simonsp Posted August 20, 2010 Share Posted August 20, 2010 Good evening everyone. I broke down today and green flag said cause was coil pack. So I got one and still same problem, so I got another and still missfiring. So pulled leads off and 1 and 4 still no spark FROM coil pack. Are there relays that control each half of the coil pack? The car is a fiesta zetec 1.25. I must stress that there is no spark from coil pack on 1 and 4!! Any ideas?? Cheers simon Quote Link to comment Share on other sites More sharing options...

fordpartsman Posted August 20, 2010 Share Posted August 20, 2010 were they genuine coil packs as aftermarket ones tend be be worse than useless Quote Link to comment Share on other sites More sharing options...

james_60 Posted August 21, 2010 Share Posted August 21, 2010 Hello May I suggest that you get a diagnostic check done on the ecu. Check the Camshaft Sensor and the Crank sensor etc. The ecu is ultimately what controls what happens when the engine is running.

mintalkin Posted August 21, 2010 Share Posted August 21, 2010 are the leads and plugs ok? Quote Link to comment Share on other sites More sharing options...
stef123 Posted August 21, 2010 Share Posted August 21, 2010 these engines use the 'wasted spark' method, where the spark plugs fire in pairs. i presume that 1 and 4 are pairs so you may have a wiring or ecu fault somewhere? Quote Link to comment Share on other sites More sharing options...
