Car won't start after overheating
I have a 2010 IS250, I was driving and heard a clicking sound, the temp gauge went all the way left to the cold side and the car started to overheat. I pulled off and it died, I wasn't in a good spot so started it again and got it to a better spot and it died and wouldn't start again. I opened the hood and there was coolant everywhere, I towed it home, read the codes and got:
P0117(Engine coolant temp sensor-low input)
P2017(Intake manifold air control actuator position sensor/switch, bank 1-circuit high
So I replaced the coolant temp sensor and nothing, it cranked but won't start and the code didn't go away. Towed it to a shop and he said there was no voltage to the direct injection high pressure fuel pump, it was bad. That didn't sound right so I took it to another shop and they said the water pump was bad. I changed that out today but it still won't start and the two codes remain. I am stumped, did the ecm shut off power to the fuel pump when it started to overheat and why did that code not go away when I replaced the coolant sensor. Any help would be appreciated.
