I have a 2013 civic si sedan. Earlier I had a check engine light that came on went to my computer plugged in flashpro and reflashed the car. Check engine light went away, but then I wasnt able to start my car all the lights work so its not the battery checked the grounds everything is fine. My flashpro also has the datalog and power button blinking so its not able to upload any calibration to my car. Now my car wont turn on I was wondering if anyone knows how to fix this problem? Hopefully I wont need a new ecu thanks

Do you mean the car won't turn on or the car won't start?

It wont start it cranks but doesnt turn on. The headlights on my car dont work either. Can it be a fuse burnt ecu, or flashpro? Is there a solution to this?

Also I am updated to the latest version which is 1.7.1.0

Also my flashpro links from the power button and datalog button at the same time when its plugged into the ecu.

If you turn the ignition key to the second position, does the dash light up? If you then turn the key further, does the engine crank?

It seems that a good start would be to test all the fuses, both in the engine bay fuse box and under dash fuse box.

When the key is in second postion the dashlights turn on but my navigation screen turns off and on. The engine doesn't crank anymore after i checked the fuses.

Also I cant program the ecu with my flashpro it doesnt let me press the program button it just keeps blinking when its in the ecu

There's no pint trying to diagnose the ECU where there are other problems with the electrical system.

Did you check the fuseable links in the front fuse box? Were any fuses blown? What is the battery voltage?
