pickup wont start at times

Check battery connections are clean tight and secure. Check that the battery voltage is 12.6 volts at rest if less than that you need to have the battery charged and tested. With someone turning the ignition key to the start position when the car wont start check for power at the small wire at the starter, if so the starter may be bad.

My i280 does the same thing, let me know if you find the problem.
