car not starting

[shauno]

went to start the car the other day battery had gone flat so i have charged the battery up, no the car won't start. A mechanic has had a look at it and said they are prone to blowing the ECU when chaning batteries, has anyone else heard of this or had this problem?

I can't say that I have ever heard of this before.

I have disconnected and reconnected the battery loads of times when doing work on my S3 and never had a problem.

I would guess that if it was possible to blow the ECU when changing a battery you would have to do it with the ignition on as you connect the battery, as far as I'm aware without the ignition being on there is no power going to the ECU making it very difficult for it to blow up.

I think I would get a second opinion if I was you ...

Does the engine turn over when you try to start ?

Sorry, missed this before...

As above, I have never heard of this with the Ford unit - I have disconnected and reconnected the battery loads of times in the "S", and before that, on a Granada (same engine and ECU) that I owned for 5 years. Never had any problem. Maybe I've just been lucky...

Charging a totally flat battery can kill it.
Had the same problem: battery (1 year old) dead after charging a couple of times.
Bought a new battery and a trickle charger: works fine.

When you say it will not start do you mean that it will not even turn over. In which case you should check the battery condition.

If it does turn over but still not start then there are loads of other things to check.

How much has been looked at already.
