I have a 3.4 litre diesel landcruiser. I have fitted a brand new, best quality battery.
When I start I have to glow twice. I guess this could be a glow plug problem.
However, are there any other gremlins that could be causing the problem apart from the glow plugs? Thanks, Ian

I sold my my BJ70 3.4D back in 92. I did have a problem starting the BJ70 which was fixed by changing the glow plugs. I might be wrong but I think I probably caused the plus to fail by thinking that glowing the plugs more than once when in very cold location (Bluff Hut, Vic) would help it start. I think the BJ70 doesn't like glowing the plugs more than once before cranking it over. At least that my thinking. At least they are not to hard to replace yourself.

make sure you get the right glow plugs, toyota are notorious for different voltages for glow plugs in the same model.check glow plug relay, if not cutting power at right time the plugs will burn the tips.

Thanks Anthony. I think I'll start with some new Glow Plugs. The engine is generally in good condition I believe. Cheers

When my old 2h donk became difficult to start (especially in the frost) I suspected the problem to be associated with the glow plugs/circuit.
After quite a few dollars in plugs/diagnosis, low compression turned out to be the culprit.
New rings/bearings and a valve grind and she went like new again.
How many km's have logged?

Thanks Furph, My BJ70 is a beauty. I bought it a few months ago of a lady who had owned it for 17 years! It has 200,000 genuine k's on the clock. The oil is a clean as honey. So i think the little 3B it is in pretty good nick. Cheers Ian

Has the hard starting gradually got worse over time or was it fairly sudden?
I owned a BJ70 with a 3.4 litre motor for 8 years and I had several months of difficulty starting it cold towards the end. Went from starting first go everytime to not at all within a week.
No one wanted to look at it, said it was due to the high kilometres (over 430,000k) but compression turned out fine, glow plugs, battery etc, all fine and I finally found a diesel place that diagnosed the problem, a slightly loose wire near the alternator!
You might be lucky and find a similar simple fix but it took me months and a couple of cans of "Start ya bastard" before I got there.
If the deterioration has been gradual and you've done high k's then check the compression.

Thanks Tim - I've only had it for a few months. I think I will start with some new Glow plugs. The Toyota ones are a bit pricey ($35-40 each)but I guess I might go that way - at least there are only 4! Cheers Ian

Don`t buy cheap gloW plugs as I have bought off ebay (4 of for $30).
THey burnt out in 4 weeks and the guy said ? dunno ? and no refund.
Typical chinese junk..

Most auto shops have quality bosch or similar glowplugs which I bought around $80 for a set of 4, for hilux 2.8D.

Thanks, Yes I think some trustworthy plugs is the way to go. At least that way I can tick the plugs off as not being the cause, if the problem persists. If you know what I mean!! Cheers Ian

you can test them. put them on a twelve volt wire and see if they glow. they should glow red in a about 3 seconds. if not you should get new ones
