Question about 1986 Cadillac DeVille
Have you tested out the fuel pump? check for plugged fuel filter?
plugged fuel lines to the fuel rail, injection pulse at the injectors? power to the fuel pump relay? grounds needed to make certain systems work must check those also. get a wiring diagram of the fuel supply system and back trace all the wiring and see if you have power and ground and signal.
