Hello, joined yesterday, some great technical advice btw, unlike some other forums.
I am having the same problem with my girlfriends Clio 1.2
The has ran sweet for almost twelve months until two days ago.
The starter motor had gone and would not turn, just a clicking sound, replaced the starter motor but then nothing not even a click, so after reading many posts on hear i cleaned the
sensor, still no luck, so i have tried what this guy has tried and earthed the block with a jump cable, the car fierd up but went straight round to 3000 rpm and stayed there.
Thinking it was and earth issue, i cleaned all the earth connections and battery terminals, still wont start unless the block is earthed via jump cable?
Did you manage to find the cause of the problem?
Any help appreciated
