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.

Try this but the fault I have is intermittent so may take a bit to work out - switch off everything in the car so there is no noise. Turn on ingnition (do not start) and listen for the sound of of the fuel pump below the rear seat - behind the drivers seat. The pump should run for about 5 - 10 sec then shut off, it may work but if you cannot hear it it may be an ECU issue. If it does run start the car and drive it until it stops again, switch the ignition on/off and listen for the pump running. if you can confirm that the pump is running intermittently you have the same ECU problem I have. The official solution is to replace the ECU - ££££££. The low cost alternate is to run a wire from the ingnition controlled feed at rear of the radio and connect to the pump feed at the fuel tank, ensure a correct rated fuse is installed somewhere along the wire. There is a least one issue with this - if the ignition is on the pump is running, so not a good idea to sit with the key turned to listen to the radio.

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...
