Eh9 won’t start until check engine light turns off
so my eh9 won’t start until the check engine light turns off which can sometimes take upwards of 30min depending on how long the car sits for. Once it turns off I can hear the relay pick ang the fuel pump cycle. After that it fires right up! I’ve alrasy re soldered the main relay and I’m suspecting it’s the ecm but maybe someone can confirm what I’m dealing with before I buy a new ecm? Thanks!

Before you forge into the ECU for repairs, why don't you try another known good ECU and see if the car functions differently.

You can send your ECU to Hondata for capacitor replacement. It costs $50 to have the pros do it. Or you can spend just a few $ and replace the electrolytic capacitors yourself if you are confident with a soldering iron. If you do it yourself, I'd recommend buying some good quality capacitors, like Nichicon Fine Gold.
