I have read many threads about 308s Injected running on 4 cylinders and it being linked to a bad coil, ignition box, flywheel sensor. How do you go through each, test each to figure out which is the one giving the problem? I can see that it is a no spark issue but are there resistance values for the flywheel sensors so they can be tested and if so what are? Where is the best place to begin on this, order of operation. Thanks.
