    Very difficult to diagnose without being there. I am surprised the dealer has been unable to find the problem, You need to find a genuine fully certified GM technician as your mechanics seem to be fobbing you off and don't want to deal with it. Try doing a search in your local area for properly certified mechanics, or give me your area/state and i will try to find them for you. Have your mechanics tested the ignition module?.

    Try disconnecting the battery for 1 hour to see if it resets itself.

    Extracting the error codes (if any).
    You will need a note pad to write down the codes as they are displayed on the DIC (driver information centre)

    Use the 3 switches located to the right of the Driver Information
    Centre (DIC) to activate and respond to the OBD prompts on the DIC.

    ON/OFF = YES
    INFO DOWN or INFO UP = manual toggle

    Ignition ON, acknowledge any warning messages; press ON/OFF and INFO UP
    together for 2 to 3 seconds. Everything in front of you lights up for 4
    or 5 seconds, then you will see:

    Display shows "ALL?"

    Answering YES will display "ALL CODES?"
    Answering YES will run automatic test sequence and display codes, if
    any. Systems and codes will scroll faster than I am able to read them
    and write them; not to worry.
    "ALL CLEAR CODES?" will display at the end of the automatic test. If
    you are satisfied you have the information you need, answer YES to
    clear/erase all error codes.

    Answering "ALL?" with INFO DOWN will toggle systems test manually in order.
    Answering "ALL?" with INFO UP will toggle system test manually in reverse order.

    Press INFO RESET to reset DIC to "ALL?" to start again.

    Ignition OFF to exit. Give me a list of the codes displayed.

    Do you you know how to pull the error codes? I'm assuming you have the Northstar engine?

Aye, I would check or have the Ignition control module checked. Also the crankshaft position sensor imputs to the ICM. No crank signal being recieved means the control module wont send the spark out as the module has no idea where the piston position is. Surprised your local GM techs could fix this. I am a GM and ASE master certified tech who has spent the last 9 years with our local Cadillac dealership.

How can I change the fuel filter on a 1996 cadillac sedan deville

The Fuel Filter is located Under vehicle, driver side, below seating area, front of fuel tank, mounted on chassis in fuel line. The filter is fastened with pressure clips and you may need a fuel filter disconnect tool, available for about $5 at your favorite auto parts store, ask an associate before getting the tool.
Here is a pic. of the fuel filter for your vehicle

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman
