Loss of power

I've got a 2003 F350 6.0L powerstroke and my truck seems to have lost power. I read the codes, and this is what I'm getting:

P0284 Cylinder 8 contribution/balance fault
P2285 Injector control pressure sensor circuit low
P2290 Injector control pressure too low

Somebody told me that the problem is the fuel pressure regulator however I'm not convinced by this answer. I'm wondering if this is, in fact, the problem or if it's something else. If it is the problem, where is the fuel pressure sensor located on the engine? And what the cost would be.

Thank you.

The IPR is not a bad inital call since your codes are fuel pressure related. This is where a good tech will the test to verify that you indeed have low fuel pressure. By looking at live data to see what pressure the computer is seeing and then manually testing the fuel pressure to see if that is the actual fuel pressure that you are getting.

The #8 injector code could be because of the low pressure as well as the cause of the low pressure. Blown o-rings or tip on thaat injector could cause an overall drop in sysstem pressure. I would have expected more injector codes but if #8 was the only one polled enough times by the PCM to set a code before the key was turned off. I guess it would be the only one shown.

NO POWER!!!!

I've got a 2003 F350 6.0L powerstroke and my truck seems to have lost power. I read the codes, and this is what I'm getting:

P0284 Cylinder 8 contribution/balance fault
P2285 Injector control pressure sensor circuit low

Thank you.

P.S. I recheck and i am still getting the code P2285 which is the injector pressure sensor control. But someone was telling me it could be something else and i would like to know where this sensor is located. Someone told me it is on the front left side of the engine under the air to air pipe. But someone else also says that it is the right bank of the engine behind the turbo. If someone can tell me where it is or even send me a picture of it would be very appreciated. Thanks
