6 liter barely running...heres the diagnostics maybe someone can help

Barely runs and rough idle, no acceleration

2 codes
P0263 cylinder 1 contribution
p0275 cylinder 5 contribution

I checked the diagnostics with my scanner and heres a couple I thought might be important.. Keep in mind the truck has brand new fuel filters and a new air cleaner.

36% fuel level in
.51 volts fuel level in
100% fuel pump duty
1.2 volt injector pressure
13.9-14 volt vehicle power

I believe this is probabily a bad FICM... I replaced it not too long ago but Im sure they can fail again. I am just looking for someone to stear me in the right direction or verify that this is most likely the cause of the problem...

thanks!

Is it putting out lots of smoke? Check your EGR valve. Mine stuck open and it would barely idle and kept stalling when I drove back up my driveway.

Check FICM voltage. But if it was recently replaced youve more than likely got 2 bad injectors

WhaIst would the ficm voltage come up as under fuel on a code reader.... Is it considered vehicle power like I wrote up above? Because if that's the case its very low... It should be around 48

Alright guys you were right about the injectors so my question now is I can save some money if I go with a reman injector 244$ instead of a OEM 310$ is there a deference? I also heard that if one side goes the other side is likely to go soon is that true? If so I should probably replace all of them? ! ? Wtf! the s**t with these trucks never ends

Ficm voltage is ficm voltage, if it was my truck i would be darn sure that the hfcm was putting out proper fuel pressure, install a blue regulator spring, then do injectors. If you wiped injectors due to low fuel press. Then you will wipe more of 'em.
