It still starts and runs fine. I just have intermittent issues where it wont fire. I have to wait 5-10 minutes then try again.

that is "potentially" classic ignition switch issue.

how did you diagnose the ecu? you are sure it is not sparking versus no fuel?

does it start ok first thing in the morning versus multiple stops throughout the day?

did you check the fuel pump relay?
