    Check for spark and check the fuel pressure.

    No or low fuel pressure ,vehicle wont start.
    Also the injector poppets can stick closed on these..causing a no start...

    You need to determine whats missing,spark and/or fuel....If you have spark and good fuel pressure,you need to check for injector pulse....

    Fuel pressure is between 55 and 62 psi....any lower and it wont start...

    No spark ,can be issues with ignition module,theft system....etc...what sensor did you replace?Cam sensor is in the distributor ,also has a crankshaft sensor....
    Also check all the fuses.......

    And the connectors on the fuel pump modules are known for failure...the new fuel pump/modules come with updated connectors

    Autozone rents fuel pressure gauges and noid light kits...

    Just a bunch of thoughts
