Ok I put this in bullet points, to keep it simple. Ive just got back into the scene after a long time gone.
* recently aquired 93 3.0td 1kzte auto, Stock form. Got it cheap, knowing it had some problems.
* it had a known hard starting problem, perticuly when cold.
* Ive replaced the old fuel filter & fixed vacuum in tank, causing pressure loss at filter pump. Primer pump, isnt rock hard, but only take 1-2 pumps to get real hard & holds it for as long as ive been able to wait.
* Ive bench tested the glow plugs, they heat up ok, Red hot. & cleaned teminals etc when reinstalling. there getting power etc,
* Air filter doesnt look too old. & ive given it an oil change.
* injection pump Has been refurbished or had some work of motor prior to my time. probably at same time cambelt was done. about 30k ago.
* surf is a high mileage one, ( 260k)
*Has a aftermarket glow plug timer of some type. so always does a long glow ( 5-6 sec) before light goes out & starts flashing ( 3-4 times).
* has New Batteries (pair)
* Have no check engine lights occuring ( yes bulb is still ok)
Problems
* starts better when cold now, but still takes 2-3 full cranks. starter motor sound fine. Get a litte lite couloured smoke ,but not as bad as before. sometimes runs rough for a little bit, unless idle up switch used
* is actualy harder to start when warm. takes a fair few cranks (6-10) at least. but starts better if I push accelorator down to the floor. Sometimes get some black smoke with this, sometimes not.
* Has good torque up till 2200 rpm, but has bugger all power after that. It seems unwilling, & doesnt apear that it would rev past 3000 rpm much, if at all. It still blows clean, theres no visibal smoke when looking behind.
* At about 2200 -2500 rpm, i can hear a whislte come on( turbo i guess) But get no increase in power or revs, & still no smoke.
* not geting very good fuel ecconomy at all. I dont drive it hard, tyre presures are fine. have replaced rear lsd diff.
* Seems to get up to normal temp, very quickly, faster than any other diesel ive had, but does not overheat. I do have some coolant loss via a weeping top tank on the radiator, which you will be familia with.
* considering all these problems & age of the surf, It still ticks over well, pulls well up to about 60kms, usng the torque. doesnt blow any smoke of note, apart from start up. But Ive been in a few of these, & it should go better.
So im wondering if anyone can decript all this & offer some more idea's. Im thinking about getting the injectors rebuilt, but not sure if thats actually the problem, due to the lack of smoke. Ive not been able to find any vacuum or air/fuel leaks either. Im hoping to have a boost guage hooked up soon too.
look forward to your replies.
