Hello Chris

Does the pump ‘tick’ when the ignition is on? These pumps have points in them which tend to stick when left unused for a time. If you cannot hear an audible tick, then the points are likely to have stuck, and the pump will not be able to suck the petrol through.

Just trying giving the pump a light, but sharp tap with the ignition on, and see if it starts to tick. This often cures the problem if the points are only slightly stuck. However, in either case, I would recommend you to check them and give them a clean. Again this is quite simple, just remove the bakerlite end cap, by removing the feed wire and then unscrewing the little brass nut. You can then see the points. With the ignition off, run a fine bit of emery cloth (or even a nail file), between the points until they look clean and can be opened against the spring easily. Then try it all again. If the points are badly corroded, you may need to remove them from the pump and give them a good file.

If the pump is ticking, and still no fuel is getting through, check the little fuel filter at the bottom of the pump, at the other end to the bakerlite cap – this may be clogged up. Lastly, the diaphragm may have deteriorated and may need to be replaced, but I suspect the problem is most likley the points or filter.

All replacement parts, and even reconditioned units are readily available from such places as Burlen Fuel Systems.
