No ,there isn't a fuel cut off switch on your vehicle . Ford vehicles have that ,not GM . Do you own a voltmeter ? Test the electrical circuit's before replacing parts . GM Fuel Pump Relay Testing
What is the fuel pressure at the rail?
Can you measure ac voltage at the injectors?
Is there a security light flashing? Do It Yourself Diagnosis and Repair
First thing I would check it the fuel pressure at the rail. You can spray some starting fluid or carb cleaner into throttle body. If it want to fire it is most likely the fuel pump. If it doesn't try to fire it is most likely ignition related. Good luck
look under the hood on the right side where your brake fluid is..There is a black box to the farest right of the brake fluid. take off the lid to this box were you will find fuses..Reach in and feel the fuses to see if any are loose.The largest fuses in the front, push down on those and then try to start it up..Take them out look at them make sure there ok if this dont work..they the one bad might need to be replaced..
Sounds like a fuel pressure problem. Check/inspect your electrical connections to the fuel pump (power & ground). Also, connect a fuel pressure gauge to the fuel line at the fuel injector rail - leave it connected so if and when you have this problem again, you will be able to determine if the cause is fuel pressure/pump.
