No have gas in injectors
Thats not the most info filled post ever.
I assume you mean you have a car that doesnt start...and you have verified spark, and you pushed the schrader and no gas is in the fuel rail when cranking? ANd maybe even you sprayed some quik start or carb spray into the air filter tube then cranked it and it fired right up and ran a few seconds and stalled after the spray ran out?
If you are REASONABLY confident of all that, GMs of that era are notorious for sudden fuel pump failures. The checks should involve voltage tests, circuit verification, and current ramp testing with a scope before you go ordering a 300 dollar fuel module...
However you COULD take a large hammer...BANG FAIRLY HARD on the gas tank while someone else cranks the engine, see if it starts. If it does, this is almost conclusive proof of a fuel pump problem. DONT DRIVE IT, it may stall again soon or likely fail to restart(Especially if its a VORTEC engine!). If the banging DOESNT make it start, it still COULD be the fuel pump...but it could also be other things that require more testing...and since your info and data is nonexistant...thats all the sound advice I can give you for now without some test data and vehicle and conditions info./
