Hi All, BSI sleep mode, causes no sleep for 6 weeks.

[RocketRonMorris]

On a very sunny day about 6 weeks ago I decided to repair my partners 206cc HDI 2004. It had an injector blowing and was making the old girl sound like a Lister diesel engine, After a successful day the engine started up with no noise,
(pig of a job) But it's a nice feeling when all goes well, Ran the engine for about 15 minutes then turned her off to clear up my tools ready to give it a run out, It was about half an hour before I returned to drive the car, Got in as normal to start the engine, It would not start? an d it's never started since, and that was 6 weeks ago.
So the first thing I did was to check everything That I touched when doing the job, All looked good, So in comes the first expert with his Diagnostic equipment, The only fault showing was heater plug relay not showing, plus a second test showed that the injectors had no power going to them hence it not starting, he found this out by fitting a test lamp to the end of the cables going to one of the injectors, He left without solving the problem, In comes the second expert with his box, He could not find the fault and left, But on this last occasion after he had left I noticed when I tried to start the car the Eco-mode was showing on the dash, so now I decide to check what else is not working, No headlights, No wipers and washers, No radio, in fact the only things working were sidelights, electric windows, and central locking.
So now with more faults in comes the third expert, George came with his little box and can't find any faults other than what's showing, George said more time is needed get it towed to his garage and he will look deeper into it,
George decided that the BSI or ECU would need repairing, cut a long story short, I acquired a second hand BSI, ECU and ignition key and barrel, all the part numbers were the same, by this time with help from the internet the 3 minute rule had been found, and the new second hand parts were fitted, The battery was reconnected using the correct procedure, and hooray the eco-mode as gone replaced with a flashing date and temperature, Lights, wipers, are all working, So now is the important part will it start? No, it will not start, Now we're thinking we've solved the BSI fault but not the original fault of not starting (engine turns over fine and battery charged at times) So George decides to test the preheat fuse and forgets about the 3 minute rule, now we have eco-mode back, (soft re-boot) as been tried many times when eco-mode was showing on both systems,
So I'm now back to the start again with BSI in eco-mode and will not reset, and no power to the injectors stopping the engine from starting, I'm very close to scrapping the car and putting myself in the crusher with it. Who ever solves the problem will also save a life Ha! Ha!

Firstly, welcome to the forum.

Don't get too hung up on the eco mode. It will go when you eventually start it. It's a power saving mode (hence eco) that shuts down non vital systems after prolonged failed starts, which is why it's things like radio wipers etc that go to sleep. Lights aren't affected as they are a safety item.

There was probably nothing wrong with original BSI. It sounds like it might be an imobiliser problem. Firstly- did you remove any earth connections when you carried out the original work? Check those first. In fact check them anyway. Check for a voltage (ign on) between one of the injector plug pins and ground, then do the same for the other pin. What have you got?

[RocketRonMorris]

Thank you for your reply, Checking the injector plug for power, are you saying just with the (ign on) and not the engine turning over?
I will check in the morning and give you the answer, Thank you again.

[Capncol]

are you saying just with the (ign on) and not the engine turning over?
Yes

[RocketRonMorris]

Sorry about the delay, Now have the car back in the drive, With (ign-on) Both cable connection points for the injectors have no power.

[Capncol]

Hmm. Pointing toward immobiliser fault which may be something to do with new BSI / ecu. Have you still got the old ones?

[RocketRonMorris]

Hi, The fault of no power to the injectors was there the first time hence why it would not start, and when the BSI and ECU were changed the same fault of no power was still there stopping it starting, all we've done trying to find the starting fault is give both sets of BSI and ECU the fault of ECO-Mode

[Capncol]

Please see my 1st post.


#1
ECO mode is NOT a fault. It activates after 30mins with the key in acc positon if the engine hasn't started. Read pg 109 of your owners handbook.

#2 You haven't answered my Q about the earth connections..

[RocketRonMorris]

Sorry, I did read a post where you had talked about earth's making faults, and I started looking for them, I cleaned two of them behind the head lights, but then stopped looking for others thinking that if they are as good as the two I've cleaned then they should be okay, I did look at and clean the one on the engine, but I've not found the others, When I was working on the engine before the fault I did not touch any earth's near or around the top of the engine,
It's very odd that the engine did start after priming the fuel as I did fit a new fuel filter at the same time, and the engine ran for about 15 minutes with no problems, it was only half an hour after I'd turned the engine off that it would not start and as not since, and the fault is no power to the injectors,

[RocketRonMorris]

Hi Capncol, I've now found all the other 5 earth's and cleaned them, so found a total of 8, still not starting, I still have the original BSI, ECU, and ignition key with barrel, I've also got a spare under the bonnet fuse box. I've also checked the power supply to the injectors with the engine being turned over but still no power. The other fault that as been over looked is the preheat dashboard light, it doesn't come on, even for the short time it should when the ignition is first turned on, even in this temperature it should show for a short second.

[Capncol]

With no power to injectors, it's sounding more like an immobiliser fault.
Incidentally, how did you cure blowing injector? Replaced it? With new / used / refurb?
One last thing (and I don't normally advise using this) try some ether (easy start) and see if it will start on that, but it may not continue to run.
After that, I would put original BSI / ECU etc: back in and start diagnosing again. I think you were chasing red herrings with the eco mode. You may have faulty replacement BSI.

[RocketRonMorris]

Thank you for the reply, The blowing injector was the fault of the copper washer at the base of the injector, I made up my own cleaning tool to pre-pair the surface seat in the cylinder head and when the engine fired up and ran for the 15 minutes after the repair the injector had resealed and was running perfectly, The first engineer that came to see the car was an AA engineer I was lucky to know him, He tried the dreaded Easy start and there was no hint of the engine firing, I was concerned by the amount that was put in the engine, I will put the original units back on the car as I think your right about there not being anything wrong with them, I've made use of the ECO-MODE in the past when I've put the radio on when the ignition is of, When the radio stops and the eco-mode comes in I would restart the car to clear the eco-mode to use the radio again, But in this case eco-mode will not reset even after soft re-load.

[Capncol]

That's interesting. Have a look at where he squirted easystart as it's not unknown for people to take an inlet pipe off and squirt it the wrong way (towards the airfilter instead of the engine) If you get nothing with easystart, you may have a different problem completely such as a slipped cam belt. Does it sound *normal* when cranking?

[RocketRonMorris]

I remember him squirting it into the air cleaner the first time and getting nothing, so I removed the air cleaner housing and he tried squirting it start into the turbo, but again no response, I found it odd too because I know how it clatters if it fires up, I was even worried about if we did get it started would there be remnants of easy start still in the cylinders, Yes it does sound normal when cranking, There's no lack of compression, and no nasty sounds of valves hitting pistons, But I will check the cam belt.

[Capncol]

It only needs to slip 1 tooth to cause non start.
