Seven Codes on this Hemi? Really?
2011 Hemi misfire has produced 7 codes.
PO 305 - Cyl 5 misfire
P1303 - ??
C0008 - ??
P2314 - Ign coil E Secondary Circuit
P2308 - Ign coil C Secondary Circuit
P2305 - Ign coil B Secondary Circuit
P2302 - Ign coil A Secondary Circuit
After installing a new ECM from Mopar.
Suggestions anyone on where to start repairing this?

Did you have the software installed in it and the security code programmed? Mopar PCMs come empty.
Those coil codes are basically open control circuit codes. 1,2,3 and 5
C0008 is a communication code. P1303 isn't in the service manual DTC list.

We swapped the injector with number 3 cyl, misfire stayed at cyl 5. Ran a smoke test throughout the intake but could find no leaks.
Am wondering if people who replaced lifters had intermittent or continuous misfire.
This engine will start up and run perfectly. Have not heard a tick, tap, rattle or noise of any kind from it. Let it idle for a while, will start misfiring.
When driving it will run smoothly, then begin misfiring, starts running smoothly, goes back to misfiring.
I suspected the harness, it looks great from the outside, can't find any damage to it.
Ideas?

At this point, you're going to have to get someone who can watch the data on the scan tool live and come to a conclusion. Possibly recheck the compression and even do a cylinder leakdown test. I would also revisit the broken valve spring. They often pop out then back in to place and it's hard to see the break in the spring when it has popped back into place and covered in oil.
