my renault megane 1996 1.4 kept juddering while driving my husband noticed one of the earth wires from the battery was decayed so we put new ones on and it has stopped juddering but sometimes it wont start. it starts fine sometimes then other times it wont fire up, its fine when its been jumped, and when you turn the key lights/cd player all come on fine but the engine just wont start? can anyone help please going on holiday next week x

problem sorted!!!!!!!!!a very clever man suggested it could be the solenoid sticking, so my husband took it out cleaned and lubed it and it starts everytime!!!!!!!!!

Have a look at all your battery leads and earths right down to starter,if you said it improved after changing earth lead think you are on the right track
