trouble code

my 04 f350 4x4 engine light came on last week. buddy checked the codes and said a p2286 and p2287 came up. my fuel transfer pump down on the frame was making weird noises and getting really loud so i pulled it off and opened it up and it was full of crap, some of it looked like cooking grease (i guess the guy i got the truck from ran bio fuel). would the transfer pump cause these codes? i bought a new pump and fuel filters, going to install them tomorrow. ya think this will fix the codes or do i need to buy more parts?

Data log it if you have the means to do so. I'm curious to know what your ICP is reading at.

unable to data log at the moment. dont have the fancy code reader, only an old superchips programer that is vin locked to another truck so i can only use it to read and clear codes.

i replaced the fuel pump two days ago and still throwing the two codes after 15 min of driving. i can clear the codes but they come back about 20 miles down the road.

my bro in law will be here tomorrow with his code reader, it will data log.
ill post some numbers then.

data log

set up the reader and took off.....

idle icp voltage was 1.18 to 1.28
wot icp voltage varied from 1.19 to 5.09 very unsteady
let off after wot voltage dropped as low as 0.91
got back to the house and noticed that at idle the icp voltage was stuck around 5 volts and the code was thrown again. in park, at idle or a short wot rev, the icp voltage stayed 4.89 to 5.07. the injector pressure stayed around 870psi at idle not changing when the icp voltage raised from 1.28 to 5 volts. injector pressure did raised as high as 3200psi at wot.

the truck runs as it always did. have not noticed any change in the motor since the codes started popping up. still getting p2286 and p2287 on second start after clearing codes.
