Cuts out

[oddbod]

Could we have a list of, and fixes for, Minors cutting out when running. Mine is fine then stops suddenly, turn the key a couple of times and it goes again. So I'm thinking not Fuel Pump. It cut out on a down hill section yesterday and I tried to "bump" it while coasting, it coughed a couple of times then stopped. Turned the key twice and away it went again!

if this does not happen normally it could have been fuel vaporisation its been very hot recently .

[oddbod]

I read posts on fuel vapourisation Dale, but this has happened a few time and I am pretty sure temperature isn't an issue as it has happened on cooler days. It seems to happen every few journeys, and once its happened happens a few times in a short distance then doesn't happen again for a few journeys, which makes me think its probably an intermittent blockage, rather than a fuel pump issue. I am hoping to clean the carb/internal gauze filter later today.

Mmmm, just worked out that my Traveller has a HIF38 carb, and a non standard fuel pump. The pump looks similar to a standard Moggie one but hasn't got a Nut to remove the fuel filter from. My set up is: 1275 290G cylinder head, HIF38 Carb with a Breather from the engine block to the carb, mated to (I think) a Metro Turbo exhaust manifold and a larger exhaust. All this means I'm finding it difficult to follow Haynes or Workshop manual. Can I fit my spare,standard Fuel pump to this HIF38 carb or do I need more delivery than standard?

Correct me if I'm wrong but the SU pump is a pressure pump, i.e. when the float bowl is full it stops pumping, so the fact that the engine uses more fuel should not affect it - it will simply pump more fuel.

[oddbod]

I think you are right J.J. about the delivery method of the Standard pump, it fills the bowl as it empties, I am only checking cos I do do some stupid things when I am oblivious to further problems caused.I didn't do these alterations to my Traveller,they were done when I got it, but by looking at the pump it is slightly different to the one on my Saloon. I'm not inherently mechanically minded so any advice IS helpful, don't underestimate my lack of knowledge on Moggies either, I am learning,but this is a new thing and my brain is old

I have the same carb set up as you describe and run on a standard minor pump with no problems.

Clean out the fuel lines and filters so that no muck or rust is in the lines and check no air is entering the fuel line. If there is any rust or muck in the tank the fuel ine maybe getting partially blocked from time to time the fuel tank may also need drained and cleaned out.

[oddbod]

Thanks Jeff, as you seem to have the same set up could you describe where the filter is on an HIF38 carb. I am dim when it comes to mechanics and need detailed instructions to follow. I looked on the Burlens site and saw an exploded diagram, but no corresponding list of components so it was a jumble of bits to me!

I had a similar problem on my car I traced it to bad contacts on the fuse box It would run for miles then only a few yards I bypassed the fuse box with a direct connection from the battery to the pump prove it

Oddbod, the only filter is in the bottom of the standard minor fuel pump. It's just as easy to remove the pump to get at the filter which is in the bottom under a brass coloured bolt head. Remove it and clean in out (wash it in clean petrol) and put it all back together. While you have the pump off take of the top plastic part where the electrical connection is and give the points a clean with emery cloth or similar as this might save you problems later.

Hope this helps. Jeff

[oddbod]

Thanks for the advice Jeff, so am I wrong in thinking that there is a filter in the standard Moggie HS2 Carb?

[Tom and Maria]

Yep, no filter in an hs2 that I've ever found.

And the fusebox plays no part in the power supply to the electric pump - or the ignition.

[dalgrae]

I was only stating the problem I had on my car, one of the terminals on the fuse box covered the pump/fuel gauge and the trafficators whether this is correct or not to the wiring diagram I do not know or care I was stating what effect it had on my car I thought this was going to be a friendly club to belong to but not for the first time you seem to give out good advice but your tact is something to be desired .I will give it serious consideration prior to any further posts I might make and will seriously have to consider my membership renewal because of your caustic comments

[bmcecosse]

Hardly 'caustic'! It's a matter of fact that the fuel pump and ignition DO NOT pass through the fusebox. So you need to look elsewhere for the problem you have. Always happy to help with best advice I can offer from a distance - but that has to be based on the information YOU give us.

[lambrettalad]

Ignore the rest the advice is the very very best

[JOWETTJAVELIN]

Running a wire direct from the battery to the fuel pump is a very bad idea and asking for trouble.

[lambrettalad]

I didn't say it was always right

you pays your money and you takes your choice

[MarkyB]

I'd suggest looking at the ignition switch and the wires that connect to it.
And the wires to the coil while you are at it.
Petrol delivery problems generally give a running out of steam feeling rather the plugs been pulled that you get with an electrical fault.
Is there a sudden flurry of activity from the petrol pump before the engine will restart?
