Have you checked/ cleaned your FPR screen that will mess with your fuel pressure more than the BB.

ok off work agian.trying to get this truck up to par agian.well changed motor harness cause it got fuel on it and i thought it may be causing this problem.and i changed out the sensor in pic(icp i think)
with another one i had and still no change.started it up yesterday and still same problem. starts runs fine for 4 or 5 sec then CEL comes on and starts idleing up and down real fast at idel.get it off idle and its not as bad and if i hold it around 1500 rpms it seems to run better and smooth out and it will idle right for awhile.if i kill it.when i restart it CEL is off till it starts doing it agian after 4or 5 sec.going to try a diff CPS today and see if it mite help.going back to a buddys that has a snapon scanner and see if it will pull any new codes.as last time all it showed was some codes with high or low fuel pressure.

much thanks guys
i'm slowly learning these things and how to work on them.now back to the rebuilding on the other motor.but i can take a little more time now
