    The car drives forward up to 30 mph and goes into reverse and parked
    The IC Engine won't start with Triangle of death
    The OBD2 reader shows P3125 and I can't pull sub code
    The HV inverter coolant pump was new and vibrate but no movement in the reservoir. I try bleeding again and still no movement in the reservoir.

    Since the car drives with no vibration can I assume the MG2 is ok?

    What do you guys think?

    You've probably read after googling the code that your inverter is most likely the problem. Is the inverter coolant pump actually running/pumping or just vibrating? There has to be coolant movement in the reservoir or the inverter overheats. I suspect that your inverter may have died, but others will chime in.

    As I remember, there a used inverters on Ebay for a lot less than the price of a new one. I have a spare in my tool crib and would consider an offer But check Ebay, there should be one closer to the Garden State than Tucson. You should install a new coolant pump as well (don't trust a used one.)

    The pump is about 1 year old. It was pumping but now only vibrate. I try to bleed the pump but no luck yet.
    I see the inverters on Ebay for $250 - $500
    How much would you sell your inverter for?

    I assume the inverter is in working condition?
    How much is shipping to 08873?
    You take Paypal?

    James, I think I'm going to pass on selling it to you. I'm not sure it's any good. And if I sold it to you I'd be on the hook for the inverter and the shipping. A couple of hundred bucks at the very least. The point is that I can't afford to sell it and guarantee it.

    Sorry, I'd still advise finding one a bit closer to you. Sorry if this seems to be a flaky response.

    Got an used HV inverter off ebay and new inverter pump off Parts Geek. Install , bleed and now the car is working at over 300,000 miles.
    If I can just get the AC working than it would be perfect.
