I have a 98 Tahoe sport, I guess it is the Z71 package? But I have had the fuel pump replaced twice so far, then about 2 weeks ago it went out again, well I banged on the tank with a rubber hammer and it crunk back up fine. To it to the mechanic, they checked everything and said it was fine? Since it happened once, I am sure it will do it again. I gave it a full tune up couple months ago, but after that, the pump began going out. Also, when I crank it cold, sometimes it doesn't have much power, though I can hear the engine revving up, and it sounds like it should be moving alot faster than it is, rpm's go up as well. Does anyone have any ideas? I would appreciate it!
