95 Fiesta 1.1 CFi
(Central Fuel Injection)

Spent the day trying to fix my cousins Fiesta for him. Can anyone help?

It wouldnt start. But turned over OK.
- Battery and starting system fine.
- Spark is good and plugs are new but a bit black (running rich perhaps or maybe just due to him trying to start it).
- Air filter is OK, no probs with in take and all vacumm pipes appear to be connected correctly.

I believe problem to be fuel and disconnected line to ensure fuel pump/filter not blocked. It wasnt.

I have now managed to start the car but the way I did it was very strange.
I was about to remove the injector to ensure it wasnt blocked and so set about de-pressuring the
fuel system. To do this I pulled the fuel pump fuse and turned the ignition key to empty the fuel in the line via the engine.
To my amazement the car started and the engine ran until the fuel line was empty.
I replaced the fuse and turned the key again and it started straight up!

I stopped it almost immediately and waited for a few mins. Then tried to start it again but no joy.
Pulled fuse and it started good and died when fuel ran out. Replaced fuse and it started and ran fine.

Couldn’t repeat this any time after as it now just seems to start up fine each time (fault cleared or engine warmed up enough). Longest it was left off for was 30 mins and it still started fine after that.

I have a feeling that the non starting fault will come along again. Does anyone have any ideas what it could be?
I have heard that the CFi CVH engine can have starting problems and wondered if there was a common fault.

Thanks for any advice.

Very common problem with any ford fitted with single point injection.
Usually worse in cold weather i looked at one only today with exactly the same problem as you are describing.
Try and avoid touching the throttle when starting from cold, basically its a design fault that floods the engine.
If it should happen again take out fuel pump fuse crank over engine with your foot flat down on the throttle for as long as the battery will cope , then pop the fuse back in and it should start.
Hope this helps.
