2005 CARAVAN 3.3L.
Van misfires, code says coil three . change out with new a cam sensor , injector, wires , plugs and of coarse coil. What is left and why would the pcm just have a problem with # 3.
ps i checked the compression and all six cylinders have 165. lbs.

There is a pretty good chance that you got the wires on in the wrong firing order. If not, it is, of course, possible that you damaged one of the new wires.

It is hard to say without more info. It would be really helpful to check with a scope whether there is spark current flowing through all the plug wires. You can carefully remove one plug wire at a time to find the one which, when you pull it, there is no difference. That will at least narrow your search down.
