I have a 1999 Chevy s10 4.3 L V6 with about 121,000 miles on it.
The truck is in good shape but recently I was driving it and as I
would put my foot on the gas the truck seemed to decelerate almost like
it was loosing fuel supply. I pulled over and shut off the engine and let it sit for a little while. I started it up again and drove back to my house (the same problem was occurring). Now the truck wont start at all.
When I turn the key I can hear the fuel pump start to run for a few seconds then shut off which makes me think that the fuel pump is working but maybe the relay isn't working?
Check the fuel pressure with a gauge if okay, look for spark and injection pulses

Spark pulses seemed to be normal. I checked the fuel pressure at the fuel filter and that seemed to be fine, but when I checked the pressure under the hood there was none. Shortly after, I could no longer hear the pump priming when I turned the key. This makes me think that it might be my pump after all?

Not too fast -check the fuel pump relay

Yeah I checked relay. I can feel it click when the key turns
