Performance problems
Hey guys. Just wondering if anyone has had any engine performance issues when accelerating due to a bad fuel pump when operating the truck in hot weather. I suspected my fuel pump may be bad because I am having this problem but I'm looking for anyone else that has had a similar problem.

I just posted a day or so ago (in my thread about an exhaust leak) that I've been having a hesitation under acceleration too, and coincidentally its only when its really hot outside. It came out of nowhere last week and had never done anything like that before. Odd

reset your computer, remove the negative battery terminal for 20 minutes, this will wipe the ecm clean, after reconnecting the terminal, start and stop truck 3 times, on the 3rd time leave running for about 5 minutes so it will relearn the air fuel mix, then take it for a ride, but don't baby it, beat it. it may just need a simple recal.

I tried the reset procedure and still no luck. Unfortunately this has been an on going issue with my truck for over a year. Just seems to get a lot worse with the warmer weather. I may just have to give up on and wait till it fully breaks or take it to the dealer. Just would hate to pay the prices for them to tell me that they can't find anything wrong.

Changed out the IAT sensor the other day and I also gave the whole engine a good cleaning and still no luck with the problem. My next step might be a compression check. Still getting no check engine light telling me what's wrong so I guess I just need to keep playing the game and see if I stumble across the problem.
