Report Ke30 suddenly wont start in KExx Corolla Discussion Posted November 29 Hi Zoe ! Glad you got your KE-30's 3T engine running again. Connections between battery terminals & the starter motor are so important, as lots of current flows, between battery & starter motor, during cranking. As it's a circuit; the connections on the ground or chassis side, are just as important, as the battery positive (+ve) side. Cheers Banjo. We look forward to you posting some pics.
