Tb42e starting problems

[TJsGQ]

Hey all hey ya goin,
Ok we'll my 4.2 petrol injected patrol is starting to play up.. Just came back from a trip away n she ran fine no dramas at all with alot of frequent on and off starting.. Now I got home I started it n it didn't want to turn over tried it for a few seconds n no go than tried again n it started went for a drive turned it off n back again no worrys.. Tried it again next day same problem but got it started n it was fine to turn off n on when I went down the shops.. Any suggestions to what be causing it to really struggle to start.. Had no problems at all with starting it before.. Thanks in advance

Bit hard to tell from your description, does it sound/feel like an engine problem or an electrical issue?


Tip tip tip......tap tap tap....

[TJsGQ]

Well it runs fine just won't kick over when I try to start it.. Sounds like maybe engine because it just sounds like its struggling

[Yendor]

Did you play in any mud/water on your trip?

[TJsGQ]

Na was a real soft trip but maybe a week or two before there was a pretty deep bog hole of mud I had to go through.. But no dharma's for 2 weeks after that..

[Yendor]

If your engine is not turning over fast enough when cranking.

I would start by checking and cleaning the battery terminals, also check the main earth connection to the engine and power connection to the starter motor.

A good indication of a bad connection is heat, so after you have tried to start it a couple of times have a feel of the connections.

Also check your battery, most auto electricians or battery suppliers will do this test for free or you could try connecting a jumper battery.

If all the above are ok, you more then likely have a problem with your starter motor.

[Parksy]

Check your battery voltage, anything less than 12v and I'd be looking at a new one. While running should be around 14 volts. I'd be checking cable connections for corrosion and poor contact, bad earths usually cause poor starter performance. Failing that, starter solenoid/starter motor could be on its way out.

Edit, already mentioned, doh.

[TJsGQ]

Ok thanks you heaps for your advice ill try all of that tomorrow and let you know how I go.. Thanks again

Any tips on cleaning corroded battery terminals..?

Any tips on cleaning corroded battery terminals..?


Bicarb soda (baking soda) mixed with hot water, helps to neutralise the acid and corrosion. Make sure to give the area a good wash down with running water afterwards.

You will also need to remove the battery terminal and give them a good clean, both the terminals and battery posts.

[Dominator]

When you try to start it does it just click or does it turn over slowly?

[TJsGQ]

Hey..!
Thanks for everyone's advice so far..! So I have clean up the battery terminals n the leads to the battery was a bit of corrosion on it. And there was no difference in starting it.. Starts to try to turn over back takes a few seconds maybe 5 or 6 to get it running immediately on start up sits on about 600 rpm for a split second than goes up to about 1300 which is normal on start up than drops to about 900.. No ticking just turns over slowly.. Any more advice would be great thanks.!!!!!

With yendor.
You can pick up a battery terminal post cleaner for about $5 from most auto shops.
It has a bit for cleaning the posts, and a bit for cleaning the terminal part.
Alternatively, I have used a mild file to touch-them-up slightly.
Ensure the terminal is opened enough to push down properly and then tighten.
you can either get battery terminal protectant or I have used similar stuff to WD40 that doesn't evaporate

Checked the batt voltage as well and it 12.54V so it's all good there.. What am I lookin at maybe starter motor..???

[Parksy]

Have you given the solenoid a soft tap with a hammer before starting? These become dicky over time and a tap can be a quick fix to start the engine. Though this will need to be rectified if it is the cause to your issues.

As well as checking your battery connections, also check the wiring to the starter. There will be a thick cable that runs directly from the battery to the starter, maybe remove this connection from the starter and give it a clean.
Also inspect the cable for any broken strands, especially at the terminal ends. Too many broken strands and it will limit the current flow through the cable.

I assume that's when the car is not running......

Hey parksy yeh I'll give that a go tomorrow where abouts is the solenoid located..?? And yeh that voltage was with the car off..

[Parksy]

The solenoid is a small cylinder looking thing mounted on the starter.

[TJsGQ]

Hey so I have the solenoid a bit a tap before starting and there was a noticeable difference starting but still struggled a bit.. This time when it first started it sat at 600rpm for a second or two longer than before and raised to round 1300.. So with that noticeable difference I assume its my starter that's on it's way out..??????

[Parksy]

It does sound that way. Some starters you can replace just the solenoid, being the cheaper option. If you do this, and it doesn't solve your problem, then it could be the starter. Personally I would just replace the entire starter.

[TJsGQ]

Ok we'll that's the new plan.. Thanks for your advice..! How long till U think it will stop starting completely as it only started last week.. Should I be rushing out straight away n gettin one..?? And what's people's opinion the nissan genuine starter is in the 500 range but I've found one made in Japan with a 2 yr warranty for around 250??

[Parksy]

Hard to say how long it will last. I know people who tap the starter every morning and have done so for months. But then I can't guarantee this. Couldn't tell you about types of starters as I don't know. I'd probably go with the Japanese unit, being both Japanese made and cheaper.

[TJsGQ]

That's what I was thinkin been having a look around the net n forum n might have a go at rebuilding it and cleaning the internals out.. What's the worse that can happen gotta buy a new one.!! Any advice on that would be great..!

[Yendor]

It's a good chance your starter motor is full of mud.

Disconnect the battery, remove the starter motor, strip it down and inspect.

If it's not that bad you might get away with a clean out.

[TJsGQ]

I'm hopin so.. I read a bit about lack of. Current for the starter moter so may also try runnin an extra cable parallel to the existing one to see if that helps..! May even write up a new thread about it how to do it, can't seem to find one atm

[TJsGQ]

Ok so I've been doing some reading and I've read that if the motor is cranking that the starter motor is doing its job is that correct..? So if that's true it could be another thing causing my problem as the engine try and try's to start and than does start.!

[stayfresh]

hey ive got a swb patrol 88 tb42 that is having problems with the coil keeps on over heating and blowing up
and loosing power ayt the primary terminal but has negative and ositive feed onit

[david123]

check the battery and its terminals, read the voltage when it starts

check the power cable

check that your distributor is fixed, if it turns around with vibration, time is wasted

to check the start see if you can start the engine on a slope with the clutch

[Yeti's Beast]

Check the battery voltage while cranking the engine.
The battery May be failing under load causing the starter to turn slow and if it’s fuel injected it will not provide enough power to the Ecu and fuel pump as well.
As mentioned earlier. Try starting it with jumper leads and another battery.
