FUEL SUPPLY FAILURE

If the car will not start, although the engine is cranking normally and you have established you have 12 volts, you need to check the fuel supply. A quick loosening of the fuel injector will confirm if no fuel is being delivered when cranking.

Once you have determined that no fuel is reaching the injectors, you need to check the fuel stop solenoid. To do this in the way recommended by the manufacturer it is necessary to remove the fuel pump fully and drill out the shear bolts. This is a very labourintensive operation and these days would write off a lot of older vehicles like the 206. However, it is possible to carefully grind off the cover, for which a mini Dremel type tool is ideal. Once the cover has been removed, you need to check again for a 12-volt signal to the stop solenoid, or else use a voltage probe, apply 12 volts and listen for a click.

Removing the solenoid is simple – just unscrew it with a socket (although sizes

can vary). The solenoid is only available from Peugeot as part of a complete pump, but aftermarket suppliers can fix you up with a multi-fit solenoid, and all you need to do is install a new connection to make the solenoid operational.

This set-up was used to add security and make stealing the vehicle almost impossible – in 1990s Citroëns or Peugeots with a key pad, this is what the key pad controls.
