I have a 97 Chevrolet 1500 with 4.3 vortec rwd truck

My trucks spiders aren't getting any gas running through them but it is getting up to them, When I push the valve gas shoots out

Stuff I've done:
Tried 3 sending units
Tried switching the spiders
Fuel filter is good
Tried another computer module

Poured gas into the throttle body and it starts for a couple seconds then it shuts off again.

Found out the problem is the gas isn't shooting out of the spiders but its getting up to it.

Anyone know what could be stopping them from going through to the spiders?
Do you

Use a gage and check proper fuel pressure, key on engine off, that start-up fuel pressure can be critical, 60--66 psi. Once the engine starts, it very well may run fine with less fuel pressure.
