DTC's - Need help determining problem

[NC-Excursion]

So I checked my DTC's this weekend and got a few codes that I am not used to seeing. I always get the EGR code given that its taken care of, but these three were news to me. If anyone has any information that could help out, I would greatly appreciate it.

P2290-Injector Control Pressure Too Low
Could this be a sign of a bad/going bad FICM. I checked the voltage when I cranked it up this morning and I was at 47.0 when I fired it up and it went to 47.5 within 1-2 minutes and fluctuated anywhere from 47.0 to 48.0 on my ride to work.

P0675 and P0673 - Cyl 3 and Cyl 5 Glow Plug Ckt.
I'm guessing this could be an open circuit somewhere in the wiring headed to these two glow plugs. If this is the case, any ideas for troubleshooting.

The thought that the FICM could be headed south has me thinking. If the time comes that I need to replace it or have it repaired, I want to get a "beefed up" FICM and something along the lines of the ATLAS 40 tune. The Ex is my daily driver and I cannot afford to be without it for more than a day or two. SO that more or less requires someone that uses a deposit and exchange program. What are my options for FICM repair and programming (one stop shop) and what have your experiences been with them.

Thanks in advance for all the help.

Take care,

John

p2290 has to do with the oil pressure sensor for the HP oil system nothing to do directly with ficm.
The 2 glow plug codes are as you suspect wire issues or a bad controller.
