No start - Fuel Pumps

Hey, I searched a little could not find it.

I have fuel pressure with known good relay in Supercharger relay spot external to engine bay fuse box. I don't have when removed, even with known good relay in fuel pump relay internal to fuse box.

One is for one pump, the other is for 2nd pump? Also that SC solenoid relay next to the fuel pump relay (External)?

My lightning was shutting down completely, with dash lights turning off. I fixed battery harness which was corroded and now the dash stays on, but truck won't start.

I checked spark on number one, it looks weak during daytime. Need my spark checker. Sometimes it doesn't even look like it sparks at all.

As I crank it over, sometimes it seems like it wants to go, then just stalls... No codes!

I've had my Lighting for 2 years, and apparently faced a non-starting condition 3 times. 1st time, when my F150 did not start, the problem was about fuel supply, as one fuel hose was totally broken. So I went ahead, replaced a hose with the new one (https://www.carid.com/fuel-hoses/), and it helped to start my truck. Two other times when it did not want to start the problem was caused by a dead battery.
