Supra not being used over the winter. Every weekend I start it up to warm it up and let it run for a bit.
Been starting fine, however yestersday I went to start it and and i turned the key it sounded like it turned over twice but didnt fire up, then the dreaded battery flat clicks started.
Jumped it and all was well, But why go flat?
Imo the battery looks a bit weedy to start a 3L engine, I just hope replacing the battrey will not reset my boost controller settings, as I didnt set it up and was told not to fiddle with it!
Would it be because its not moving, starting the engine drained the battery? All gizmos (boostcontroller, radio, led lights) appeared to be off in the cabin.
