I have got an Escort Cabriolet with a Fiesta RS turbo engine.

The car is turning over but is not firing up, I can hear the fuel pump prime, but there doesn't seem to be a spark.

It seems to be an intermittent fault, for example it won't start then abit later on it starts fine and will run for a few days with no problems then it will stop again.

I have replaced the Crank sensor and tried another coilpack.

Any ideas???

Thanks

Dan
