Hello,
I have been having a starting issue with my 2011 IS250. The car always starts normally after it has been sitting for a few hours, but if I drive it for as little as 10 minutes more, often than not the car will not start (No Crank either). When I try and start the car, I can hear my fuel pump running to prime the engine, and all visual gauges act normal. It will crank and start without issue if someone jumps my car. I have already changed the starter, alternator, and battery. The new alternator puts out about 13.3V (so did the original alternator). Any help would be greatly appreciated.
