Keeping with the current topic of hard starts, mine didn't like to start when it was hot. I'm not sure if it's related to everyone else's issue because I only ran the truck one weekend before the water pump pulley spun on the crank. It's been rebuilt and should be running in a day or two. I did notice the sensor clip was broken but I'm pretty sure it was plugged in when I took the motor out. My balance shafts were wiped out same with #4 rod bearing. Glad to know I have somewhere else to look at if the issue is still there after its running again.
