ECU internal relay malfunction possibility
What’s up guys,
Wondering if anybody has dealt with this issue before. My ITR won’t start, check engine light isn’t working and I’m no longer hearing the clunk from the ECU when you turn the ignition on, also my diagnostic tool isn’t communicating with the ECU. Just wondering if it could be the internal relay in the ECU that went bad and if it can cause these problems.
already tested the main relay, all fuses under hood and in cabin. Thanks in advance for any feedback.

Re: ECU internal relay malfunction possibility
If there is no loud click from main relay then do not understand how it could be good.
I had an issue similar to this where P28 Hondata modded ECU was allowing the car to stall while driving and or not start at all. It turned out to be an ECU issue on the board.
Does the car stall while driving it or just wont start at all?
