Hello, I own a MX5 Na 1990 kW 85. (was a gift, not rideable) the following problem: When lit only the battery light lights up nothing else and a quiet ticking can be perceived in the engine compartment. The engine does not start.(Starter also turns) the following has been done up to now: -All fuses controlled = work – A second control unit was connected by the previous owner –> the same problem The car behaves with but also without connected Is there a way to find out if the ECU is working at all? Would I look forward to a feedback. Lg Hassan
