They replaced the bad fuel pump with a REAL one. Back in business....AND my fuel gauge is working again!

Thanks for posting the fix on it. Glad you got it going good.
And looks like you killed 2 birds with one shot.
Now you have a fuel gauge to. Always keep it over a 1/4 tank full.
people that let there tanks get low always replace more fuel pumps.
And do not leave home without that full fuel pressure.
Good luck MT

Mine had been giving me trouble since last fall where it was hard to start. This is on a 97 GMC Suburban, 121K with the original pump. Fuel pressure was 53lbs. with key on no start. Running it would sometimes hit 54lbs. New fuel pump yesterday and it's got 60lbs. key on not running and 58lbs, running. My youngest son and I did it at home and it cost me $85 in parts.
We're leaving for Colorado on Sat. morning so I had to get it done this week.
