Hello Mates,

I have a Corvette C7 2014. It was running very well and after we changed the cylinder heads the engine won't start.

I got those error codes with HPTuners:
0x541: B1517 - Battery Voltage (Pending, Current, Old, History)
0x541: B3205 - Driver Window Motor (Pending, Current, Old)
0x541: B3210 - Passenger Window Motor (Pending, Current, Old)
0x543: U0422 - Invalid Data Received From Body Control Module (SES, Pending, Current, Old, History)
0x543: U042B - Invalid Data Received from Chassis Control Module A (Pending, Old, History)
0x552: B127E - Front Video Display Output Signal (Current, History)
0x7E8: P0107 - Manifold Absolute Pressure/BARO Sensor Low (Permanent)
0x7E8: P0192 - Fuel Rail Pressure Sensor A Circuit Low (Permanent)
0x7E8: P127C - Fuel Rail Pressure Sensor 2 Circuit Low Voltage (Permanent)
0x7E8: P16A1 - Sensor Communication Circuit High Voltage (Permanent)

I changed Today the battery with the same issue. Starter is working but there is no spark.

Please I need your support.

 

On my engine, there are some important ground points at the back of the cylinder head. Are those in place and making good contact?

 

as Grubinski mentioned, you left something unconnected. Ground or other.

 

^^^ Agree; In for the fix
