I went up a grade with a 2,000 lb trailer in 75 degree weather and got all these codes when I read them after the check engine light came on:
PO261, 264, 267, 270, 273, 276, 279, 282.
I cleared them and the truck has ran fine since.

Do you think that with all 8 showing low that it is a injector pump or FICM?
Thank you!

Check fuel pump pressure as well as the regulator.
