Did you swap coils to see if the issue moves?

Ya tried that I even have new coils. Tried the diagnostic mode that fires the coil still no spark. That's why I'm thinking bad ecu.

Could also be a bad connector or wire. Do you have someone local who you can swap ECUs with to test that before you spend money to find out that isn't what it is?

No them going to try different harness before dishing out for a new ecu. Thanks for the replies.
