Re: Starter problems and now flex plate

While the starters are suspect, generally hard hot starts, including slow cranking are attributed to high resistance in a circuit. While it may work on your Suburban, it's not working on your truck. Your lights aren't drawing what your starter is, especially when the alternator is not spinning. Take your known good starter off the Sub and throw it on your truck. You will likely get similar symptoms. If for nothing else, high resistance makes the rest of the charging system work harder and shorten their lives. If one size cable worked for everything, there would be no reason for these stores to carry multiple gauges.
