Its not out of gas. I tested for spark its getting spark. i here the fuel pump when i turn the key but when i check for fuel pressure at the valve on the fuel rail it doesnt shoot out like it should it just kinda dribbles out. why is there no pressure at the fuel rail. What could the problem be? when i spray gas into the throttle body the care starts for a second then dies. i cant seem to figure it out!
My car just keeeps cranking but won't start. What could the cause be? on 1990 Chevrolet Lumina

YOUR PUMP IS RUNNING BUT NOT CREATING PRESSURE. REPL THE FUEL PUMP ASSEMBLY

so u think its the pump itself. what about the fuel pressure regulator? i was kinda hesitant on checking that beacause i didnt want to take off the upper intake if i didnt have to
