1.1 fiesta starting problem

First thing I'd suspect is the high tension system (faulty plug leads especially). Wipe over the plug insulators too. With engine sitting cold for some time, dampness can condense and short out the spark. This is especially important where a car has been exposed to salt spray near the coast.

i have sprayed all the plugs leads and electrical wires with wd40. the car does get used daily and dont missfire witch i wood off thought wood happen with faulty ht leads. i have had a sensor replaced under the inlet manafold (this car has single point injection) as i thought it was a problem starting cold. some one said about the crank sensor has it has some thing to do with fuelling and the spark?????????

Humidity effects on HT components can be limited to the first start of the day. I'll leave the ECU possibilities to someone who knows more about this car.

I suppose you've cleaned and gapped the plugs?

Has it done this since you've owned it? How do you start it? Are you using the accelerator at all when you try to start it?
