Thank you Monkey, I am based in the Midlands, in between Wolverhampton and Stafford.  The garage I have used are a specialist but I have zero confidence in taking it back there.

New Members Say Hi! / Hi all / bringing back to life a 91 td
Last post by didigolftd -
Hi all, I picked up back my mk2 which was left for at least 10 years in the garden. I have this car since 2009 and stopped using it in 2013. Got it back to drive, I can let you imagine all the work to be done on it :'(

Its a 91 fire and ice SB. I'm in France

Could be the blue temp sender.
It lets the car know when it's cold, to enrich the fuel etc.
Next time, try unplugging it when you're having issues.
If it does turn out to be it, don't buy a cheap one, there's a lot of dodgy pattern ones floating about on ebay.

Engine & Gearbox / Rough cold starts
Last post by JacksonBrownPants -
Hey,

Got a digifant 8v. Car was fine but in the past couple months has started to struggle to start. Often it starts and it's super rough, sounding almost like it's cammed, sometimes it's even so lumpy that it cuts out. Once it cuts, it really struggles to start again. Once it is running and has had a few moments for the revs to settle, it runs perfectly fine, and once it's hot will start again no problem.

There's nothing obvious. I'm going to clean the ISV out and see if that helps (checked and it's definitely still working), but if it doesn't i'm not sure where to start looking next. If anybody's got any ideas, i'd love to hear them.


TIA!

Hi and welcome!

Ok, there are two things that I would check, first being the compression.
I've had a mk2 16v before where it would start and run, but once up to temp, the compression dropped and had no real power.
I'd also struggle to restart the car. Genuinely hope it's not that one, as there's no cheap fix for it.

Second (and more likely) thing is that metering head:
The mk2 golf 16v runs on K-Jet, a mechanical form of fuel injection.
Essentially, it relies on incoming air lifting a flap (under the big black boot, above the air filter) that increases the fuel pressure being supplied to the injectors. When it works, it works well, but it needs to be set up correctly and from the sounds of it, the car runs well when warming up, which is when the warm up regulator is pushing more fuel into the inlet, but when the car comes up to temp, it shuts off and drops the fuel, leaning out the mixture. You could detect this by going to a garage with an exhaust gas analyser (any MOT station) and asking them to measure what's going on when it's running rough, if it's lean, that's your problem.

Now the compression can be done quite easily by yourself, if you're happy tinkering and have a compression tester.
The fuelling should really be done by someone who knows how to do it and has an exhaust gas analyser.
You don't mention where abouts you are, if you let us know a location, someone nearby may know for a good garage.

I do really like those Chris Fix videos, shame he's slowed down producing them.

So how slow was the cranking getting?
As oil pressure builds up, you will notice it slow a little, also, your battery is probably starting to get tired (unless you're charging it between fault finding sessions).
One thing you didn't mention, did the oil light go out?
If it goes out, you've got good oil pressure again and can attempt a start.

Another thing you could try is to take out all four spark plugs, this will remove the resistance caused by the engines compression, it should spin pretty quickly then and get oil everywhere it needs to go.

I bought my first VW classic January this year, a mark 2 golf gti 16v, 1991, being around classics for over 30 years this one is proving particularly troublesome!
I had poor running problems a few months into ownership, would run rough, little or no acceleration after warm up.
Booked it into a specialist:
£1000 later, service, timing, gear box timing inspection bung, thermostat housing, fuel pump housing, lift pond in tank replaced.

The car runs exactly the same, runs perfect for the first 5 miles, as soon as its warmed up little or no acceleration.
I am really struggling to find a garage that either knows how to resolve this issue…..I really want to enjoy the car ion these simmer months :(
Any advice would be really appreciative

Would another idea be that maybe the system has drained completely while it was stood and when I turned it over fist time it siphoned out the last bit of oil from the system and caused an air block maybe?

Going to try and fill the oil filter up with oil and crank it without the dizzy king lead on to see if it gets it circulating.
Clutching at straws here 😫

Good to hear the engine is still spinning, fingers crossed, you may get away with it.
Must admit, I keep coming back every couple of days just to see how you're getting on!

Thinking about it, it might be that there was just an air lock around the oil pump and it didn't pick any up.
I wouldn't try and overfill the engine, just fill it up to full, pull the king lead and then turn it over for a minute.
The slower speed of the pump should pick the oil up and send it around everywhere, once you see the oil light go out, you know you have pressure. Give it a minute or two and look at the oil level again (you may need a small amount more), then replace the lead and attempt a restart.
