Hi all, I've got an issue on my 2003 172 cup where it intermittently wont start, cranks, immobiliser light goes out and I might be imagining it but it might sometimes shake a lot as if it was misfiring, but not really coughing. When it eventually starts it's obvious from the smell that it has been putting fuel in.
It started off occasionally only when warm but quickly got worse to the point I can't go anywhere in it because I'll probably get stranded.
I have replaced the crank sensor and this has made no difference.
It appears that the issue is a lack of 12V supply to the coil pack. Not sure if also affects fuel pump (they're on the same relay afaik).
Any suggestions/known issues?
The tricky bit is this started a week before I left the country for work and I won't get back until late on the 22nd, so not much chance to fix before Christmas.
The main thing I'd like to try is replacing the fuel pump/coil pack relay but not being there I can't get a part number for it so hoping someone can help. Renparts couldn't get a part number from the reg, they even phoned Renault who said the same, part number or bust.
Can one of you lovey folks try to get a part number for me please?
I think but would appreciate confirmation or correction, that it's a small-ish rectangular dark red thing, there are two of these at the front of the fuse box with a big grey one just behind them. (One for fan and one for pump & coil?) I did try swapping them to no avail.
Suspect either both are coincidentally broken or it may be the wiring somewhere in between.
Are the female connectors known to go? Can they be individually replaced or do I need a whole new fuse box including desoldering or decrimping and redoing every single connection? Is there maybe a connector or two to unplug the whole fuse box?
Edit: Had the RAC out for it once and fault codes for coil pack came up and the guy checked the 12v feed. He also said on the time it did start that he heard the fuel pump going whereas I couldn't tell over the throttle noise whether it was running or not.
