Yes check fuel pressure, it sounds like pump is energizing, then shutting off, engine would only run for a few seconds on a pressurized system with pump off.
May older GM cars use oil pressure backup system to start pump if FP relay fails, is oil pressure reading good?
Also if it has a security system, that may be the cause, you would have to reset the security system.
