Hi Mike ...

we should have gloplugsdirect.com online very soon - selling blue-print glow plugs ...

They should come in around £70.00 for a set of 4

Simon.

Have fitted recommended replacement glowplugs ADT31811 (# on plug CP22 11v 4A) but they are not ceramic like the orginals, The engine takes 7-8 revs to start when cold which does not seem right, OK when hot 1-2 revs, pulling 60 amps on current meter at all times, preheat and post heat times per the book, Any thoughs on were to look ? engine only done 40,000 miles. and runs and ticks over perfect, am I being too fussy, although I am thinking of what will it be like frosty winter mornings.
Sure it is something simple needing adjusting but what ?

Hi Mike, what type of oil have you got in the engine and is it overfull?

Been down that route have 10-40 semi synthetic, I thought my oil might be too thick but is as per manual, I am wondering if the fuel is running back overnight as it seems to want to prime the system first, giveing thought to fitting a none return valve on the system between tank and filter or filter and pump but have no experience, as I have not found anything on the system you can adjust, maybe one of the vacum control valve diaphrams or rubber pipes need changing ? but which one as I have no idea what they control. and all the pipework looks like brand new.
Or is this the best you can get with the glowplugs fitted,

mine's a 1kz-t as well. It takes about 3 - 4 turns to get going which I find starnge also. Some of the Paj's I tested started immediately and they had been sitting in a garage for days or weeks.

I was thinking of changing the glow plugs too.

TBH, I am new to diesels after owning and doing a lot of work on a 2.2 Honda Prelude.

the only problem I ever had with slow starts on that was overfilling with oil.

Maybe it's just a 'feature'.

This forum is very quiet! Pity there aren't some serious Toyota Diesel heads around. Maybe we'll have to do all the donkey work for those that follow in our footsteps.

Good luck.

I am also new to diesels, but at the end of the day all motors are just a bag of bolts and work basically on the same priciple, do not think the slow start has anything to do with glow plugs now, older diesel engines did not have them anyway, thinking of a friends old David Brown tractor, you just made the mixture richer. Am going to test the assumption that the fuel system is primeing it`s self on the first few revs because the fuel is running back into the tank over night (knacker non return valve ???), going to disconnect fuel pump supply and connect gravity fed feed to the pump and leave overnight. Basically hang a independant bottled supply of fuel off the open bonnet, this may give a clue, all a diesel engine needs to start is fuel and compression and I have plenty of the latter, no dodgy electrics to cloud the issue, at least that is the theory as I do not want to go down the road of checking compression, not as simple as a petrol engine, keeping fingers crossed

The main reason I am on this mission is my lad has a knackered old Discovery (150,000 miles) and it starts with one rev, a big cloud of black smoke in reply but it starts, I bought this Toyota to show him what a proper 4*4 is to drive but he says nothing just grins and walks off, what a wind up. maybe Toyota should start makeing cars that give out black smoke at least they start.

PS agree with you not much going on on this site, maybe no one else has any problems ?

I work as a cab driver and on the old cabs with the rover engines if the cam belt snapped,and then not replaced tooth for tooth the timing would be out and it would be a b stard to start have you had your belt replaced and not refitted correctly ,its a very very long shot but this could be the cause.
mine is a 3.0 and the starter must turn once and then it starts.

Have now solved the problem by fitting a none return valve between filter and pump, (£4.50 - 10 mins to fit) Fuel must of been running back to tank overnight, the problem only occured after a long standing period i.e. over 12 hours, the simplist solutions are often the last you think about

[k1elliott]

Cool. My slow starting was caused by a cheap battery that was 50 amps short on power.
