Good day
I have an Colorado 3l turbo diesel. The vehicle is a year 2000 model. We are currently driving to UK from SA. We shipped the car from the UK to Durban. We are in Botswana now. The car is fitted with a safari snorkel. The problem I have is the first start in the morning. The car struggle to start. I had a Toyota air filter. I replaced the filter with an after market. It worked immediately but after a few days I had the same problem. I do travel on dusty roads. I do clean the filter at night with a compressor. It feels like the car struggle more when it rains. The glow plugs has been replaced 5 000 miles ago. I don't think it is the glow plugs. Any suggestions what to do? When i use the quick start it works.
Hope you can help.

karel
so it has the 1kz-te engine with/without an intercooler?
i have a trouble shooting guide for my vehicle, 4runner, that came with the
1kz-t (non-ecu, non-intercooler) engine. the link is here:

julian might have plenty else to add but i'd start with the easy stuff by
checking the electrics:
checking all connections (inc engine earth)
checking the battery (dead cells etc)
starter relay
what about your fuel filter? injectors? if you don't get a specific answer
from jv - download the bits of the pdf that might be relevant and work
through those.
because i had so many problems starting my truck i always try to park it
where i can bump start it easily!

Hi Karel,
It sounds like the fuel may be flowing back into the tank overnight because air is
getting into the fuel lines.
To confirm this, before you start in the morning, use the primer pump on the top
of the fuel filter to pressurise the fuel system - if I am right it should start
fine.
If I am right the two most common places where air gets in is either around the
fuel filter and associated pipes because they haven't been tightened properly.
Secondly also check the fuel lines back to the tank - I seem to recall issues with
the metal fuel lines near the tank rusting and pin holes appearing allowing air
in. Typically you will see a damp patch around any hole or loose connection in
the fuel line - if it on a joint, try to tighten up the joint, possibly adding a
jubilee clip if there is just the standard Toyota spring clip. If you have a pin
hole in the pipe due to rust, use a wire brush to clean off all the rust, ideally
getting back to bare metal and then use something like Liquid Metal or similar
sealant to seal the holes.
Ideally you should try to clear any of the rust off the pipes and treat with an
anti-rust treatment (like Kurust) before applying the sealant and then spray the
whole lot with a protective layer of Hammerite or similar paint, however I guess
you won't have access to that where you are!

Yeah Julian and co sounds like they have the right answer, fuel draining out
overnight.
I have seen this twice now, once with an LJ70 and once with my KZJ70,
although its a 90 series, I would imagine the same applies.
The symptoms can be different depending which fuel lines are leaking.
If it's the main fuel pipe feed then you will experience starting issues in
the morning, my bet is with corrosion on the pipes that go into the tank.
See if you can get your hand on top of the tank(look by the rear back wheel,
you may see the tank and a diesel stain if you are lucky) and feel for the
pipes where they enter into the tank, smell your hand, diesel smell? Pipes
are leaking and need replacing, liquid metal may work providing you gain
access to that place, I could not see above the tank on mine so had to drop
the tank and once I saw the pipes, it was obviously the problem.
It was 20-30 quid from Toyota for the fuel pipes that are inserted into the
tank. It's not such as bad job to do as it sounds, you have to drop the tank
and probably drain most of the diesel out, couple of hours work....
The return pipe seems to produce a different set of symptoms, being you will
be fine most of the time but then suddenly your vehicle may struggle to
rev(usually after revving quite hard or some hills and bumps) as air get's
sucks up the return pipe and fed into the injectors, producing an un-burnt
diesel smoke, although it still could produce bad start in the morning or
after its left to drain...
A quick test for the return pipe is to remove the pipe from the Injector's
side (where excess fuel flows back to the tank, not the one that goes into
the fuel filter) and stick another pipe onto it and plonk it in a jar of
diesel overnight and try and start in the morning. No problem? Then it's the
return pipe...my bet will be on the fuel pipes entering the tank...
Have a good look at where the pipes enter the fuel tank.
Hope it helps and let us know how it goes...
Martin.

Karen,
Despite the bad starting, stop using the easy-start. This stuff is
solvent based and has an effect on the valve seals, over time you need it
more and more until you can't do without it. I favour the fuel line leak
idea.
