Could you clarify what you mean about the "dials going crazy"? What did they do?

Was everything normal when you turned the ignition on, but then it behaved strangely when you turned the key further to start it?

In the dim and distant past I had a similar vintage Mondeo diesel and when I experienced this it was down to a knackered battery so worth checking that first...

Did the average mpg and trip odometer reset when the dials went crazy?

All dials went to max even fuel, the trip odometer reset to zero
Turned ignition off waited a while then all was fine.

Failing battery - or at least exactly the same symptoms as when batteries failed on my Mondeos. Three years is a bit of a short life for a battery, unless it was a very cheap one, or under-specified.

To avoid being over-charged for a new one, check out the price for a battery by entering your reg. number on the Euro Car Parts website.

Battery has a 4 yr guarantee iv managed to find the receipt, ok so that's the first place to start.
Fingers crossed it's just that then x

Check the earth lead first, it might just be that that has a bad connection.

Your battery is dead. If it's only 3 years old, then the next question is why is it dead? It might be worth having a good look at the alternator and belt etc as a good place to start.

I do not believe it is the battery as all the lights on the dash are still bright as they should be, iv tried starting it today all the lights are there on the dash but turn the key and absolutely nothing it's like there's no engine in the car lol
So my next question would be where's the earth wire? And yes I really am clueless!!!

Just because the dash lights are bright doesn't mean the battery isn't faulty! The dials doing odd things like you describe is what happens the first time you turn on the ignition after having the battery dis-connected on a Mondeo so you may just have a bad connection so checking the condition/security of the battery terminals is the first thing I would do. Do you know anyone with a multimeter who could check the battery voltage for you?

Battery isn't dead, the OP has said he can go back to it 10 minutes later after it has been playing up and it will start OK then. If the battery was dead, that wouldn't happen. Its a bad connection somewhere, most likely at one end or the other of the battery earth lead or possibly an other earth lead.

Look at the battery to see which is the negative side - the wires should be black NOT Red. Make sure the bolt securing them to the battery is tight.

Next, follow the big black wire downwards, it should be attached to the car somewhere under the bonnet with another bolt or screw (The earth connection).

Check this is tight also.
