99 Tahoe - Trouble Accelerating / Hesitation

--------------------------------------------------------------------------------
1999 tahoe
5.7 motor
156000 mile

this is what i did to fix


my 99 4WD Tahoe has been giving me problems
accelerating when I give it a heavy foot. When I hit the gas down it loses acceleration.
almost like it being starved for gas. When I hit the gas the engines just bogs down, begins to hesitate, and will not accelerate.

some one said it was distributor cap. guess what thats not it.

i have seen alot of threads on here about the same problem

it was the fuel pump i drive about thirty miles one way and about half way home it was actting up.

i have seen alot about not using airtex fuel pumps and the guy that had this before me used a airtex fuel pump imaign that .

so what i could figure out is that about half way home the pump would start getting hot and start lossing presure

and when you shut the key off it was like resetting it but what it is doing is repressurizing the system to 62 psi then slowly loss pressure again.

i change the fuel pump with the delphi fuel pump and now everything works great


just thought i would post this because i have seen alot of these threads

Appreciate the heads up post. Thanks.
