A faulty coolant temp sensor can cause a hot crank-no start with fuel and spark.

PCM thinks the engine temp is -40° and gives it WAY too much gas for a hot engine.

I like your EGR theory too. When I suspect an open EGR on something with no data I remove the valve and block the port with a piece of cardboard, gasket, beer can what have you and see if the symptoms improve.
