1984 Storm cutting out. PLEASE HELP

Post by eddymcbram »

So had the car a couple of months now and since owning the car, when starting for first time in the morning or if not been driven for a little while.
The car starts up straight away but th revs will immediately fall and the engine cuts out.
This can be remedied by touching the throttle to 'catch' the revs. Then all is fine. If you turn the engine off and restart it you don't even need to catch the revs, will start on the key.
Don't know if this is related to the issue i've been having the last few days but it may be a clue to someone who knows more than I do!

Anyway, so the other day went for a little drive, car ran ok, pulled over to roll a cigarette, leaving the car idling. After a minute or so the revs slowly died and the car cut out.
Left it a minute and restarted. Was ok and drove fine. Pulled over again and left idling. Took a while longer but same thing. Cut out.

So Monday a similar thing happened after pulling over. Only this time after restarting the car ran like shite and I had to pull over. Left for a minute or 2 and was ok for 6/7 miles. Drive home later was also fine but didn't stop.

Again today car cut out on me. This time wouldn't start for 5 mins or so. Today also noticed if left to idle, shortly before it dies I can hear a slight buzzing that increases before the engine cuts. Sounds like maybe fuel pump.

What I can't work out is why on earth it only happens at idle or low revs and not driving, and why it takes a little while for it to decide it's going to cut out.

Not a mechanic or anything, have no idea what it could be, help urgently needed please!

The car is a 1984 mk2 scirocco storm. Engine code DX

Thanks in advance, hope someone can help

My gut feeling says it's fuelling related. At higher revs the small amount of loss of fuel isn't noticeable but when at idle it is. This is also what it is intermittent. Check fuel filler neck at top for holes. Rusty bits may have fallen in the tank. Check the lift in the top of the fuel tank. Make sure the gauze is clear and tank looks rust free with no floating bits of crud in the tank. Replace fuel filter if not done recently. Not that much else goes wrong with inj engines! Not when it's a bit random.

If lift is blocked the fuel pump would be running with less fuel hence change in noise. Where does the buzz come from?

The filler neck I checked and is solid, has been replaced and treated. Am I right in thinking the lift is under the inspection panel under rear seat?
I thought the fuel pump was mounted externally? Sort of under/just behind the tank by the accumulater? Removed that yesterday and ran 12v to it, seemed to function ok. However this is also where I believe the buzzing sound is coming from, should it buzz or is that a sign it is on its last legs? :/

2 fuel pumps on later cars, I think your's should have a lift pump inside the fuel tank attached to the fuel gauge sender. Main fuel pump is the one under the car. The main metal fuel filter in the engine bay should be changed at least every 40,000 miles so worth changing that and see what colour or any bits come out of the input end of the fuel filter.

If the main fuel pump has got noiser than before the lift pump could of stopped working and making the main pump work harder to get the fuel out and it will kill your main pump quicker.

There is also a filter on then end of the lift pump so check that's clean and while it's out of the tank have a good look inside the fuel tank for dirt, grit and rust.

Thanks for the info on the pumps, will pull the lift out and check the tank while I'm in there. Do the fuel filter aswell.
Cheers for the link for the pump. Hopefully can solve it and it's nothing more major :-)
Supposed to be driving to hastings today, not going to risk hitting traffic and cutting out on dual carriageway :|
Always the train I guess :|

It's a bayonet type fitting, if it's the metal type you may need a thick metal bar (trolly jack handle or big thick screw drive) and on the raised edge/cut outs place the metal bar and gentile taps with a hammer, you only need to move it about 45 degrees and it should come out, watch out for the big rubber seal and keep it safe, a little grease applied to the seal will help when putting it back together (if you have graphite grease better but I just use a little smear of normal grease) If the seal leaks petrol will come out while driving.

It's a little tricky getting the pump and sender out as the arm of the gauge sender is at right angle to the pump but if you are careful it will all come out.
Check the little rubber hose which connects the lift pump to the sender as they can fall apart as they sit in petrol all day long and the extra stuff they put in petrol these days does seem to rot rubber hoses.

Right, got it out, I small amount of crud in the tank, fished out as much as possible with magnet stick, going to change fuel filter in engine bay.
Lift pump I tested direct to battery and does not operate.
My pump however looks very different to the one mark1gls linked. It's vw part 533 906 092. Rang local parts specialist, vw heritage etc. They say they can't even get the part special from Germany :(
Quite new to the forum but will try to attach picture.
- Picture is too large

Thanks Shane, may give you a ring when getting round to checking voltage etc.
Actually just got back home from ECP, needed some leads and plugs. They don't have the pump or the fuel filter. I actually worked there up until about a month ago! Guys in the office had a look for me, couldn't find the pump, rang a few specialists aswell etc. Couldn't find one. Fuel filter they referenced was way too big and would not fit.
Think I may have tracked one down, local company have it coming in tomorrow am. They weren't 100% if it was the right one but said if it's not I can just give it back so that's cool. They have the fuel filter aswell. Fingers crossed on the lift pump!

The is 2 types of fuel filter a big fat one and a thinner one, yours is the thinner type, I'll try and find you a link but eurocarparts and gsf used to sell them as they have sent me the tinner one before as I need the bigger one.
Early cars upto approx 1984 had the thinner filter and later cars had the fatter filter.
The lift pump I posted the link to should fit, yours may have a sort of bag filter on the end instead of the plastic disc type like in the link. If you replace the rubber hose between the pump and sender and make sure the pick up on the pump is at the same hight you should be fine. If you could post up a picture of the electrical connetor going to the pump we should be able to see if it will fit as that may be the only differance.
To post up pictures upload them to photobucket or simular site then copy and paste int IMG for the picture.

Just checked the vw part number you posted and it list the same pump for my DX engine mk1 golf cabriolet and I bought and fitted the same pump in the link so I'm 99% sure it will fit but if you have a photo I may be able to tell and be 100% sure as I don't want to be wasting your money.
