my engine bay and electrics. Never an associated connector problem I'm aware of. Those multi pin connectors Nissan use are as good as water tight in my experience
As said above though, try one area at a time or you'll still be in the dark as to what you've fixed. Good luck though :thumbs

 

[elty001]

Fingers crossed with it mate.
Nothing worse than an intermittent fault you can't put your finger on.

 

[AlexD333]

It's bloody awful. What are these vacuum hoses then? Where can I check? :thumb2

 

[briggie]

depends what you have sprayed it with :augie , you could have actually made a connection that was intermittent

 

[makeitfit]

Just check all the little 6mm vac pipes. they work stuff like egr, waste gate, etc There's a multi block of actuators on n/s wing under air box ish. Have a spy at them and follow them :thumbs Worth a check

In the past any welding or grinding work in the area can perforate the small vac pipes too:eek

Will be a good day to book your MOT, as you will more than likely get the day and time you want. You can always cancel later.

 

[AlexD333]

All great comments, thanks chaps, Yes EGR is blanked, but lots of grinding has taken place around the bonnet area for bumper ect so its possible a loose fragment has come off.

I suspect what Briggie is saying is on the money.

Are these 3 actuators like electrical blocks on N/S wing? in line with each other?

I remember spraying through one of the vac hoses on the offside and the lube came out the top of one of them :lol (with no symptom change I should mention) :augie

 

[AlexD333]

Tested the terrano again from cold, repeated the spray before I started it up to make sure it wasn't a hot fluke, fired up, no coughing and instant power as before it would judder up the road badly when colder.

The other thing I noticed as I like to do the glow plug trick 2 or 3 times is when I turn the ignition off I now have the buzzzzzzz back (I believe from the glow plug relay) before I sprayed away it was just a dull click.

Where does the glow plug relay earth to? This is what I am suspecting? :nenau

the glow plug relay should not "buzz" so you could be right, but the relay earth will not pull much current and the plugs themselves earth through the block, we will have to trace the wires on Sat, Rick

 

[Sweety]

Funny I get a buzz sound if I switch the ignition on & turn it off without starting the engine up & it seem to come from the o/s wing area:nenau thought it might be the relay for the plugs but mine has always started ok but I think i've got a plug that's gone down now:doh

 

[solarman216]

Doubt it is the glow plug relay, Rick

 

[AlexD333]

Perhaps another quirk of the later models? :nenau

It's about a 3 second buzz if the ignition is turned off. It's always been "normal" on mine.

It was not doing this with the running issue but is back doing it again (which I believe is a good thing) :lol

 

[AlexD333]

The only reason I found this out what when glow plugs were naff,i would warm em 3 times :thumb2
