Aug 2011 at 19:29 more of a question really than an answer but my 2.2 has a coil pack which is all 4 in a row which sits over the plugs so if one coil goes down is it possible to replace just the one or do you need to get the whole shabang?

Aug 2011 at 20:00 oh when it rains it pours, when you had your fuel pump problem did you check for spark because if so maybe there's a chaffed wire leading up to the pack or bad connection, maybe a long shot but i would check the wiring before investing in a new coil pack

Sep 2011 at 13:11 Question is, how are you testing them as to do it correctly you need a large gap test plug to simulate the required 30-40mm gap. If you work on a small gap you get no indication as to if the coil is ok and can also apply to low a load to it which may damage it.

Does the same apply to my issue on an X20XEV? I tried checking the sparks with a spark plug in the end of a HT lead and a jump lead from there to the battery negative.
