Re: evin 235 v6
Do you have no spark, or just weak spark? Did you test each plug wire with a spark tester? It is highly unlikely that all 6 coils have gone bad a the same time. Your engine should have two power packs and are generally the first place to look for problems on the crossflows. Since you have no fire on any plugs, it would be unusual (though not unlikely) to have both packs go bad at once. (Swapping one with a known good pack will help your diagnosis.) The stator and timer base would be the next places to check. Both need an ohmmeter and a peak-reading voltmeter to adequately test for problems. I'd start with the stator-it may have no output. I'd recommend a factory service manual for doing this type of troubleshooting.
