Code Deciphers

#8
Please reference the shop manual to find out what these codes mean.
KIDDING.
P0275 - Cylinder 5 misfire - it IS missing now, or it has missed in the previous drive cycle. Injector, compression issue, etc. etc.
P0401 - EGR valve is junk.
P0674 - Glow Plug #4 Circuit
P0678 - Glow Plug #8 Circuit
I would lean more towards the GPCM than an individual glow plugs, but it is hard to say from here.
P1378 - FICM supply voltage circuit low
This can be caused by several different issues, but the most common for THIS particular FICM code is the relay or the pins in the junction box being spread not allowing voltage to flow to the 'low' side of the FICM.
V0105 - Can't find it in my shop manual.
V0306 - Can't find it in my shop manual.
I also tried substituting a U instead of a V - no go.
As for the contribution code, I would address the FICM issue FIRST before going with any injectors or anything - the FICM can cause all sorts of stupid injector concerns. I would also verify the charging system and batteries, since a lot of your codes can be caused by low battery voltage/low charging system output.
Hope this helps a little.
