I have a 94 lancer glxi (4g92a engine) na bigla na lang di na umistart , ok naman po yung starter dahil it cranks the engine normally para umistart kaya lang di tumutuloy. I have inspected kung merong spark sa high tension wires leading to the spark plug and there was none., so a mechanic tried to replace the ignition coil thinking na yun ang sira pero it still would not start, so ibinalik na lang uli yung luma.

Another mechanic told me na baka ecu ang defective but the check engine lights goes on after turning on the key and goes off after 5 seconds (which is an indicator na ok ang ecu, correct me po if I'm wrong) , so medyo hessitant ako na bumili agad ng ecu dahil medyo mahal din.

Ano pa ba ang pwedeng pagmulan ng sira nito aside from the ecu and ignition coil? TIA
