If 4.3L engine, that is the spider fuel system, it is noted for problems. Start-up, key on engine off fuel pressure, 60--66 psi. Use a gage and check fuel pressure. That pressure is important. Once you get it running, it will run with less pressure. How long since a tune-up? Any applicable trouble codes?

Try adding some fuel injector cleaner to gas tank or if you use the low grade gas all the time every other tank put in the middle grade gas will help keep injectors clean.
