with your problem It would be most likely the fuel pressure is too low. with no failure codes DTC's this is a first step in troubleshooting ..follow the testing proceedure listed in these forums for your vehicle you must have 53-62 psi ...these vehicles require that the fuel level be kept at above 1/4 tank...operating below 1/4 the fuel pump burns out ...

the reason to follow the testing proceedure is to determine what componet in the fuel system is the problem..If the pump is defective , replace the fuel filter,and relay...

If you give the bottom of the fuel tank a hit to shock it it , may work for a short time ,,if so this is 95% chance the pump is shot..
