I have looked at it this morning but as i had no torx bits in my tool kit i could not remove the coil pack / HT lead to assertain if there was a spark or not. Lone behold the first time i tried to start it it fired straight away. I appreciate the i am only offering limited information but are there any common faults with this car that would give this problem?????? Thanks for your help
I have had starting problems also , the engines kicks over fine just wont fire , turned out to be a bad connection on the TDC sensor , this connector is sitting on the top of the water pump ?? right on top of the engine ,purple and black wire , I just jiggle this connector and it works every time .. I have heard lots of stories about poor electrical connections on this model
A week later :; same thing again, engine turns over ,but all the connections seem ok , so the TDC sensor stuff above is rubbish !!! reseated the engine fuse- box fuses , no joy , pulled the two large relays in engine fuse box, put them back ,,bingo , starts OK ..Im suspecting either of these relays , one of them is the fuel injection relay , I will replace these next week , could be sticking/burnt out.............
A week later .... no more starting problems : must have been the FUEL INJECTION RELAY ,Renault say "they never give problems" so it must have just been a bad seating/connection , which is OK now ???
