2005 caravan 3800 cranks over got spark but wont start

Ouch! A case of the raucous rodent! I've been there...Not fun trying to track down and repair all the damage.
First of all, let me explain how the code sets: The computer monitors the PRIMARY side of the coil to determine the burn time on the SECONDARY side of the coil. This can be a little confusing. The code will set when the computer determines that secondary ionization (burn time) was too short, too long, or did not occur at all.
If you have confirmed that there is no spark at the spark plug wires, then that is why the code is setting...ionization is not occurring at all. What can be a little confusing is that this can be caused by a failure in the PRIMARY coil circuit even though the code is indicating that the computer is having a problem with the SECONDARY circuit. (The secondary circuit can malfunction even though the primary side is functioning perfectly, but if the primary side malfunctions, the secondary side ALSO malfunctions - it is impossible for the secondary side to work if the primary side is not working.)
So, I said all that to tell you this: I think you have pretty much eliminated the entire secondary side of the ignition by replacing the whole circuit. So the problem must be on the primary side. (Probably more chewed wires)
There are 4 wires going to your ignition coil. The BROWN/WHITE wire comes from the ASD RElay and supplies battery voltage to the coil assembly. Since the other four cylinders are firing, This wire has to be OK.
The code you are getting is for coil #2. This coil is controlled by computer through the DARK BLUE/TAN wire. If you disconnect your coil connector and probe this wire with a test light connected to the POSITIVE battery post, it should "blink" when to crank the engine over. My guess is that it will not be blinking. You can do this also on the BROWN/ORANGE (coil #1) wire and the DARK BLUE/DARK GREEN (coil #3) wire to see the difference.
Anyway, if the DARK BLUE/TAN wire does not blink, then the wire is broken (chewed?) between the coil and the PCM.

i dont know if this makes sense, if its the big clip, you push in the cylinder and twist until the clipp comes off

3.3 engines has the egr valve with transducer.you have to replace the whole unit. code p0406 what its trying to tell you your egr valve circuit is short to ground.it has failed .
SOURCE: 2005 Dodge Grand Caravan. Code check
Cycle the key on, off, on, off. on. Then count the flashes 12 is normal 55 is end of sequence

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.
