Ignition Coil Failure

[Woolley91]

Hi I've recently replaced my ignition coil on my mk6 fiesta due to misfiring on cylinder 1 after looking at the old coil u could tell it was blown on cylinder 1 port but now after replacing the coil cylinder 1 is misfiring again replaced leads and plugs but it's just not spark for cylinder 1 so ino its to do with the coil but this time the coil looks fine I'm not sure wether it's just bad luck as was a second hand coil or is something else causing the coil to fail on that one cylinder 1 plug any help please before I replace the coil again

The coil pack is prone to failure on the mk6. It's possible you bought a cheap, dud part

I was actually one my cousin gave me he's a mechanic and took it off a 1.8 focus but said would b fine as was from a zetec engine was fine for two weeks just thought was strange as sane cylinder gone guess just buy new one hope for the best I wondered if maybe loss of compression or maybe the injector mighter been causing it but thanks for the reply
