58V FICM Software Incompatible code

[IntrnlDslDriver]

I have a 2003 6.0 that I put a 58v FICM on and it cleaned the slight miss up on it. Here recently I put a Oil Cooler on the truck and after I put it back together the truck has a PO263 code. Would this be throwing this code if a injector connecting was bad or got bent on reinstall after the oil cooler replacement? It was not missing before the oil cooler was replaced..

It's for cylinder #1, front of the motor, passenger side. Just make sure the injector clip is pushed on all the way.

Could be, and from what I've seen usually is, just a bad connection. If the connection and wiring checks out, it could be a bad injector. Not likely, but definitely possible.
