Injectors, no pulse on any of them

My 94 LeSabre doesn't start. None of the injectors have a pulse. When I spray starter fluid into the intake it tries to start. Any idea what may be causing this?

Do you have a chipped key??? I think you do. Buick LeSabre 1992 to present have a VATS system. If the right resistance is not read by the system, then the vehicle will not start by shutting down the fuel ejection system. But if you spray starter fulid in the port it will start for a few seconds. Try your other key if you have one.
