At first i thought it was the alternator so i replaced it, then it shut off as soon as I pulled out of my driveway. Then I thought it was the battery, so I used my jump starter and went to get my kid from school, and it shut off again. So, I bought a new battery, put it in and when I started it up it idled for a few seconds and stalls out, so I towed it home. I’ve replaced the alternator, battery, spark plugs, ignition coils, battery terminals, checked fuses, replaced the valve cover gasket, cleaned the throttle body and it still does the same thing. I can start it up and it’ll idle for a few seconds, and it’ll start sputtering even if I give it gas to try and keep it on it just shuts off.

Yep, this happens when the fuel pump is going out, but to be sure we can check the fuel pressure by following this guide. You can rent a fuel pressure gauge from the auto parts store for cheap.

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Fuel Pressure (At Idle) 304-343 kPa (3.1-3.5 kgf/sq.cm, 44-50 psi)

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
