Thanks for the tip rumpig. Got the ecu and the airbag ecu out. They were both covered in a layer of fine dried mud. Pretty piss poor of nossan not to seal the ecu i reckon. I know its not meant to go swimming. But for a 4x4 and how piss poor the sealing was these things happen. For the sake of a couple dollars of resin. Considering how low they are mounted. Fingers crossed they work a treat after that clean.

Transfer case and gearbox were full of iced coffee flavoured oil haha.

Done the test run this morning. Running like a champ! Thanks for the help guys. Done a search on the forum about how to reset airbag light. Success as well! Love the forum.

Cant believe how the ecu has no sealing at all. Tempted to pull it back out and pour resin over the board. Thoughts?

Not that im planning on drowning her again. But i am a bit of a donkey haha

The ecu board does get a coat of lacquer on it to prevent oxidation.
There's an atmo pressure sensor in them so they can't be air tight.

Mmm a degrading ECU board is not ideal
Likely to cause issues or strange behaviours down the track
The dreaded "Electronic Demons" woooooooooo

You can get Urethane seal coat in a spray can. Its amazing stuff
Spray it on circuit boards, fine wiring etc
I have a vintage Toshiba desktop fan that was tripping the safety switch in my house because the circuit board inside was a bit greasy and brown
Sprayed the board with this gear and viola no worries
Also sprayed the ECU in my 98 mazda bravo because it was playing up. They have capacitors that are known to leak a bit
It fixed the misfiring i was having immediately

Cant recommend this gear enough

Was all going good. Then started getting the hard starting a few days ago. Tacho going erratic. CEL coming on once started. Can get it to start quicker without throwing the CEL if i use a little throttle while cranking over.

Today i pulled the ecu. Cleaned again and got some clear laquer coat ecu board protector. I tried to get that crc urethane you mentioned but no one stocked it. Gave up and got the laquer from jaycar. Pulled a couple of earths cleaned and out back. Didn't seem to help. Then thought ide give a hit on the trickle charger. was sitting around 12.3V when i plugged it in. Left it on a bulk charge for a few hrs. Got it up over 13.4 before i went out. Was back down to 12.9 after i got home. Cranked over amd stsrted alot easier and no CEL. Ill check again over next few starts.

I know absolutely nothing about the magical pixies that make batteries chooch. Was my battery low? What do these things like to have to crank over.?

Ive read a few threads talking about starter motor and glow plugs being possible causes. Anyone else have some odeas for possible causes?

Cheers guys

How does it run once started? Mine was cranking quite well but the tachometer was jumping around as it did then the CEL would light up. Once started it ran fine with the engine light on. Occasionally it would start without the light coming on. I changed my starter and it fixed straight up. Turns out the tacho shouldn't move at all until the engine is running (well that is how mine goes now anyway). If it is rough after starting, probably not the starter

Yeah runs perfect once running.

Ive got it starting without throwing a cel pretty much every time now. Using a little throttle. Im leaning towards starter motor.

A quick look on ebay there is a pretty wide variation in prices. Anyone have luck with the cheaper options or stick to oem replacement?

Are they a servicable item can they be repaired by a specialist or are they throw away?

I got mine from Repco when they had a 20% off for Rac card holders for around 220 I think. I figured for warranty if I get stuck anywhere I should be safe for a replacement
