    Do these things step by step

    1. Check CNG conversion switch
    2. Check connections on the CNG kit for rust
    3. You'll have to install a "relay" to normalize the current flow to the CNG kit as converter's magnet has become weak and needs proper current to be kept on path. Any electrician would do it. Ask them to put relay to CNG kit (if needed)
