I would replace the ECU fused under the hood just to be safe. I'v seen some fuses where they looked good but there was a tiny crack in it not making the full circuit. Either that or the ground on the thermostat housing needs cleaned as maybe it got corroded when you washed the engine bay?

so the starter actually engages and spins the motor over but no spark from the dizzy?? and theres no flashing led at ANY point and time when you turn the key on?? check the fuses under the hood, and re-check your wiring(what ecu are you using??) and make sure you have no open connections or split wires that are grounding out and causing the dizzy/ecu to *** up
