hi all,

2013 screw 6.2

just yesterday i started having this issue when going to start the truck. it happened about 6 times today. truck eventually starts and runs fine after the grinding/hesitation.

i recently had an engine fire but everything was replaced by mechanic.
-alternator
-battery
-battery to alternator wire harness and belt.
- a few other things but nothing that would cause this type of issue.

i also just replaced the spark plugs with new wires and boots

planning on bringing it back to the same mechanic but could this just be my starter going bad?

ive attached a link to video of it happening ( 3 different clips all within about a 1/2 hour )

thanks in advance.
