You need to do the checks when it has conked out 'hot' otherwise you can miss the problem :( Do you still get a spark when it conks out? [Check by removing a lead and connecting to a spare plug - rest it on the block / head nuts to earth it] Do you still get a good flow of petrol to the carb when i...

Probably not the coil then if the old one and the new one both did the same thing. yep.... I'd agree. My ideas........ Overheating? (Gives similar symptoms to running out of fuel, and a dodgy thermostat would be the most likely culprit) Blockage in the carb (even though everything I've looked at se...

It's had the exactly the same symptoms for ages and all sorts have been replaced including the coil.


Totally stumped!

ARGH!!!!! I 'm lost!

(it's got a brand new coil and condensor)

Ok, done the pint in 2 min test and it managed it easy! No dirt in the pump either. Today it was idling for a while and eventually conked out, a first for that! Thinking it might be a stuck thermostat now? As there's no dirt in the fuel and the pump is fine, and the car only dies when it's heated up...

Hmm, will look at that end!

Going over to do it in a min'!

Have you tried cleaning the filter on the bottom of your fuel pump?

Hmm, I'm not sure if it has one!
It's a brand new one but it seems to be a sealed unit.

The filter would be at the far end away from the inlet outlet pipes wouldn't it?
(that's covered in blue plastic/tape stuff on this unit)

Some replies and questions............ Cleaning is only with carb spray and a cloth to wipe away any residue. I will try the pump test, going to be working on the car this afternoon. The in line filter can't do any harm, it's just a method of catching dirt before it enters the carb. Is it worthwhile...

Right..... it's all coming together slowly (I'm far more used to the likes of Weber carbs!). Under the damper stalk theres a brass jet like circular part with a hole in the middle, I'm assuming I should be trying to lift whatever part this is fitted to to check the spring? Also where else in the car...

No - not having enough oil in the dashpot will only cause a problem on acceleration (assuming you still have a spring in there). Still going to be a fuel supply problem. Try rigging up a temporary tank from a jerrycan to the inlet of the fuel pump, if the fuel pump tests out OK (see above). On the ...

Hmmm... any other car I've had before would have the plastic in line filter completely filled up, this one only before it's been driven for a bit.

Could the plunger not having enough oil on it cause these symptoms?
(Some was definately lost during cleaning)

There should be a steady clicking from the pump and strong steady spurts of fuel into the container. It should be able to pump 1 pint in 2 minutes It seemed to click away fine and fill up the filter well when cold but when it was having trouble driving the pump was still clicking but not filling up...

If the (clear plastic) fuel filter isn't full then you have fuel supply problems upstream of that .. blockage/dirt in tank/kinked fuel line/wrong fuel filler cap/blocked vent or fuel pump (if this is fitted upstream of the filter). Phil. Cheers, I was thinking it might be a problem at the back of t...

Hi there, Having trouble with a standard SU carbed Morris 1000. It seems to be running out of fuel or have a fuel blockage. So far I've cleaned out the fuel bowl and fitted an in line fuel filter, but after the car has been driven for about 5-10 min it starts spluttering and chugging.... eventaully ...
