Ive got problems starting in a morning (all the usual things seem ok, such as glow plugs, air in fuel, and advance solenoid). Once running, the car runs ok, but smokes like hell, and has an intermittant miss fire. The final problem is that my fuel consumption has gone through the floor, I was getting about 40 mpg, now down to about 26mpg... Starting the car when warm it strikes up first turn. And all this since I went to see the dervdoctor. Before then, it was fine. I resent going all the way back to derby to get it sorted as its a fair distance to travel.

Has anyone any ideas? Other than not to trust the w***** as far as you can throw him (which aint all that far).

Car still drives ok, plenty of pull etc (although it doesnt seem all that much more powerfull) just the economy and the smoke is a sod.

I feel Ive been ripped off by £180 for some diesel injector cleaner and a few bits of blue rubber pipe - and the cheeky c*** sticks stickers all over the car for advertising... hopefully the amount of smoke it emmits will stop anyone reading the number.

For your reference, the job was done about a month ago.

Help please... im a poor student and its saping my bank account like money is going out of fashion.

I aint checked it, I wouldnt know how! I could check it if someone were kind enough to tell me how :stupid: . Other things to note, I serviced it about a week ago, new oil, air filter, oil filter and fuel filter + seals. And the smoke is Black / White (not blue) and it doesnt burn oil.

black and white sounds like advance solenoid to me.

Well if im correct in thinking, the advance solenoid is the thing that clicks a fair few times when you turn the key to the "on" position before starting. IF this is so, it clicks a fair few times (6 or more?)... Il have a look at the egr thingy later, but would this cause really really poor consumption?

funny thing with that, i thought it was that that made the clicks but ive discovered it dosent. i was trying to bypass the imobiliser by wirig the fuel shutoff valve at the back of the pump direct to the battery and when doing so it made the nesecary clicks loads of them as it usually does so im sure the advance solenoid isnt what actually clicks i even put my hand on top of it see if i could feel it but i couldnt but the advance solenoid must play some part in it somewhere, as the clicks tend to get less when its failing/failed.

my guess is when activating the shutoff valve it moves something on the end of the advance solenoid right deep in the pump.

Ok, well, the car is actually at the local diesel specialist at the moment, but he was as stumped as I was, so hes having a look over it and il know whats what later. When he was looking over the car he mentioned the advance solenoid "and it appears to be working.... its clicking" or something along those lines. So my impression was that its working, but then I guess it might not be. He also thought that the injectors could need overhauling as the cars done 120k and possibly aint had any new ones in it yet. The other thing he mentioned is that the fuel pump could be overfueling (due to the dervdoctor setting the fuelling to high), which would require him to take the pump off and recalibrate it (not an expense I would like to incurr). Il report back tonight when I get the car back, and il investigate the EGR valve, and the advance solenoid. Thanks for the quick replies

Well after all that it turns out ive been barking up the wrong tree. The local injection specialist has looked it over, my injectors are fine, the egr and the advance are fine. The problem doesnt lie with the derv doctor, only his adjustments have amplified the problem. It would also account for the "turbo being weak" as the derv doctor said. I feel I owe an appology to the derv doctor for slating him as it would apper that....
... The local garage that fitted the timing belts have fu**** it up. The pump belt has been fitted a tooth out, and then the pully has been fully adjusted to make the thing run something like. So, Its going back on monday to have the timing belt refitted properly. My only concern now is - once its actually timed up properly, It might go like stink, use a lot less fuel and not smoke!.
But, if the belt has already been fitted, is it wise to refit it or should the belt be replaced?

Well its even more Ill now... didnt want to start this morning, and when it did it was lumpy, really lumpy. It stopped and im having a great deal of difficulty keeping it running. Ive checked and theres fuel there etc. It ran for about 5 mins to defrost, then spluttered to a stop and is now very very reluctant to start... I hope it aint done anything bad. Im now wondering if one of the belts (eg the pump belt) has jumped a tooth or two...

i would get it looked at asap!

to be honest the belt might not have jumped because from what i remember with taking my pump off what i did was this:

removed timing belt cover (and anything else) and i undid the tensioner and then all i did was lever the pulley with like a crow bar thing. the pump isnt actually secured to the pulley :shocked: then behind the pulley was 3 torx bolts holding the pump onto the rear cambelt frame so it could be that the pulley has slipped? you might need a new one.

i was quite shocked at the design and im suprised that it hasnt caused as many problems. you would think not being secured and only the belt holding it on the timing could go out at any time :shocked:

Well after lots of jusddering and clattering it came to life. I added a fivers worth of diesel, taking the fuel gauge over quarter of a tank, (usually takes at least £15 for this) so I can guess that it wasnt out of fuel. Anyway it seems to be running ok now, just very smoky still. I havent a clue what was up with it. Its going in on monday to be checked out so hopefully all will be well again, unless we have the same troubles again tomorrow! It cant be air ingress as it started fine this afternoon after it had been stood all day, and id be doubtfull that the glow plugs are amiss as they have only been in a few months. Il let everyone know what happens, thanks so far for the advice ;)

Well its been to the garage... and the timing was fine... So someones feeding me bull. he adjusted it slightly to see if it would stop the thing smoking and help it start better on a cold morning. The smoke isnt as bad, but cold starting is still very very poor. Im at a loss. Ive been on the blower to the derv doctor who kept going on about me getting the injectors replaced (even though they are fine!!!) and he thinks that its nothing to do with what hes done to the car. Im getting really really wound up as the only solution I can see is take it to a diesel specialist and get the fuel pump calibrated properly (costing over £400) and having the turbo set back to the standard etc. The thing is im getting reluctant to spend much more as I could buy another mk2 diesel car for not much more and just stick all my ghia x bits in it. Just dont know what to do!
