Shut off while driving, where is the Fuel Relay located?

Hello, is this vehicle still under warranty? You have very low mileage. This vehicle uses a direct injection fuel system which has a fuel pump in the tank and then a high pressure mechanical fuel pump that's driven off of a camshaft and the pressures for these systems can be up to 1,500-2,000 PSI, so do not try taking apart any of the steel lines going to the fuel rail, you can be seriously injured.
The low-pressure pump is powered by the PGM-FI Main Relay 2, I'll post a diagram for it, there will be a plastic or rubber fuel line coming into the high-pressure fuel pump, and that's where you would take a fuel pressure reading to check if the pump in the tank is working.
But the first thing to do is go through and check all the fuses, there are 2 PGM-FI relays that power up many components, along with the low-pressure pump and ECM. So, see if any fuses are blown first, write down which ones are if any, and we can help you from there to figure out what's going on. But if you still have a warranty, I recommend taking it in and letting the dealership repair it.
The 3rd diagram is of the high-pressure fuel and fuel rail, do not unbolt these lines, they are usually a onetime use as well. It takes a trained technician to work on these high-pressure systems.
You should start with the basics when it comes to a crank no start situation, it's faster to check for ignition spark. There is a guide below for doing that, if you're missing spark you could be dealing with a failed crankshaft position sensor or another issue. Does the Check Engine light come on while the vehicle is cranking over?
