p0353 cyl 3 no fuel or spark so I been having a bad mis/stumble in my truck the past few weeks kinda hit or miss. well now it looks like its here to stay. truck is throwing a p0353 code and I have no spark on cyl 3 I have swapped plugs, wires, and coils an it stays with cyl 3. I also swapped out the main coil harness connector and still having this problem. Fuel pressure is good and I have checked continuity from coil plug to pcm for the signal wire an it showed good. Coils all have a goo ground and 12v with key on. Also wideband goes lean when this happens and truck shackes bad. idle is not so bad but as soon as you put it in gear it goes to missing. So my question is what could it be that I am missing to make just one cyl not fire?
