001A07504881 is serial number but I did have you guys reset it once already and did the same thing it's doing

Start by performing a master reset on the evo in the vehicle: https://fortin.ca/en/download/61931/61931.pdf

 

Once that is done, re attempt the in vehicle programming.

Best regards.

This did not work still no flashing blue light.

Does the blue led turn off when you turn ignition on or does it stay on?

---

It turns off

I would verify the Can Sw wire connection in that case

If the evo does not see any data on this wire, the blue led will not flash.

Checked can sw getting data but I also have e tharness whitxh makes connection for that and checked t harness connections all OK so now what could be problem still light off when try to program

Please meter the brown wire on the white 5 pin connector of the evo-all with the ignition on and let me know what you read for voltage.

Also when programming make sure nothing is plugged into the obd2 connector.

thank you.
