Hello, my name is ***** ***** I am a professional here at Justanswer. Thank you for your question and I will assist you with your concern.

Are you getting good spark at the spark plugs as well as power at the injectors on the power feed wire?

CAR FIRES AND RUNS ON SPRAY NO FUEL INJECTOR PULSE AT ALL
Expert:  Ronnie replied 8 months ago.

Okay Ron then your likely on the right track with a failing PCM (computer) . The PCM is located under the dash on the drivers side and the connector is accessed under the hood on the driver side. See the link below for its location.

THIS CAR HAS A HARNACE TO THE INJECTORS
Expert:  Ronnie replied 8 months ago.

Yes it dose, you have the power side (red wire ) and the ground switching side which is the signal wire from the PCM to the injectors.
