Hello and Confused

[tereptile]

Hi all, I am new to this forum and need some help. My 4,3 2000 sierra will not start after sitting without a few drops of gass or starting fluid in the throtle body. I have change the oxygen sensors up stream, temp coolant sensor, ignition control modular, took off intake manifold and rebuilt the spider injectors with all new O rings, rebuilt the fuel pressure regulator, the in line fuel fiter has been change about 8 months ago, and a tune up with wires cap and rotor same time as fuel filter. I can clearly hear the pump running when i turn the key to the on position.

Thanks in advance for an help

You need to know what the fuel pressure is. Without that it's a shot in the dark.
