Stalled. Fuel Pump?

[07HOE4x4]

Update for you guys:

The thing apparently runs great...They had it fail twice but both times was off the diagnostics reader. The mechanic isn't sure what it is.

I am completely clueless on this. If anyone has suggestions please share.

I have not replaced the fuel pump but he thinks that could be a potential cause. It's at 91k miles, so should probably get done right?

Well, only if that is the problem, IMHO. If it ain't broke... then no. There are a few things I fix on the "recommend" schedule(the timing belt), but no, most of them I repair when I have to. I still wonder if you should go buy a new gas cap? Sure it is a long shot, but there is no down side if all the "mechanics" are even scratching their heads, right? I wish I had something more concrete to help you with. Keep me posted. Think about asking fiatdale. He has a gorgeous Tahoe and seems knowledge and willing to help. Good luck b2b!

Update:

Still in the shop but he knows it is NOT the fuel pump or anything with the emissions system. He's "strongly leaning" toward the engine control module. Dropping off warranty papers in an hour so they can try to work something out for me.

You guys aren't gonna believe this shit.....

And the winner is *drumroll*
A faulty ground connection for the low low price of $788!

It took over 10hr to find it and he gave me over a 50% discount all said and done. The evap issues are also handled, that was due to the purge valve. He stepped out early so I didn't get full details but I'll post back with exactly what and where next week.

Wow...

I know, they are fun to drive - but expensive to repair. Then again, nothing is cheap, right. So far, I've done a tune up, $450 with a bunch of diagnosis included and the fuel pump in July, that was $850 and that would have been more but I saved a couple hundred but buying the fuel pump first - then I got lucky because that mechanic, who I wanted to do the work was willing to put the pre-bought fuel pump in.

I fixed a-with some ac-stop leak, saved a couple hundred there and mechanics don't like to use stop leak-spent $200. Plus brakes - did my self. Shocks in the back... And still need lower ball joints in the front, but not immediately. I feel like Johnny Cash who built it one piece at a time. lol

I was just stranded out on the Mississippi river duck hunting for days with the same problem. Replaced fuel pump with no luck. Figured out it was the Fuel Pump Control Module. It can only be programmed by a dealer so I had to have it towed a second time to a dealer for the "Programming". Once that was programmed, it has been running fine since. GM decided mounting it on the frame rail below the drivers seat was a great place so it could get damaged.

Guys here's the final update:
The mechanic got the warranty company to cut a check for about 1/3 of the total cost.
Corrosion was the culprit-who would've ever guessed..... Thank you all for the help, it was greatly appreciated.

Curious- where was the corroded ground located? Do you have a picture?
