Not sure how you confirmed the coil isn't the culprit, but I would pull each plug and turn the engine over to see if you are getting a decent spark. If any of the plugs are sparking properly, either you have a bad plug, bad wires, or a bad coil. I suppose you could also have a majorly plugged injector that is preventing a couple pots from firing properly. Just some thoughts.Hi My 2004 focus sl 2ltr zetec engine only runs on 2 cycl and it is not the coil help?[bash]
the motor is a 2ltr zetec and the timing belt has been replaced the car has only done 98000 klms.( about 60000 mls).Welcome.
Made this it's own thread for more looks.
Any more info. on what's been checked so far?
(And detail engine type for us yanks, sometimes zetec is the chain driven cam type we call a duratec)
When you've eliminated every possible problem, and it still doesn't work, it's time to recheck some of the tests & assumptions.In answer to your input .
1. I replaced the coil with a new one
2.checked each plug individually
3.checked the plug leads.
4. checked fuel filters and injectors.
5. the motor has full compression.
I am lost and really do not want to take it to ford because they will charge an arm and a leg.
