t25 coughing, spluttering and bucking intermittent fault!

Post by dubwright »

Does anyone know if my intermittent fault could be down to a faulty fuel pump? There seems to be no common denominator, just getting worse. Can happen when cold, or hot... Coughing, spluttering and bucking (and cutting out at low revs) mechanic doesn't think its electric as its all been changed, I feel its a fuel thing too... It can go for a while and be fine, then it happens, I can switch it off and sit a while, then it will run fine, other times it wont start at all. Brickwerks don't have a replacement pump for it either! seen some new on ebay for £34, http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0915406084" onclick="window.open(this.href);return false; but not sure if they will be okay, has anyone used one of these? Cheers! :D

Also what carburettor do you have and have you checked to see if your fuel filter is blocked with crud? That will cause these symptoms.

hello there -
make of carb usually stamped on top / side of carb - might have to clean up accumulated muck to see it -
fuel filter always worth a check - (as above) - lives under van - connected by a short fuel pipe to bottom of petrol tank -
condition - cloudy? dirty? water in fuel? v. easy to change - and would eliminate one possible cause -

useful to have your van details under your signature - avoids people having to keep asking -

stay with it! i'm sure more comments will come through - and lots in the wiki re: stalling/spluttering/ -

Check the cone filter in the inlet side of the carb IF it's a Pierburg.

Hi, me again, My 1985 T25 (1900 petrol DG engine 28k miles) still has the most annoying fault, it is getting worse and cannot be trusted to drive anywhere now...
It runs well, picks up speed well can run fine for a day or so but then all of a sudden, loss of power, misfire, backfire, cutting out, then it may correct itself. Or I stop for a few minutes and it then runs okay. But just as easily, it may not start for a few days!! :roll:
Such a random fault its hard to say what it is, no common denominator. Happens hot and cold, short or long distance.

Changed plugs, leads, distributor cap, fuel line, fuel filters, fuel pump...cleaned carb.

Mechanic now suggesting a new distributor, he isn't keen on me spending more money but we don't know what else to try, has anyone experienced this? any ideas? help!! :cry:

thanks to all that replied! I think we are okay now. After changing the plugs, leads, dizzy cap and rotar arm, ignition amplifier, fuel pump, all filters, cleaned the carb, replaced fuel lines... I think maybe it was a combo fault. It could be that the line into the fuel tank doesn't reach the bottom of the tank so I am keeping her topped up until the mechanic can sort that, he is going on a much deserved holiday after near going bald trying to sort the camper! :ok

There is no 'line into the tank' it is a metal outlet (and inlet opposite) that's a part of the tank itself. If that's really what he said your mechanic really DOES need a lie down ... under someone else's van :twisted:

Hi Deb, I had the same problem as you when I got my T25 in 2002. It used to splutter to a standstill several times on a journey and we began to dread taking it anywhere. I was told by a T25 owner that the petrol tanks on these vans are very shallow and when the fuel level drops below a quarter and slops around in the tank or if you are going uphill, the pump sucks in air and gives you the symptoms of running out of juice and the engine just stops running. Knowing this, (priceless knowledge to me) I will never let the needle get too close to the quarter mark on the gauge before I top up. I've had no problems since. :)

Well done Toby!Now that makes a lot of sense - I,too, have had a new fuel pump and filter, carb cleaned, fuel lines checked etc and still the engine would stutter. I looked back on the occasions that it has happened and it did seem to be when I had less that half a tank of fuel. It also seemed to happen after I had been doing about 1.5hours of motorway driving at around 60/65 mph. Hills and over-taking often were a factor - i.e. when the engine was under load (fast lane a definite no-go area!!). Sadly, however, I have now experienced it on a near-full tank also, so am still not clear of the problem!! (1990 1.9 water-cooled)

Could this be caused by a sticky choke?
