If your security light is on, then this is the problem. The security has it's own module, not in the radio. Turn the key on (don't start) let it sit for ten minutes, turn it off for five seconds and then try to start the car. This resets the security. To check the fuel pump. Find the fuel pump relay and pull it out. Put a jumper wire in the relay socket at terminals 87 and 30. 30 is power all times and 87 goes to the pump. If you have power at 30 and jump the relay socket and the pump still wont come on. Then either there is a bad wire (power or ground) or the pump is dead.

I have a 1999 Chevy Venture van I ran out of gas and now it won't start I don't hear the fuel pump running so I was wondering is there a emergency shutoff switch to the pump

There is no shut-off switch. Check the fuel pump fuse in the under hood fuse block. Also check for voltage on the fuse circuit, hot all the time. At the fuel pump connector, gray wire is voltage, solid black wire is ground. Have a helper crank it while you check for good voltage and ground at the connector.

98 chevy 1500 starts and then shuts right off have replaced fuel pump and filter ,crank sensor,cam sensor ,oil sen. coil,ign.mod and PCM

On some chevys the oil pressure sending unit closes the circuit to continue the fuel pump to run after start. In the event of a wreck ,the car stops running thus no oil pressure thus turns off power to the fuel pump .A safety to help prevent fires. When you first start the car, the computer turns on the fuel pump for about 20 seconds just enough time to start and allow the oil pressure sending unit to close the circuit to allow it to continue running. when the car car has NO oil pressure or the sending unit fails ,it will start then shut down..as many times as you try to start. replace the oil pressure sending unit and secure a good conection.

Truck runs for two seconds an shut down i changed fuel pump an filter and it still shuts down but it only stay running when i put gas down in the throttle body i had a 1996 chevy 1500 i was wondering can...

No, the fuel regulator from a 96 will not fit a 98. The 98 is a vortec and i believe the 96 is TBI. You are on the right track though, but the fuel regulator is attached to the fuel injector spider and is one unit inside the upper intake. It is relative easy to replace just takes some time.

My 99 chevy venture is not getting power to fuel pump

You probably have a bad fuel pump relay. It's in the fuse box under the hood.
