I have a '96 4 door blazer. I've had the fuel pump in it for about 5 years now since it was last replaced. Now what issue im having is It starts up fine. you can rev it up fine in park and no issues what so ever. when I go to pull out and give it some gas it shutters/ wants to stall When i give it more gas. if i feather it for a few seconds it'll be fine. I have to feather it to get it moving. Once i get it moving after that shutter its perfectly fine. It does this every morning when i leave for work and when i leave work. Fuel pump maybe going? I've replaced the iacv and the EGR valve. No luck. I did a tune up beginning of the year and it still goes on after new cap/rotor/plugs/wires all ac delco. I have an airtex fuel pump in there now.

Thanks!
