My car has started in the last 2 weeks to cut out as I drive along.
once stopped, i turn the key, starts right away. I started not waiting to stop, just turn the key and off we go again.

It has been suggested to me that the fuel going into the carb may be too dense because it is so cold and as I have a k&n filter, there is no heat coming off the exhaust to warm the air going in.

I have also recently put a luminex (i think thats the name) electronic ignition, could this be at fault?

the car runs sweet normally, and even once I have restarted it goes really well, strong.

could it be the fuel pump?

mine is in the engine bay, I am told it should be under the tank.

any ideas gratefully taken,

Zed

Fitting a k&n won't effect the exhaust in any way, they'll be heat coming off the exhaust. Cool air is better for combustion anyway so you don't want the exhaust gto heat the air.

The fuel pump is in the engine bay apart from on injection cars (ithink)

Did you have any problems before you fitted the electronic ignition?

I had a similar problem, turned out to be a bit of 'something' in the fuel line just above the needle valve. Sometimes it blocked the line and other times it prevented the needle from closing with the resultant fuel all over the floor from the overflow.

Rather unlikely to be 'freezing fuel'.

I'd put money on it being your cone filter to be honest, i used to have problems with it aswell as it is your fuel vapor/air mixture freezing ! Loose the cone filter and youll have no problems.

Petrol won't freeze in these conditions.

You might be referring to carb icing. This is when water vapour in the air is made to freeze by the fast moving low density air flowing through our SU carbs, causing the piston to stick and stopping it from moving with engine speed - causing it to stall.

Quite rare in minis because of the location of the carb over the exhaust. Eliminate all other options first before assuming this.

Petrol starts to freeze from -50c downwards so it is impossible for it to freeze in these conditions

Carb icing is what i was refering to aswell ! i had many many nights in the winter where this would happen to me so i wouldn't call it rare to be honest

Hi, Is there a simple answer, my mate suggested getting some ducting from halfrauds and running it from above the exhaust to somewhere near the air filter. not far but he thinks it would make a difference. the original filter has a pipe that does this job.

I don't wont to curse myself but my car doesn't get very hot, at most it's just under half way and when it's cold and ~I have the heating on, you can see the temp gauge coming down to just above the blue bit.

thanks

Mate, if it was -50C outside....you'd know about it.

And actually carb icing is more likely to happen in humid conditions rather than being plain cold, as it is predominantly affected by the moisture content of the air.

Yep, doing something along these lines will help. Make sure you eliminate anything else it could be though as I said before

If its not getting up to running temperature then it may be worth checking you have a thermostat.

This could lead to poor running in cold condition, and will also increase engine wear, on top of this, having no heater is PITA!!!

I spoke to the mechanic that fixed the head gasket, he told me he put a new thermostat on when he had it all off.

could it be that the sender is just not accurate any more?
