i just bought a 2000 blazer 4 door 4.3 4x4 and i cant get it to run. i am getting spark. i here the fuel pump turn on, i did a fuel pressure check and it like 49 psi. there is only 106,xxx on it and its in really good shape. i just dont know what wrong. after a spray it with starting fulid and let it sit it will start up and run fine and wont die at all. can sombody help me and give me some advice on this thanks

 

49psi is not enough pressure to open the poppet nozzles. Does the pressure bleed off at all after the pump shuts off?
