Default 1985 corvette fuel problem

So I jump the theft deterrent and I got the corvette to turn over but it wont fire up. the fuel pump comes on and off. I change the fuel pump and fuel relay to make sure they work and still nothing. But I jump another wire on the theft deterrent and i hear the fuel pump kick on but the third time i did it the fuel pump wont come on? Whats happening?I took the fuel filter off to see if gas was coming from the tank and it is now but it is not going from the filter to injectors. The car sat for 4 years what could it be? the injectors?

The theft deterrent on your car has no effect on pump or injectors

After 4 years I would be draining all the old gas , flushing the fuel lines and replacing the filter .Once you have the correct fuel flow and pressure at the fuel rails ,ohm test the injectors to see if they are within spec

Also check for injector pulse with a noid light.
If no pulse present
