Used OEM Coil Pack for the later (3-pin) 1.8 NA Mazda MX5
A common failure point. These are notoriously weak, leaving the ignition switched on without the engine running will ruin these very quickly, also a loose earth connection from the alternator can shorten their life. Does your car fire while the starter is turning and then die straight afterwards? Are there no fault codes showing? If so, the coil pack has probably died.
