She was working perfectly last night.

Got in to go to work this morning and she won't start.

Starter motor is turning the engine over, but no evidence of firing going on.

No warning lights.

It has got petrol in it, but I couldn't smell petrol at the end of the exhausts, so i'm guessing that it may be a fuel pump issue.

Whatever it is, it's temperature related. Anyone got any ideas?

Can you hear the fuel pump prime after you've disabled the immobiliser?

Check your fuses in the boot - there are a few that I used to pull to disable the fuel pump / injectors / ignition system. The fuses are detailed in the pocket book, that's where I'd look!

Mine sometimes does this. I find an hours trickle charge does the trick - would seem that sometimes there just isn't enough initial 'oomph' in the battery - easily remedied with a short time on the trickle charger

as above really you need about 10 volts to make the ECU work so charge up then try it

Thanks for the help guys.

I'll charge her overnight and see what happens.

Maybe I should have tucked her up with a duvet last night.......

Just check that you haventt accidentally turned that little Chrome key in the cubby hole - You know, the one that none of us ever bothers touching! If that has been knocked just a bit, the engine will turn, but nothing else will happen.

Hmm, didn't think of that. Will check, although the last drive was to change spaces in the car park outside my house, so the battery could just have been feeling a bit down, then the cold finished it off.

On a different note - what a bloody daft design! Went to attach the charger, then had to go off and hunt for allen keys to get to the battery!!

We shall see what happens when I press the black button tomorrow morning

You can connect up to battery with the panel in place. Put the negative on one of the air box brackets.

Think its all dead then. I did this a few weeks ago.


Have you been messing about in the fuse box?

I haven't messed about in the fusebox at all.

The battery was fully charged when I got to it this morning.

Absolutely nothing Starter motor turned the engine as before, but no evidence of firing.....

If the fuel pumps priming and you have a spark then it sounds like a immobiliser problem.

After interrogating Andy @ APM earlier, he's fairly sure that it's a voltage issue.

I'm gonna hook up an extra battery to it at the weekend and see if it gives it enough juice.

By fully charged, did you measure it with a meter to see if you had at least 12V (12.5V might be better). I know my BEC has trouble starting with less than 12.5V, the spark is too weak.

A good earth point is on the fuel rail (if it's a 4.2) or on the oil filler cap.

Do you hear the fuel pump prime when you push the button. If you push once you can hear it pressure up and then stop, then push and hold to start.

Try jump starting it with another car. Should help if it's a voltage issue rather than waiting another night to trickle charge. Make sure you get a good contact, it's tricky with the battery cover surround in place.

The silver key should kill everything.

Mine has a short lead, about 300mm long, for the trickle charger permanently connected to the battery lugs.

There's a jack plug on it and the two just push together without any messing about with the panel.

It was on the car when I got it, and I've never actually used it, but it looks very handy for what you are trying to do.

If it's not standard on the trickle chargers it should be pretty easy to make one up.

I bought the cigar lighter adapter for my optimate and plug it into that. I don't have to open the bonnet then.

Perhaps for some reason you have tripped the fuel shut off switch in the boot.....
