1999 Chevy Blazer 6 cyl Four Wheel Drive Automatic

I have replaced the fuel filter and throttle body sensor, and had this truck running for a little while. Now its back to not running again. I started out with starting fluid threw air intake, cranked up no problem, then it wouldnt start again. Now I force fed gas threw the throttle body and it cranked over and ran again. My question is that the fuel pump or sensor?

Use a gage and check fuel pressure. Some of the national brand autostores used to loan out a fuel pressure gage. If you have the spider fuel system pressure is 60--66 psi key on engine off. Sometimes the fuel poppets need cleaning.
