Likely, if it was an ignition failure, you would have some type of code. Check for (listen for) fuel prime during key-on. If you hear the fuel pump whine during this initial key-on, you know the pump can at least function. But you need to know if fuel is present at the engine. You should also check for spark at the spark plug boots.
Let us know what you find.
