There is a port on the end of the driverside fuel rail. You need to use a mechanical fuel pressure gauge and check your fuel pressure there. This will tell you if the pump is weak. The pressure, key on engine off, should be at least 50 psi. Running it should be between 55 psi and 60 psi.
You can purchase these guages at Autozone or any local parts store. They are around $50. You could have a local shop check it for you but it may cost as much or more than the gauge itself.
