my fiesta st has a starting problem it seems not to start as easy as it should and some times takes upto 10 secs of cranking to start iv been told it could be a problem with the ecu as this is a common fault. could someone help

might need a ecu update what reg is it

I have a preface lift model which sometimes just won't start...take key out then back in and it starts straight away

its an 05 plate iv booked it into the garage i got it from as i have only had it a month and its got a years warranty on it.

mine does the same!!
its out of warranty now though.

i took it back tuesday to get it plugged in and it says the manifold pressure sensor is faulty so im waiting for it to come in so it can be fitted hopefully this will solve the problem.

im going to get mine checked then after its serviced.
just in case its something like yours.

Mine will do this every time if i stall it, its an 05 pre facelift. I find to overcome this take the key out and then start the engine, but this sounds a little different to your starting problem

i had the manifold pressure sensor changed on friday and there is no change it still wont start as it should

whay mods does your st have if any? and when was last service? it could be any number of very small things making it not fire up right away

it is totally standard and was serviced by the garage i got it from about 2 months ago when i bought it.

so it turns over for about 10 seconds then fires up correct

yes it seems to do it from cold and only if i drive around a mile then stop turn it of then when i got to restart it it will crank for 5 to 10 seconds befroe it will start and also i have noticed from cold when i change gear it holds the revs but is fine when warm.

is it not sluggish or sounding a bit off when its fired up and driving around?

it idles abit high when cold thats about it
