Constant ground signal from the ECM, or injector could be faulty and stuck open.
A bad ingnition module, Are a bad computer.
When all fuel injectors are stuck open, this generally means that the injectors are not getting the right voltage. You will need to not only check the voltage, but make sure the injectors are receiving the right signal.
the deville is famouse for computer problems, once the car is started the brain sends a signal to the injectors to puch out an introductory supply of fuel for startup, basically this signals tells the injectors how long to stay open, perhaps the signal is telling the injectors to stay open too long or too much, good luck.
Electrical impulses from the engine control module (ECM)
This is a device that measures the pressure of the fuel that is to be delivered to the fuel injectors. This measurement is used by the engine control computer to determine how long the injectors need to be driven open to deliver a specific amount of fuel.
Your injectors stopped working because either they have failed and need to be replaced or else there is inadequate fuel pressure to open them.
