Can it be done? - Page 2

Today's fun:
Basically I cleaned the points as someone (elsewhere) suggested, tried the plugs and we had a spark. Pretty happy with that we had a bash at getting it going but alas nowt doing.
So, off with the air filter/housing, gently opened the piston and put some more fuel in, tried again, almost caught, few more tries and it ran! Ok, not brilliantly (little lumpy) but we're not at all bothered about that as probably still some dirt in carb and car hasn't run in six years anyhow.
Alas once fuel in carb had gone it wouldn't run again so we moved onto the fuel pump. Took the pipe off at the carb end, put into clear bottle and turned ignition on. Zilch. Pressed accelerator pedal a few times. Zilch. Turned engine over. Zilch. Took pipe off pump end to make sure it (pipe) wasn't blocked. Zilch. Hmm, pump is defintely different to how described (on another forum) as in there was no visible way of opening it or finding any points etc. It looks quite a modern unit so maybe that's why?
There's one spaded wire running in from the loom which goes to it and sort of three wires out of it which apepar to be earths. Took earth wires off and cleaned up earthing point on body but still naff all.
The pump is a round black plastic or metal unit which seems like it's sealed and has 'top' written on it at the top (obviously!).
Fair to assume pump is knackered, should I get one of those electrical screwdrivers on the yellow spaded wire to test for current and if no current would it be safe to run a wire direct from 'plus' point on battery bearing in mind it's alreay earthed? If the wire from the battery caused it to work I'd guess that's worse case scenario as the wiring must have a break in it somewhere and I'm thinking it wouldn't be safe to leave a direct feed from battery on it?
Being honest I'm hoping we have a live to the pump and it's the pump itself at fault as this should be easy and cheap to change I would have thought?
Chuffed to **** we had it running, albeit briefly and we can hopefully get cracking on the other jobs once we've sussed the fuel pump.

Quite surprised that it has an electric pump, I assume this has been fitted somewhere along the line by someone.

I'd take the pump off and run a live through it, making sure that all the petrol is out it for obvious reasons

I have a farmer mate who knows loads about Moggies so if theres anything I can help with then let me know

Allvaux · 30-09-2008, 19:50

Cheers Lugy. People on the MM forum say it's best to get the original type pump for it (about seventy quid I believe) but I think we'll try a new electric one on it for now as want to work to a budget and start concentrating on other jobs. Popular opinion suggests pump will be shagged which I'm happy with as seems the easier/cheaper option to me. Found a second hand rad which we've got to pick up yet and have a small piece of pipe on it's way. Then we'll have to find some new water hoses as the ones on it are older than Wayne's undercrackers and nearly as worn out.

you should be hearing the pump clicking as soon as the ignition is put on,but they do have a bad habit of sticking! have you tryed tapping it with something?

Allvaux · 01-10-2008, 05:45

Yes mate, and naff all happened. Will try and find a pump for it today from a local parts factor type place.

Dell Balallan · 06-10-2008, 17:25

Any luck with the pump?

Allvaux · 07-10-2008, 05:01

Bought a universal one (just under thirty quid) but fittings are, erm, 'strange' and I'm not convinced I can make it safe to use so I'll keep it and make a rig to syphon diesel from scrappers instead!
Local-ish scrappy has a few Moggies in apparantly and I'm going to call them back this morning to see if they have a pump. Failing that think I'll have to bite the bullet and buy a new genuine part, about £70 inc. postage I believe.
Meanwhile progress slow as found other things to occupy my time and my lad hasn't been well so didn't really want to work on it without him as it's a joint thing and we are both enjoying doing it.
Basically I found some battery leads off an old car in the garage which I'm fitting because the ones on the car are the old ones which screw into the battery (like a Pug 205) and the battery I bought for it doesn't have the lugs with holes in. It's a straight forward job obviously but need to trim some extra un-needed bits of wiring off the replacement cables. Hoping to get the rad for it this week, maybe the scrappy will have one but if not know of another one anyhow, so we'll fit that and the short piece of hose in front of the water pump and see how we get on. Can't wait to get the pump and see if we can get the car running ok, that'll be a major plus and spur us on I reckon.

Fix it, MOT it, sell it. Doesn't look to bad.

Allvaux · 07-10-2008, 07:39

Nah, going to drive it for a while if we get it roadworthy.

**CraigGreen** · 07-10-2008, 09:46

THE worst in the world is a moggie on overrun.

Good to see you have your teeth into a project though mate.

Allvaux · 07-10-2008, 17:26

Cheers Craig. Bit of an epic fail moment today though: temporarily rigged up the universal fuel pump, turned on ignition and then the great petroleum escape committee started as fuel pissed out of every available point. It seems my fuel lines were in a worse state than I thought but was going to replace them anyhow, it's just the pump is possibly too powerful plus the unions I cobbled together obviously didn't hold. Definately time for a proper fuel pump for it.

Steve_rsa · 08-10-2008, 12:55

The universal is probably a universal Fuel Injection pump. They run at far higher pressure than the old carb pumps.

And a box of matches!

Fire rats!

I think that was the problem mate, cheers and lolzers at Craig!

Anyhow... ****ing get in there, it's running! Got the original type pump for it and some braided fuel line (Bull Motif) and as advised elsewhere went to a plumber's merchants. They supplied a screw on fitting for the pump and told me I'd need 10mm copper pipe ideally. Only did a large roll (twenty odd quid) so I whizzed down to B&Q as I also needed some sort of 'male' joint to attach the fuel line to. B&Q supplied the joint but no joy with the pipe as again large quantities only. Anyhow I also got some fibre washers as the pump has one fitted and with putting the joint on I didn't want to take a chance. So, after a careful check of what I needed, I got cracking this afternoon, fitted the original type pump, connected everything up then checked/double checked/quadruple checked everything was on tight and in the right place and turned the key. Pump definately working but quite noisey and car ran but wouldn't rev up, then stopped altogether. Neighbour was near by and he checked the one small piece of old fuel line I temporarily re-used and discovered it was blocked. Different piece of fuel line on, all connected, pump goes noticeably quieter (so obviously being loaded with fuel) and I tried again. Bingo! Running and ticking over no bother but not firing on all four. The main thing is starts on the button and will stay ticking over so that's a massive result. Next is change oil and filter again, replace badly leaking rad and small piece of pipe so I can leave it ticking over for ages again, then check whether it's the leads, the old fuel or the points that need looking at to make it fire on all four. Engine sounds fine apart from mis-fire: no knocks, no rattles, no bangs so really chuffed with it now.
Oh, one thing I will need is about 6 inches of braided fuel pipe to go from metal fuel line and fuel pump. The problem here is the line from the tank is fairly narrow but the part of the pump the line needs attaching to the other end is wider so I need a sort of flared braided fuel pipe, one end wider than the other. Is that the kind of thing I could buy/have made from somewhere or do I need to adapt somehow?

Pictures of pump, as I say need more fuel line and some checking again afterwards...

New braided fuel line...

Arsing about with the T-cut, quite a difference and I've not even put much elbow grease in yet...!

Hey it's a labour of love fitted in between three jobs, a mad missus and two demanding kids not to mention weekends spent drinking and watching football!

Good result mate well done

Hoping to have some slot mags for it in the next few weeks.
