I have a Citroen C2 VTS 1.6L 2007, with a very similar problem to; Unable to start the vehicle depending on how long it has previously been driven I am currently trying to fault find.
Symptoms: The car will not start when the key is turned on in the ignition. Somethings I can here small relays and the solenoid picking up and other times nothing happens. Sometimes only the small relays pick up. I clutch started the car and after driving around for 10 minutes the car came up if a fault on the inside display, 'electric circuit fault'. What I have read on the internet is this fault is a separate fault to do with my alternator?
I have pulled out the starter motor and tested it on a 12V supply. It worked fine. With the starter motor disconnected, I tested for 12V at the starter motor connection terminal with someone else turning the ignition on. I should have had 12V, but did not get anything. I tested the battery and it was fine.
Can someone please help me with this?
Also the solenoid is not located directly on top of the starter motor like most other cars. Does anyone know where it is located on my car?
