    This is a 2007, with a 42RLE.
    A start circuit was SO simple but MICAHI has replaced KISS. GD millennials, they could ruin a "good" dream.
    RANT OVER

    you claim "replace safety neutral' is this the TRS Transmission range sensor?
    Start with a SCAN using a good scanner as there may be some codes that may help (ie P0706).
    The wiring is STOCK no added BS - remote, added alarm, etc.
    Might want to swap relay with a like and less used relay - horn,?

    There is a known issue with TIPM time permitting I will get details while I await the answers to above. Scan and modifications, and relay swap/check.

    That aftermarket BS would be a focus. BUT you still need to scan.

    Are you comfortable with wiring diagrams a scanner and a DVOM ?
    We could get you a wiring diagram of start circuit to aid troubleshooting.
