What is the constant clicking from fuse box behind glove box on peugeot 307 car wont start ?

SOURCE: peugeot 307 sw ignition switch fuse keeps

there are three likely problems.... check the battery of the vehicle if the battery is still ok, or the alternator is not supplying the right power and finally the fuse box has some burnt part in it internally...

Sounds like a starter motor problem. Possibly a sticky solenoid. Try rocking the car or giving the starter and solenoid a hard bang with a hammer.

whatever you do, do not take the steering wheel cover off, if you do set off the airbags it will cost 100s of pounds to get them re-packed. Check to horn itself, its usually in the shape of a flat circle and located somewhere in the engine bay, check the wires are connected to this, if they are, also check the wires going to the horn button

Please rate my help, thanks

SOURCE: can a speed sensor failing cause my Peugeot 307

an approved/competent peugeot dealer with peugeot diagnostic equipment can connect it to your vehicle and check the signals from the camshaft and crankshaft sensors. there shouldn't be any doubt about it. the engine control unit(ecu) needs both sensor readings(to identify which cylinder to inject fuel into)before it can start. a new cam sensor has a plastic nipple which should be in contact with the target plate when first fitted, this brakes off when the engine is started. it is used to ensure the correct gap between sensor and target plate. to large a gap and the sensor may not work correctly. once engine is started this info' is ignored by the ecu. the fuel pressure(measured by another sensor) can also be checked and is displayed on the equipment in "bars". 250bars of pressure are needed for engine to start. one of these (cam, crank, or fuel pressure signals) must be wrong if engine is not starting(assuming uncontaminated fuel). which one determines diagnostic path to be followed.

tour car requires a brakelight switch, u can find the switch under the glovebox.
