Jiglu: BMW '02 Owners: Discussion: RE: 02 just quit today

Hi Brad,
Assuming you have heaps of petrol in the tank and there is no fuel in the carb, what you can do is pull the pump off the cyl head and manually push the pump lever in and out. It will be easy firstly and then the pressure required should increase. You will feel the fuel moving in the lines as well. The diaphram in the pump stretches over time and can fail.
Otherwise, check to see if there is spark at the plugs. Distributor rotors have been known to fail for no reason.
Cheers,
John.

Could be crap in your fuel – if you leave an old car with less than a full tank you can get corrosion inside the tank and then debris when you fill it back up again. In my experience this leads to poor running though, rather than no running at all. If you’ve still got a mechanical fuel pump clean it’s filter and then check it’s delivering fuel to the carbs by sticking the outlet hose in a jam jar or something (without setting fire to your engine bay!). You can also check the fuel pick-up – this has got a plastic gauze filter.

It’s a good/cheap idea to fit an inline fuel filter ahead of the pump, and if you’ve already got one does it need replacing?

Good luck.

Nick

All,

I pulled the '75 02 Auto out of storage today and was intending to take it our for a good run. It has been laid up for about 5–6 months with only the very occassional drive around the block. I only get back to Perth once in a while now.

Prior to being laid up the car was fitted with a new webber carby and manifold from Top End in the USA <http://bmw02.jiglu.com/tags/topics/usa> along with an MSD high perfomance petrinix ignition system.

The car started up vey well and was running prefectly as it does. After a few kilometers I stopped the car at the service station to put some air in the tyres and left the engine running.

After I that I pulled away all was very normal. Suddenly after a few hundred meters the engine died completely. Luckily I was able to coast and pull it into another service station. Being Sunday it was closed. All of my tools are elsewhere in my other car unfortunately. I spent about one hour checking all of the connections. I tried another spare coil lead the I had – no luck. However, nothing seemed to be wrong when I checked all connections and fuses. The car turned over an cranked very strong – just would not start.

I am suspecting it is a fuel delivery problem because with all of the cranking I did not smell any excess fuel as you might expect. The ignition system is new with less than 200Kms on it since the webber and manifold were installed at the same time so that should be fine. Can it be fuel pump <http://bmw02.jiglu.com/tags/topics/fuel-pump> ?

Any suggestions or comments would be appreciated. I hope the car survives a night in an empty car park in Perth, WA.

Thanks in advance.

Brad.
