EliteTahoe: Did you ever find the source of your problem? My gf also has a 2000 5.3 Tahoe and it has the EXACT same issue as you describe. I'm hoping I don't have to change the fuel pump! My 1st thought was to go ahead and change the fuel filter, which i'll be doing this weekend. Any help is...
So, are there 2 types of fuel filter connections? 1 for Flex Fuel & another for non Flex Fuel? I'm going to be changing out the fuel filter on my gf's 2000 tahoe 5.3. Any help is greatly appreciated!
