Rightio…

So I replaced the Starter motor on my 1990 GQ TD42 ute. Started fine and worked great.
Next day, I went to glow/crank the engine, upon turning the key to crank there was a clunk and then nothing.

Turned the key off and back on, only to find that there was now no power throughout the whole car (lights etc KAPUT), but that a relay was buzzing behind the battery box.

Investigated to find that it is the glow plug relay, so I swapped it, and the IGN (start) relay out for good measure. Replaced the 2 relays and had lights etc. again. Upon trying to crank however, done the same thing as before.

I checked the battery. It has 12.6 volts in it, so I don’t think its a worry, and is charging fine as well (threw it on overnight).

It gets even better when I find that when you unplug the glow plug (plug in front of the airbox on the intake manifold) from the Bus-bar (rail between your glow plugs) that the GP relay stops buzzing and seems to throw in and out as you would expect. Also that the soldered white with red striped wire onto your start relay doesn’t have power (I assume this would be the ’86′ part of this relay, with the 30 being the direct battery feed onto the stud terminal)

Have replaced all fuses in drivers side kick panel, and checked for power at the back of the IGN switch (has power) but no results throughout the car.

It gets even better again when I find that sometimes you get all lights working again fine, as if it was just any normal TD42, and then you attempt to crank followed by a large clunk and a massive arc from the plug into the Bus-bar if you have left it unplugged.

I get the feeling this is a combination of a shorted armature, and a buggered ignition switch. Thats what I am hypothesising

I’m a 2nd year auto electrician, so don’t be afraid to throw technical terms out, but this is just doing my head in… It’s probably something simple, but with all the stress (car has been off the road for 14 days attempting to fix this) I am worried I may have overlooked something, or the people with more experience may know a few tricks

Before you give me a serve about being a 2nd year apprentice in auto electrics and not being able to fix my car, I work away for 7 days on, 7 days off, and can’t exactly take the car into work to fix it

If anyone is able to give me some feedback it would be heaps appreciated…

I’m really missing my truck, and are going mental without the old girl

Hey All,

I am just about to change the water pump and hoses on my 2.8 and I was wondering how hard it was to change the water pump?

Do you have to take off the timing belt etc to get the pump out?

Cheers

Just wondering if all rocker covers have (Nissan) written on them in the silvertop models?? Cos mine don’t :/

Here is my problem; towed a trailer for 800kms with a couple of beds and boxs (not much) at christmas and was running a little hotter (about 85c) than normal (normally about 71) was in 4th gear 3000rpm at 95km/h ish no a/c, the next morning doing my daily fluid checks i found the overflow bottle still full so with a little more investigation the top return hose from the engine to the radiator was empty and there was mud/muck under the radiator cap. I put that down to pulling the trailer as it has never happened before, however i just did a 500km run with no trailer ran at normal temp the whole way with the a/c on even when i wound it up to 120km/h and it now still has the same problem.
Any help/suggests/solutions would be áppreciated as i’m 2 hours from the nearest parts/service shop

From ebay – just checking before I spend my hard earnt:

Thanks for any input.

I’ve just been offered a TB42E motor to replace the old one in my patrol. The question is while mine is the old carby engine the new motor is the fuel injected and electronic ignition one what is involved in the conversion. As my engine has really low compression on one cylinder, loses water and now sounds as if a bearing is on it’s way out should I just swap the bare engine and continue using the carby and LPG setup.

Has anyone else done a conversion from an old carby and points TB 42 to the electronic injection and ignition unit before and what other things will I need to buy. I guess I’ll need to buy a new fuel pump but do I need to run new supply and return fuel lines?

The guy who has offered me the motor is in the process of installing aVH41 into his swb Patrol, but before taking the motor out i took the Patrol for a run and the engine seems ok, more power than mine and doesn’t use water.

Does any one know If the two temp sensors on the RB30 carby manifold can be obtain after market? part numbers. Also which does the engine temp? and what is the other for

As the trident books dont list any

Please help me a lot of people telling me different types of oil to put in my Patrol. Which is the right one for this engine. It is manual gearbox 1995 year model. Non turbo.
