Fair point I can see stopping distance at 30/40 mph on the road in front, what i can't see is stuff looming in the hedgerows and at 7 foot above the road surface which is the issue.

 

Seriously though who is responsible for cutting back the growth from the road side? The land owner or highways? In a couple of points it's that overgrown that you are forced to use the centre of the road on blind bends, obviously this slows traffic to stopping speed unless it's an Audi.

I've been onto highways who didn't seem interested tbh.

 

The landowner I think, but that's just going on hearing of people getting done for their hedge blocking paths.

With roadside hedges there is a bit of a grey area in that the landowners used to cut them up until they were told they would have to use white diesel in their tractors to do the job. Obviously they got the hump and stopped doing it leaving it in the safe hands of the local authority. Which is why you are lucky if the hedges get cut at all now. Most farmers do like to keep the hedges tidy but due to the additional bureaucracy placed on the job they tend to not do it anymore. I went to a farm sale many years ago and overheard 2 old boys talking about a snow plough that was in the sale. They both agreed that it was a daft idea to own one as you could get in so much grief if you did use it on the road that it was better just not to bother.

Can a slightly soft tyres trigger a false warning re: ABS, TC & ESP faults? Did my weekly tyre pressure check earlier this week using a different airline from the one I normally go to, and since then the ABS etc on the Saab warnings have buggered off, whereas using my 'regular' inflator they stayed on.

 

Just makes you think if petrol station tyre inflators aren't particularly great. I used the calibrated one at work in the workshop instead this week

OK, this Buick is starting to get on me tits.

 

It FTP'd just over a week ago now and has not run since.  Last weekend I ascertained that it was sparking OK, as it fired up on Easystart, so a fuelling issue was suspected.  Unfortunately I ran out of both daylight and feeling in my hands before I could investigate any further.

 

Been out there today and took the fuel inlet hose off the fuel rail, intending to blow through it with a compressor to clear any blockages.  Thought I'd just check how blocked it was, turned on the ignition and a veritable geyser of petrol spewed forth.  It stopped after "priming", but started again as soon as the engine was cranked over.  So it's definitely not a fuel blockage.

 

So it's got fuel, sparks and compression, so it should start, right?  But it isn't even trying to start.  My only conclusion so far is that the injectors must not be firing - but I'm not sure what triggers them.  If it was a knackered crank sensor or whatever, then presumably that would stop the ignition from sparking as well?  I pulled the plug off one of the injectors and stuck my multimeter in - it was showing about 8.5v with the ignition on, but I have no idea if that's normal or not - I basically have very little idea how EFI actually works. 

 

Any suggestions before I drop a match in the tank?

Has anyone on here had a Mercedes W202 c200 of around 1995 vintage?

If so, give a review if you wouldn't mind.

Seen one for sale that's quite taken my fancy.

It's an auto naturally, so was this in the days before the problematic solenoid plate autobox?

Ta in advance.

I had a '96 one, these had the reliable 4-speed 'box and proper paint; facelift models from around 97 had the 5-speed box and water-based paint.  Failing cats was a thing (it would break up and rattle), mine inexplicably popped a head gasket too, but apart from that it was a very nice thing.  Not fast but smooth and composed.  Obviously check for rust.

Have you had the plugs out? My old sigma refused to start one morning after running fine. A quick check showed almost 2mm gap on the plugs..

I had an auto, slow as fuck, Rusty as fuck but a lovely old barge none the less. Suspension killed it in the end as they use a lot of bushes which I think must be made by gold clad Tibetan virgins judging by the prices Merc were asking. Iirc a full set of bushes was about £300 a side or something stupid and they are a bastard to fit. I also had a snapped injector, but that was more down to the dickhead who had it before me than the car itself.

I’ve wired in a usb charger/cig lighter/voltmeter/switch panel to my van and it’s running off an old mobility scooter battery.

 

The battery also runs led lights in the van with no problem, and it fires up the voltmeter and the cigarette lighter. I ran a little compressor off the cigarette lighter to check. It won’t make any usb chargers work though, and the light on the socket doesn’t come on at all.

 

Would the USB port sockets take more power just to illuminate the light that shows they’re getting power?

The battery is old and well past it’s best, but seems to do everything else ok.

I'd assume so. Enough of a difference in rolling radius between two wheels could cause a fault condition as it thinks one wheel is running slow. I've never seen it happen though so I might be talking crap.

I haven't, as they're smoll plugs and I've broken my smoll plug spanner.  If it was plugs though, would that not also have prevented it firing up on Easystart?

I can certainly have a crack at the plugs - they don't look in the first flush of youth from the bits that I can see.  I just think it's odd that the car would go from being on the button and running perfectly well, to not even trying to start, with nothing in between.  I wouldn't have expected all six plugs to let go at the same time with no warning.

I'll clutch at any straw at the moment tbh.  I've been Googling the symptoms and the most common diagnosis is that the ECU has shat itself.  If that's happened then the car is scrap, sadly, as with all the other issues it has it's just not worth spending large amounts of money on.

OK, next question.  When I tested the injectors for power, I ran the multimeter from the positive to the earth wires on the connector plug.  This gave me a steady reading of about 8.5v.  However I've been watching some YouTube diagnostic type vids, and it looks like the earth wire is normally switched by the ECU to tell the injector to pulse - in other words, the circuit should only be complete when the injector is firing, so I shouldn't have got a reading on the multimeter when the engine wasn't being cranked.

 

Is that another pointer towards a failed ECU, or have I completely missed the point?

I'm not sure you can tell a lot from injectors with just a multimeter, the last time I messed about with this stuff I borrowed an oscilloscope from work because they switch a bit fast.

 

Have you tried taking the injectors out?  It's something they say to do when you check the spray pattern but you can cunningly see if there's any fuel at all coming through.

Haven't had the injectors out yet - the idea scares me slightly...

 

Agree that there's no way a multimeter will react quickly enough to detect injector pulses.  One of the videos I watched had the mechanic testing for injector pulse with a test light - given that they only fire every second revolution, when the engine is being cranked over on the starter the pulses are far enough apart to be picked up by the light.  I haven't seen my test light for years, so I will go out and purchase one.

That's exactly what the sigma did though.

 

Does the Buick have a distributor cap to dry out and spray with moisture repellent?

Is there any way to insure a car for a couple weeks that doesn't cost a fortune? Esure want £200 to insure a 530d until the end of the month while I see if it sells. Given it's a spares or repair and the now swapped policy was £300 for a year they can FRO. It's still tested and drivable so being insured helps demo it.

If i disconnect the battery on my 52 Honda  HRV  .. will the EML be cancelled ?

 

I pulled a connector off of the engine whilst it was running ,and it faltered, so I quickly pushed it back on..Now the EML is on.  :mad:  It's been on for a week ,I was hoping it would just forget.....

 

Funnily enough though , the car goes much better and pulls like a train at low revs :-D !! It's a V-tec , and normally it only picks up its skirts at 3000rpm onwards

Yes

 

Insure with admiral or elephant. Pay upfront and then cancel within 2 week cooling off period. Total cost for two weeks £25.

 

Done it a few times.

 

Normally use credit card as it is refunded before bill is due.

Yes, but hopefully it hasn't been stored in the ECU as an error - I can't see it doing that if it can't see the fault, unless the unplugging damaged the sensor somehow.

 

Unplugging it would register a fault as it couldn't see the sensor.

 

Get a cheap dongle & clear the code, I think mine was under a fiver & uses a free app on my phone.
