A lot of 4cyl toyota diesels used glowplugs for starting, then there was a slightly reduced voltage suplied to the glowplugs. This was controled by a coolant temp sensor, when the motor was warm the voltage was disconected. This feature was to keep the motor running smoothly. This may be where the fault lies. Or it may have one or two
blown glowplugs, usualy indicated by running rough & missing on the affected cylinders untill warm.

This is probably a stupid question, considering that you've had the Vehicle for a while now. Are you waiting for the Glow-plug to go out before you turn the key to start the motor ? I don't know if this would make a difference or not.
Cheers,
Sheba.

I have a problem with my injected diesel Hiace stalling after starting on a cold motor. I can get around it by revving hard and seems fine once I move and motor warms up. There is a problem there but only on a cold motor and has only happened the last few days.
The question is could it be injectors and need a specialised diesel mechanic or should the normal servicing mechanic do. Appreciate any advice.

Thanks so much everyone, this sounds very familiar, running very rough and missing until warm DeBe. I take it a normal mechanic can look into the glowplug, rather than the need for a diesel specialist, can they???. I gave the glow plug a caning when my battery was low by using it twice before kicking over the engine, so maybe I killed it.
Sheba, I do wait for the glowplug but when I first got the vehicle I didn't have a clue about waiting and wondered why it didn't want to start.
Thanks everyone you have been very helpful.

After working for toyota for 23 years I would suggest the last few morning have been a little cool?
No one ever has glow plug problems until the cool morning start.
Diesels are compression ignnition.....fuel, air, heat compressed causes ignition (no spark plugs)
Take away heat and you get hard to start and rough running until the motor gets a little warmth into it.
I hope this helps

Hi Jeti
Firstly as a mechanic I would concur that it may be the glow plugs, your description sounds like the tell tale signs that would indicate that glow plugs could be at fault, However, it could also be the timer relay which controls how long the glow plugs remain under current. The relay has a set of contacts in it, as they get hotter the contacts separate and then the current to the glow plugs is disconnected, so, if they aren't staying hot for long enough, then you get the symptoms you describe. It is VERY unusual to have all glow plugs fail at once, unless the relay is sticking on, a complete reverse of it not staying on long enough, you would experience a very quick vehicle for a period of time and then it would settle down to normal once the glow plugs turned off. eventually they will burn out and then you'll have the symptoms you have now.
My advice............. A Diesel mechanic who can test the relay and glow plugs, not a normal mechanic who probably wouldn't know where to start and waste your money.
Hope this helps a bit.

It's a 2005 with 70,000 klms only and well out of warranty. A turbo charged 2.5litre without the intercooler.
I was the one who used the expression a normal mechanic meaning not a diesel speciallst.
Thank you all for taking the time to post and advise.

I phoned my mechanic who cant look at the vehicle until next week and asked if he can check the glowplugs and relay and no he says needs to go to an autoelectician.
The plot thickens a mechanic, autoelectrician or diesel specialist and I'm getting more confused now.

thank you so much for the offer, I'm in Western Sydney but don't expect anyone to do that, I'm happy to pay someone but confused as to who I pay to diagnose the problem. The Hiace has done 70,000 klms and I don't expect to be having problems with a low mileage Toyota so a bit annoyed.
thanks again.

Hi Sol
I didn't actually start the utilisation of the expression "Normal mechanic" I merely continued to use it as a reference point for Jetj. BUT, I take on board your own technical ability and apologies if the reference was offensive, certainly not the intention at all. As for describing normal, well as I'm sure you will agree, that'd be VERY difficult Over the years I have come across many a "mechanic" that was great with the old "suck-squeeze-bang-blow" theory, but couldn't get their heads around compression ignition, glow plugs, timer relays etc, etc, etc................. Anyway, what a great offer you made to look at it free of charge, good on you for that. Hopefully we'll be able to compare some notes around the forum in time to come. Best regards

Hi jetj, are you with the NRMA, and if so are they like the RAC and give their members a free diagnostic inspection? I am with the RAC (in WA) and recently I had a problem that need a diagnostic tool (engine light was showing a fault) and they diagnosed it and reset it, was only a malfunction. This was free. My Transit is a diesel and has glow plugs too.

Vic,
I did get the NRMA out the first time it failed to start and he told me to take it to my mechanic. They don't do diagnostics here. When I bought a new battery they wouldn't even help me connect it because they sell batteries.
Duh said
05:40 AM Jun 20, 2013
Sounds a bit rough Jannete, maybe the RAC does more than the NRMA, they sell batteries too but will help you whatever battery you have in.
The RAC has road service, but you also have the option of booking your car in for a free diagnostic check at one of their depots if you think you have a problem. They even provide a drop off and pick up time for you within a certain distance of the depot.
