2019 off-road won't start

Posting this here hoping to get some advice.

Long story short, my buddy and I were trying to fix some aftermarket electrical issues in the relay box under the hood. We checked a few fuses, etc, but no changes were made to the system. I pull the truck out of the garage into the driveway for some more space. Turned it off, checked a few more fuses and tried to start the engine again, but it won't start.

The engine is trying to turn over but it won't start. Truck has gas, battery is at 12.5, everything is plugged in, locked down, clean, etc etc.

Anyone seen anything like this before? I feel like we've checked everything we can from my driveway... any advice or input is greatly appreciated!

 

What are the aftermarket electrical issues?

 

This…we need to know what you’re trying to fix.

 

None of the led lights on the top rack of the truck work. Front light bar, 4 side leds and 2 leds in rear.

We were just checking the fuses for that and looking at the wires around the truck.

 

My buddy seems to think the problem is the fuel pump after he listened to me try to start it. Is that a possiblity?

Seems strange after I backed it out of the garage, but I don't know.

 

We need more information. You probably popped a fuse somewhere doing work or from how the lights were added initially. Where are they wired to?

 

You say its trying to turn over but won't start.
Is it turning over or not?

 

Yes, it's turning over.

The relay box is set up above the fuse box by the engine. I completely unhooked the relay box, so that mod is no longer impacting anything.

 

Also, the "smart entry & start system check" warning light came on. I'll start to look into that.
