Thanks Maurice. Checked the battery both voltage and amperage. Voltage stays well north of 12V even when key is turned to start. Low amperage draw when key is turned to run and nothing additional at start position. Look like something else is either preventing the start circuit to complete or it is otherwise open somewhere.

So, been having some odd things happened with wondering idle (unplug/re-plug ECU and it resolves) and most recently, dying on idle until the engine warms up quite a bit (idles around 1300 RPM normally). Been sorting these mechanically and now having a more serious problem. Tried to fire up the car today and nothing. When I turn the key to "on", I can hear the relay(s) in the TRW multi-function relay unit click but the fuel pump does not come on and prime. Then, when I turn the ignition to "start" I can hear the additional relay(s) in the MFRU click but no starter turn over. I have checked the fuses, battery voltage, and have power to all other dash, lights, gauges, etc. 2.0 Duratec in a 2012 R400 SV. Any suggestions on where to start my troubleshooting?
