Can you connect to the ecu when you have the no start issue? Does the cel also not light up?

Have you messed with the ECU connectors at all? I had a similar problem and I discovered that after replacing a wire in the connector I forgot to replace the purple retaining clip which led to the white connectors inside of it coming loose.
