Check the fuel pressure at the test fitting on the fuel rack while you are cranking the engine. Should be about the same as when the engine is running. If not, you may have a problem with the fuel pump relay. When the engine is being cranked, and the key is in the start position, power to the fuel pump is through the pump relay. When the oil pressure is over 5 PSI, power to the pump is through the oil pressure sensor. If you crank long enough to bring the oil pressure up, the engine can start even if the pump relay is bad or not working. However, if the fuel pressure is good while cranking, then there are many other possibilities.
