Have any of you experienced the in tank fuel pump leaving you for dead?

Yup!  The fuel pump and sending unit are all one piece, at least in my 03.  Mine used to read 1/4 tank but it'd be empty.  The other problem was that it'd die, and if I let it sit a few minutes it'd start back up.  It cost me $800 to get it fixed, bit that was after 140,000 miles

My fuel pump crapped out and left me for dead/strapped to the back of a tow truck 1 time...maybe 50k miles ago? I can't remember for sure.

Yes, on two of them that I have had.  But, the fuel gauge always started to do something goofy right before the pump went haywire.  If the fuel gauge does something weird, replace the fuel pump.  I haven't a clue why they are connected but as soon as I replaced the pump the fuel gauge went back to working just fine.

When you replaced the pump, you also replaced the fuel level sending unit, which was probably why your fuel gauge was acting up.

Just a small tip works most of the time.....
If you have one of those problem fuel pump trucks, tahoes or suburban and find it cranking and not starting, if you think its a fuel pump and you have someone with you, have one person crawl under the truck at the fuel tank, with a rock, or hammer, or piece of firewood etc (your hand might work).
Pound on the bottom of the fuel tank and have the other person crank the engine at the same time...
Works quite often, just dont shut it off after it starts...

I've had to do the tank thumping trick once. Worked well. I suspect my pump failed due to repeated "hey dad the Tahoe is on empty" episodes from my daughter.

Got myself a nice 2006 Tahoe.  Man this is a nice rig.  thanks for all the comments, you helped a lot.

Very cool!! Which body style is it? Glad you got a rig you like!! We love ours.

Great choice. I love my '01 Tahoe. If you can afford it get a sealed AGM battery for it. Regular batteries even though they look sealed aren't. The battery leaks out the top and cause a lot of corrosion to the battery tray and the two window washer pumps and plastic plumbing that lie below the battery. An ounce of prevention so to speak.
