  1. Maybe considering there is no fuel pressure sensor for the computer to read from the Mass Air Flow calculations and thresholds set from the factory may not be met if there is no fuel pressure. If the owner can only get to about 2000 to 2500 rpm and the computer won't let the truck shift until the rpms are lowered which uses less fuel which is exactly what my truck did with the MAF code and probably in the future as the problem gets worse some o2 sensor codes saying the fuel is too lean. Moral of the story my opinion check the fuel pressure or get it checked and go from there. The codes thrown aren't always the problem.
  2. Fuel pressure should be around 60 idling. Get someone to rapidly accelerate the truck in other words put the hammer down pressure should drop slightly then return to 55 or 60 still at high idle. Sent from my Pixel 3 XL using Tapatalk
  3. Check your fuel pressure sounds like maybe fuel pump starting to act up like my 2005 GMC Sierra 1500. Same exact symptoms. Fuel pressure tester is around 30 or 40 bucks at harbor freight definitely would look into it. Sent from my Pixel 3 XL using Tapatalk
  4. Completely guessing here but have you checked the fuel pressure? While my pump was going out i got o2 sensor codes. Also cleaning the grounds are never a bad idea. 2 on the back of the block with the right wobble socket and wrench all you have to remove is the vortec cover on the motor. 2 under the truck about even with the driver door on the frame. 2 on the same side and frame rail but about under the headlight then one running from the battery to the side of the block. Like i said not sure just wanted to throw the possibility out there Sent from my Pixel 3 XL using Tapatalk
  5. Sounds like the starting symptoms of a fuel pump going out. I ran mine for a year doing the same thing. I didn't run it until it quit but that's when my trouble started. May not be the same situation but just a possibility. Sent from my Pixel 3 XL using Tapatalk
  6. All of these codes have one thing in common: fuel. I had the exact same problem on my 2005 gmc Sierra 1500 and it took me about a year to figure out that the fuel pump wasn't getting the correct psi. Very frustrating especially after cleaning grounds, new plugs wires and coils, a gas pedal sensor and a throttle position sensor and still no change. Fuel pump is the problem in my opinion but if you want to make sure use a fuel pressure tester and test the psi on the fuel rail. It should be around 60 idling. It should drop during acceleration briefly then come back to 60. Mine was staying at 30 regardless. Best bet is get a fuel pump make sure it is the correct pump for your bed size and it should resume normal operation. Sent from my Pixel 3 XL using Tapatalk
  7. I did exactly the steps you did as well as install a throttle position sensor. It didn't go away until i installed a fuel pump Sent from my Pixel 3 XL using Tapatalk
  8. My truck was doing the exact same thing and like you i was pulling my hair out too. A fuel pump was the answer to my problems. If you are having o2 sensor codes on your scanner install them as well. If you want to varify the problem buy a fuel pressure tester from somewhere like harbor freight and see if your pressure ever goes above 30. My truck still pumped fuel and if i was easy on it it was drivable but still had the loss of power with no explanation. Make sure you order the right fuel pump as well according to bed size. This should solve your problem so your hair will be safe lol Sent from my Pixel 3 XL using Tapatalk

  10. Get one of those quick splices, a fuse holder and a test light and see which wire makes the test light come on. Splice into it and find a frame ground or ground to the battery Sent from my Pixel 3 XL using Tapatalk
  11. Im not 100% sure if the wiring is the same but more than likely it is and should bolt right up Sent from my Pixel 3 XL using Tapatalk
  12. From the picture i googled looks like youll have to spin it left Sent from my Pixel 3 XL using Tapatalk
  13. The blower motor is not hard to change at all. Removing the dash is not required. Remove the black plastic cover in the passenger side floor board under the dash. 3 7mm head bolts. Unplug wiring harness from blower motor and im not for sure which way to turn it but you have to twist the whole motor assembly to remove. Look at the base of the plastic motor assembly and turn towards the big gap then the motor will slide right out. Sent from my Pixel 3 XL using Tapatalk
  14. That's the same thing mine was doing i put that pump in and it solved the problem Sent from my Pixel 3 XL using Tapatalk
  15. Mine used to do that it just went away after a few times Sent from my Pixel 3 XL using Tapatalk
