Mitsubishi 3000gt no start new heads cam and crank sensor new ecm timing right on good compression?

If your Mitsubishi 3000GT is not starting despite having new heads, cam, crank sensor, ECM, and correct timing with good compression, you should check the fuel delivery system. Ensure that the fuel pump is operational and that fuel is reaching the injectors. Additionally, verify that all electrical connections are secure and that there are no issues with the ignition system, such as faulty spark plugs or ignition coils. Lastly, consider scanning for any diagnostic trouble codes that might provide further insight into the issue.
