I have a 2007 suzuki xl7 and only the front 3 cilinder are working the other 3 on the back they have no spark i replace the coils,and still the same
what engine, must be the V6, sure, the H27? engineis car in usa, ?the reason i need that INFO is spark systems very by COUNTRY.you said coils, so that tells me its V6, and has 6 cops6 coils over plugs. (unlike other engine in other countries)so its like ours here. (or like the one I just sold, I now hate Suzuki)they bugged out here, so are Yogo status to me:(isuzu,suzuki,daewoo,yugo) dead dogs. all.so what do we do, well that is easy.we check fuses first. (we test the ones that look good)or read the schematic on the H engine, in the book, and see which fuse runs IGN.next we scan the PCM and the PCM sure can tell you problems.XL7, 3.6L V6 in USA car.ok, I logged in to mitchells for you.and guess what, there are 2 fueseven coilsodd coils.fuse 18 or 19, Im too lazy to look up which bank is even...its just 2 fuses, so... moot point.btw, we check fuses first on all electric failsand spark is electric.fuses that look bad, are in fact bad.fuses that look good can in fact be bad.we test them.there are 2 tests (3 if ocd)1: ohm check them. 0 good , infinity bad.\2: key on check volts, 12v on both sides,of fuse good. if not , bad. (live tests never lie)then the fuse blows again, after all that is its job to prevent fires on shorts.so we have shorted COP.3 fuses in hand find cop that is shorted.1 cop plugged in at a time.I use and ammeter, but I have tools.
