for non starters the codes arnt much help at all. use your lexia and go to live data and what your looking for when cranking it over is rpm needle should be at 250 ish if not then check battery voltage/supply and starter fuel pressure should be 260ish when cranking. if not then start checling the fuel components cam and crank syncronisation If not then check sensors and wiring/fuses etc etc immobilisor/key/ecu syncronisation. if nor then start checking key fob/fuses/wiring Any of the above will stop the fuel flowing. When your in live data switch to graphs and youl be able to see if the crank is working before you order a new one

Coastline will be along shortly and no doubt he'll be able to tell you. But is your starter motor turning briskly. My C5 suffered a bout of difficult starting and eventually it was found the motor wasn't turning fast enough to build up starting fuel pressure.
