Hello and welcome to Just Answer

If you're confident in the ignition coil and spark plug then I'd next inspect the wiring loom for chafe damage and corroded connections

ideally disconnect the coil connector and ECU connector and do a continuity test between the two to check the wiring resistance is only 2-3 ohms

also well worth checking that the engine loom earth connection ( a small earth wire that runs out of the loom and is secured to the engine) is clean and tight and do the same for the large battery connections and earth wires

if all of thats OK then I'd consider sending the ECU off for testing / repair
