Question about Ford F
My daughter has a 1998 Mazda Familia and had a similar problem with her car. She took it an auto electrician where they checked the engine computer 'fault register' and the two items with fault codes were the Knock Sensor and the Cam Position Sensor. The Knock Sensor had 'melted internals' and they replaced it with a good second hand unit; they also replaced the worn spark plugs. The loss of engine power continued. My daughter

Ok a lot of people have been having problems with starting a idle running problems with ford zetec and zetec SE model fords of the 1.25 and 1.4 focus flavors.often without any dash board warning lights to signify ecu problems.
The main cause of these problems seems to be with the ignition coils and the fuel cut off switches (situated in the rear left of the glove boxe) "remove glove box its on the left with yellow cap" the easy way to check firstly the for coil failier first is remove plug 4 if it has a black line down it's side thats the problem! it is often wise to change not only the coil pack but the plugs and leads also. this instantly solved idle problems on 2 fords i have been working on. finaly the fuel cut of switches which are of bad design often fail and "pop up when jared" by speed ramps etc replace the faulty part with new one.
Second hand coil packs are pretty common and available in most scrap yards for about £20.00
New hope youve got a deep wallet over £100.00

Hi i had a ford fiesta 1.25 and i had problems kepping it going aswell. it turned out to be under the rear seats we had to drill a hole to get to the fuel tank because the wiring plugs to the inbuilt fuel pump had vibrated so much the wiring pins had disconnected themselves. id check that if i was you, it worked for me and never had a problem since.

Ive just removed my ECU tonight, yea i earthed my self too just like when i build my computers :) and disconnected the battery it slotted out a treat, so if i match the exact number and ecu code will i just be able to replug the new one in and no need for keys and transponders ring and all that stuff. Also ive had the car standing for a day and its totally dead now normally after you leave it standing you'll hear the fuel pump kick back in but now the fuel pump is not kicking in what so ever...so i assume its the ecu that has had the effect, altho they must have done something because when i took it from ford it ran a bit further then normal but now nothing. I did unplug and replug my ecu tonight but still the same thing just dead no fuel pump noise from the back but i do hear the clicking of the relays at the front.
So just to confirm as long as i replace it with the exact ecu there is no need to change ignition barrel and keys etc etc....im just scared that its also something to do with the ignition and immobilizer which i do know is all linked to the ECU/ECM, there is defiantly been water leaking in as i can see marks of water drip around this little black cover that sits over the ECU/ECM im also going to check the wiring to the fuel cut off switch, is there anyway to by pass it/short it, it has not been activated as it is still in it lowered position but i fear maybe water could have damaged the connections just another thing i can check before i get another ECU. i also removed the cover to the ecu and the circuitry looked totally sound but obviously damage on electrical components are rarely visible.
My ECU is
