No fuel cut off on them other than the anti-theft. If it is the issue you normally see a security light on the dash and the engine would start and run for a few seconds then shut off. 1997 would have fuel injection so you would want to use starting spray as any gas dumped in it would just set in the manifold. If you used a pressure gauge to check the fuel pressure at the engine and had none then it is very likely the fuel pump. You can use the prime wire to feed it voltage as a test. However GM used a dual power feed to the pump, one goes through the relay to prime the system, then once the oil pressure comes up the oil pressure switch turns the pump on. So if you can crank the engine for a few seconds it should trigger the pump. So first thing is to check the fuse that feeds the pump, it is the ECM B fuse in the under hood box. If it fails you can get a crank no start as well.
