UPDATE.
I've been driving it around. However, it won't start again. Another day of 100oF weather in SC and it isn't starting. This time the gas tank is completely full, having just been filled up yesterday.
I still don't have a metal flap to protect the nozzle hole like I used to. And half the people on here say they have one, half don't so I don't know what to make of that.
I guess it's time to check fuses with fingers crossed. But the fact that it started working again and has now stopped has me confused as shit.
