I posted a couple of times the CEL that lit up.
I also already cleaned the MAF sensor with a electronics parts cleaner from radioshack.
I own my own scanner and the only code I have is
"P0171 System Too Lean (Bank 1)"
and my the pressure at the fuel rail is 30PSI, Spec is 50-60.
I do not mean any disrespect, but it just seems like people aren't reading my post thoroughly. Just shouting out answers.

The fuel pump is located in the tank, so you'll have to drop the tank to replace it, not the worst job in the world....not the quickest either.
Here's a "How To" write up....

But before I'd commit to a new pump, have the codes pulled, any auto parts store can do it.

Thank you for the link, I had been checking that post out.
I really hope that the fuel pump is the problem, I will post an update in a couple of days when it arrives and I install it.
If not, hopefully I can remove it and return it without signs of install.

It might seem we are just shouting out answers, but the answer isn't always just as simple as "yeah it's the pump". We are just trying to suggest all the possibilities.
Hopefully the pump replacement will fix your problem. Just remember to reset the CEL before any test drives. You need a clear code memory to monitor since stored codes aren't dated. That way if any codes pop up you will know they are new. Good Luck and keep us posted.

Sorry I didn't say it to be rude but information that was posted was being asked.
I got home today and now I have "P0303 cylinder 3 misfire"
I do not know how long ago that came on, last time I checked the CEL was about a week ago.
Is there any type of warranty for that code? Such as certain years or miles?

A tip for any DIY'ers in the future,
If you tackle the job of replacing the fuel pump, dont try to remove the exhaust, just take the 2 nuts off after the cat and move it to the SIDE. I spent an hour trying to figure it out and finally realized that I could have moved it to the side after removing the hangers. ( to remove hangers, grease them up and they will slide right out!)
Fuel pump was $315 with 1 year warranty from autozone.
