    Shouldn't even take that many steps ... key fob insert, step on brake, push button one time, READY.

    Are the brake lights in back glowing when you step on the brake?

    Orange safety plug is inserted correctly and the fuse inside of that is good?

    I second the safety plug. Flip up and then push downward to lock. Many people miss the push down to lock part

    Just a WAG. Blown AM2 fuse caused by a shorted inverter coolant pump.

    C'mon man you have been here a long time you know we need the codes. Of course there readable you just need a techstream capable OBD reader.

    Good 12 volt won't start usually in hi voltage ground fault lock out. Disconnect the main 12 volt lead by unclicking its white connector at the battery positive terminal black fuse assy and wait 30 seconds and plug it back in.

    if not that you need codes pulled.

    Please expand I am unfamiliar with WAG
    Just so I am sure the AM2 fuse is the one encased in the orange safety plug

    FYI
    A couple of thoughts ….. I have seen another thread where Gen 2 has the following conditions/issues..... failed coolant pump....No MFD..

    You are probably correct on following
    Need access to techstream OBD2
    However SG2 has yet to fail me
