All starter problems solved on the Cruiser with the coil bolt contacts cleaned, and a separate ground wire from ignitor case to the wheelwell.

Corolla prob is a software problem. Seems when the outside air temp, and the starting coolant temp are more than 45 degrees different, the ECU drops a code, and trys to relearn its conditioning. That causes problems when driving up the hill. Had to reset comp last week, and found this conditioning guide for the ECU.
