Hello everyone, I have been experiencing some drivability issue with my truck for about 5 months now. Truck is ******d, H&S mini-max tuner, AFE cold air intake and straight piped ***. I do warm up on a cold start to 105 degrees. I hit the road, cruising till normal temps are reached 180-200. Once I get into the throttle to pass or speed up getting on the freeway, the truck fall flat on its face. No power. No CEL on the dash, only stored in the H&S mini-max tuner P087 low fuel rail pressure. Factory fuel pressures look to be ok. Funny thing is, I seem to only have this issue when its cold out, a few times in the 80 degree weather. Az, Ca, Nv summers are pretty hot so no issues. When its cold 70s and lower the truck acts up. I also have noticed the cruise control stopped working as well when the code appears. I can reset the code and sometimes it'll stay off and some times it will come right back. Extremely strange, I read and heard of people changing the entire fuel system (everything) and still having the issue. In my experience that should mean a reflash, if it persists than PCM replacement is required. :fordoval: any insite on what maybe causing it please let me know.
