HI hope someone can help I have a 2001 focus it starts then it dies this is what I have tried so far tested fuel pump and relay both working checked the shut off valve its OK I even had the key re chiped and coded as I was told it would be the imobiliser it did not work I dont know what else to try can you please help
Thanks don

 

It's going to get even more expensive if you just keep stabbing in the dark.

It could be a hundred things.
Are there any fault codes recorded?
How long does it run before it dies?
Has it got fuel?

 

If it's got a idle valve I'd clean that first with carb spray cheap fix if it's dirty

 

It only runs for a min it has fuel and a mechanic had his metre on it and it did not seem to record any codes

 

The fuel pumps are bad for clogging up,you need to lift the rear seat,cut the hole in the floor bigger then remove the pump.
Mother in laws focus has had 2 pumps over the years for this.
There's a fine gauze on the pump inlet and it gets clogged with dirt or a gel substance.
It's free to check it,alternatively you could drop the tank but that's a load of hassle.

 

I agree with above, sounds like fuel pressure or starvation

 

Change the fuel filter while your at it.

 

The mechanick and auto electrician that are working on it tired an electric pump under the bonnet and it still does the same starts and dies they were putting it on a ford computer yesterday I am still waiting on the result.

Thanks everyone for there quotes it has been helpful
