My 01 tahoe will start and then chug out and die. I changed the fuel filter. While filter was off I turned over ignition and gas pressure was explosive. Under the hood I replaced fuel pressure gauge. This helped some. Then I switched my starter and ignition relays and it helped more. But still stalling out. What else could it be?

anti theft system? Is the light blinking on your instrument cluster?
I am not understanding what fuel pressure gauge you replaced under the hood. I am assuming you mean the fuel pressure regulator or the fuel pressure sensor, correct? I would attach a manual fuel pressure gauge at the rail and monitor what it does during the start and attempt to run cycle.
By the way, I recommend introducing yourself first in the Newbie section.

Welcome Eddie, you may see this suggestion many times bc it is so common and causes all kinds of problems. Check your battery cables top to bottom especially the ground cable at both ends. They get corroded over the years.
