That's a weak spark. I bet it's your ignition coil.

even though I’m getting the code p1389? Ignition is only 2 months old, could shorting the coolant sensor against the alt cable 12v burn a ignition coil out?

Anything is possible.

The ignition coil gets power from the auto shutdown relay just like the PCM ASD input which causes P1389. I'd bet you have low voltage after the ASD. BTW the injectors get power the same way so they might not be operating correctly as well.
BTW I may have missed this, which year is the truck ? There are some wiring differences around the ASD power between earlier and later models.
