When I turn the switch to on I get a "gauge" light along with the check engine light with the engine not running. The engine does not run it does however cranks. I checked the pressure on the fuel line and it was low. I changed the fuel filter. The fuel pump does not turn on. I checked the fuel pump fuse and relay and they seem to be working good. I checked the voltage comming from the ECM and it is not there. I suspect that it is a oil pressure switch. Question is this a good assumption and where is the oil pressure switch located at in this vehicle? Second what else could cause this problem? Thanks.

Do you have a VATs in your car? Take a look at this write up and see if it helps.

Thanks for the post. The engine cranks over and there is no security light. The problem is that the engine is not getting any fuel. Does anyone know what troubleshooting steps I should take to narrow it to a bad part?

If no fuel that leaves a bad pump, blown fuse, bad relay. Check the fuse, if good, test the relay. https://www.gmforum.com/t279561/ If good, check the fuel pump.
