The EIS module we have found has an issue with the part from Japan that does not have enough Sauder on a part of it, so when the temp drops below 50 degrees or less the ignition starts but all the safety features go off and the computer shuts down the vehicle.

Check Engine Light came on and took it to the mechanic who identified low compression on cylinder #3.
