Re: [doc] couple of tech questions

You can get the same effect with the key in position 2 then sucking on the distributor vaccum advance pipe then quickly letting go. This will move the distributor baseplate then it will spring back when you remove suction. This movement will move the pole past the stator which triggers a pulse in the distributor coil then the ignition amplifier causes a single pulse which then runs the fuel pump relay for a couple of seconds too. This is a quick check of the lot.
   
  My fuel relay does run the fuel pump for 2 secs every time I turn the ignition to 2, so does Mike Bozzys and John P's. Not checked others.

  This is not actually part of the design as far as I can tell and not all 
cars do it. it's a quirk of the ignition amplifier powering up and 
sending out a spurious pulse I think. You can achieve the same effect on 
many cars by flashing the headlights quickly with the ignition on!
