A pressure switch or something to lock the front brakes for when you wanna heat up the back tires?

Line lock.
I see aftermkt fuel rails. That would likely say the injs are not original.
In any case, they HAVE to be cleaned/replaced.
The fuel tank is likely toast, along with the pump, filter, and the rubber hoses.
Pull the ecm and take a look at the chip. Likely an aftermkt and may have a tune that's not so friendly with today's gas.
