Sorry Kevin, yes, i did mean open circuit


Right, when i disconnect the ECU, Injector one + side returns to normal (open circuit)

[Marks DTM Calib]

So the output is shorted in the ECU.....

Thanks Mark, yes it looks that way,   at least i know what's wrong now.

Do you think its possible to repair this on the circuit board, would this be like a resistor, solder joint or would it most likely be a chip in there.

I think i might have to send the unit away for repair, do you think that would be the best way to fix it as i will keep the codes etc on my unit.

Its likely to be a chip.

Most commercial injector drivers drive the injector with an initial high current to get them to open followed by a weaker hold current. Doing this minimises the back EMF and also speeds the close time up and hence they can be quite a complex IC.

If you get the thing repaired then phone round for a quote first.

I have used the lower one before.

If going down the second hand route then you would need the immobiliser chips from the keys, the immobiliser ECU and the engine ECU.

I used BBA Reman for an ABS ECU repair, found them to give excellent service.

It is worth giving them a ring on 01634 230 055 first as when I did that they explained every little detail of their procedures to me, left me in no doubt as to what they did, how they did it, what the warranty was, costs, delivery .. everything.

And then they did the job exactly as advertised...  

I certainly rate them highly

I have decided to send of my ECU to a company called ECUtesting.com based in Nottingham to be honest they were the first people i called who quoted me 100.00 + vat for a rebuild of my ECU, I then phoned a store not that far from me who laughed and said he would not do it for that, thought i was having him on so i will see if they deliver the goods, so far they have been very professional and competent.

To be honest when i looked at the BBA website i thought they were in the business of selling new ECUs so i started looking around.

I will let you know the outcome... thanks everyone, especially Kevin and Mark for staying with me on this.

Cheers
Steve

Right........................

Got the ECU back today from ECU Testing . com and it has resolved the problem with the injector malfunction, EML is no more..... but before i write a success story i do have a new problem which at first glance seems quite serious but i need to look into it further.

Basically, engine is running on all 4 now and ticking over nicely, when i went out for a spin i noticed a minor lack in power when the car gets to around 50 mph, then a major lack of power followed by a load of thick (i think it was blueish) smoke from the rear exhaust which returns to normal when power is reduced and car is driven at low speeds ?

Im off to borrow a compression test to check that but im worried there may be some issues with the oil rings but im not concluding that just yet.

Its a shame because i have done a lot of work in one go which doesnt help, i now have a second hand cylinder head which i dont know the history of and perhaps (although i checked all the valves) might be causing some issues.

[Marks DTM Calib]

Thats the outfit I have used before and they are very good generally.

As for the smoke, do check the obvious.....i.e. airfilter, fuel filter etc.

Almost There.......

Right, the smoke was mainly down to having too much oil in the engine, i removed to the max level (about a litre) and that seems to have stopped.

As for the lack of power, well, losing the excess oil has helped but it has identified that I'm not losing compression or electrical power but i seem to be losing fuel feed, just going to get a fuel filter and start from there.

It is running ok but if you put your foot down lets say on a nice long straight you can keep your foot down and the engine will stop revving for a about 3/4 secs and then carry on, and then repeat, asif its running out of fuel and then not, its not that noticeable at low speeds.

I would not be surprised if the filter is partially blocked, with this problem i have ran the tank empty 4/5 times and a month ago it had two treatments of Redex.

Will report back..

PS: The ECU repair place is not far from you Mark, it cost me £129.00 for a rebuild of my own ECU, but i did have a few administration issues , first of all i called to see if they had received my ECU and the quote i was originally given was upped to 180+vat which i took as maybe i had not heard them right in the first place, but when it came to paying it was in fact £108+£8 shipping+vat and for some reason they forgot to dispatch my ECU and that caused 2 days delay but apart from all that i was happy with the service especially the price and it has a 2 year warranty and the main thing is they have actually repaired it.

Classic blocked fuel filter symptoms!

[Omega Steve]

Indeed, but not the case for me (asif i would get an easy problem)lol, replaced fuel filter, no change, however, when i turn the key to ignition i can no longer hear the fuel pump priming ? ? or at least that's what i think i used to hear, sounded like it came from drivers side, underneath, but on the other hand if the pump was not working would the car even run ? Its fine running around town, occasionally stalling at junctions, but take it on the (/) and as soon as you put your foot down the car acts up, reduce the revs it seems better and you can build up speed fine (just not in a hurry) lol

[Kevin Wood]

Could be that the fuel pump is on its' way out.

One way you can test it is to remove the return line back to the tank, extend this with a bit of fuel line into a suitable container and run the engine at idle whilst checking the flow rate. At a guess, you should see around 3 litres per minute or more out of the return line.

If that appears OK I would suspect a faulty fuel pressure regulator or blocked injector(s).

Alternatively, could be an air leak in the induction system causing air to enter the system without passing the MAF.

Don't suppose the air filter is clogged?

Cheers Kevin, ive got it working now.....

Right here is the deal, when i put the ECU back in i went to the nearest petrol station (also where i got the jerry cans worth from) and stuck a score in, this is also when i realised i had this fuel starvation problem, anyway to cut a long story short i ran that down to red troubleshooting this new problem, went to Sainsburys and stuck 40 quid in (half a tank) give or take and when i got to a (/) road i opened her up and the problem has now gone, so i can only conclude....

A) The petrol from the nearest garage is tainted or
B) The problem will re occur when the fuel gets to around quarter tank meaning i have a problem with the fuel pick-up.

Im more incline to go with option A but time will tell.

Car is now running like it should except on idle its jumping up and down a bit (it was doing this before my saga began) so ICV off tomorrow for a good clean.

Guys, thanks very much will all your help and suggestions though out my ordeal.  

[Kevin Wood]

Sounds like you're almost there

Could be that the pump is struggling on a low tank, or that it hadn't primed properly, or indeed that it was bad fuel, or there was rubbish in the bottom of the tank that got stirred up. Either way, a few things to go on if it recurrs.
