GMC C1500 ENGINE PROBLEM

2000 GMC C1500 • 110,000 miles

Engine starts immediately but stops running within 2-3 seconds. Fuel pump is running and reads 60 PSI at shrader valve, Pressure regulator replaced and new fuel filter installed. Direct injection of gas supply into intake plenum keeps engine running. What is the problem causing the system to shut down?

When it stalls is the fuel pressure still 60?
