I have a 1990 Chevy full size blazer 4x4, auto, 350 c.i. that will not start. I checked ignition spark – good. It seems to not be getting fuel as it will start if I prime the TBI directly with gas. Fuel pump assembly internal to the gas tank was changed recently with new unit and the fuel filter as well. Gas tank is full. What is the most likely cause?
