I am having trouble starting the motor when cold.I have had the injectors cleaned & new glow plugs fitted. Once warmed up, starting is excellent.I have been reading the fuel system section of the workshop manual which mentions "cold start device".Any info on this item would be appreciated.

I've also got the 2.8 t.

I've just had all new injectors, all new glow plugs, and the small manual primer pump checked over.

I've just copied this from another forum, and it describes my problems to the nail. Starts dead easy any weather, but then after say 1 0r 2 minutes idling, starts faltering, then stops.

Real hard to start afterwards.

Here's the stuff I copied...

Hi can anyone suggest why my 2.8 n reg pajero cuts out first thing in the morning after 1-2 miles. It then starts with some difficulty but then runs fine all day. A mechanic has suggested it is the fuel pump drawing in air and that this will need to be taken off and sent to be refurbished at a cost of £6-700. If this is the case surely it would be cutting out continually, not just from cold. I have had a new cold start rely fitted it but still cuts out.

I too would like to get mine sorted out.

When we do get it started, it blows out clouds of smoke, we keep wondering when the CFS is going to arrive.

As my wife says...

It's economical alright, 'cause she gets me to take her to work, 'cause it won't start some mornings.

Thanks Neil & Margie.
I had an auto tech check out the relays & wiring, no problem apparently.
When I changed the glow plugs before, the problem disappeared for a short time. It looks like tike to change the plus again.

The Relay is mounted on mine,directly behind the Battery on the Batery Box,Also their is a large fuse to the right of the Battery Terminal just inside the Right guard.
Put a multimeter on the Glow Plug Bar and check Voltage to the glow plugs(you can buy Multi Meter form supacheap for $12.00. Listen at the same time while someone operated the glow plug with the ignition key.You will notice that the Power to the glow plugs is on a lot longer than the glow plug light is on at the dash.
I purchased new plugs and they only fixed the problem for about 2 weeks,I removed them and checked resistance accross each plug and they were all over the place. A mechanic then told me that many of the cheaper brands are rubbish and I then bought a Better Quality set and now everything is fine. However this does not fix your problem of after starting,cutting out.

Hi Trevor.
Thanks for the info. I have manual control for the glow plugs & will certainly retest them again.The motor does not cut out, only idles very rough at first. If I use the hand throttle to assist the problem is less obvious.
Perhaps I should go back to use genuine glow plugs instead of aftermarket ones.

I didnt go genuine ,first lot were from packets that had chinese writting over them, second lot were Bosch and are working fine (around $32.00 each) This fixed starting problem.
You mentioned running rough- mine is much the same
After starting it does idle a liitle rougher than time gone by
My thoughts are
1.fuel may not be as good as it use to be - I not sure.
2.My motor has 275,000 kms on it so there would be some worn bits.
3.I did up the idle revs just a tiny bit and it makes the car feel better.
4.I have had the fuel pump and injectors done up just having returned from the Canning ($800.00) and it didn't make a great differance to the rough idle. That s why I think the fuel is not being produced and burning as well. If do come up with a resollution I would like to know,but this post tells me that the Engines have a similar feel about them.
Hope this helps a little.

Similar problem with my Triton diesel.

As Trevor said above: "You will notice that the Power to the glow plugs is on a lot longer than the glow plug light is on at the dash."

I find if I leave it for an extra couple of seconds after the glow plug light goes out, it makes a difference. You can actually hear the switch click off (providing the kids aren't in the car).

Check ALL of your glow plugs. Just a couple being off spec can make cold starting difficult.

Next check you are getting the appropriate voltage at the glow plugs on cold start (some engines use voltages otehr than 12V)

Hi Dave.
I checked the volt reading to the plugs this morning.The reading is 11.3v.
I will rewire & measure again.
Thanks for your advice.

11.3v should be adequate when they are on.

Some manufacturers use a 6v glowplugs, with a dropping resister. Obvoiusly not on your car.

Next is to check each glowplug I guess, assuming there is adequate fuel when cranking form a period of inactivity. My step father had that problem, and it turned out to fuel syphonning out of the injector pump (due to dodgy non return valve).
