poor starting

hi my 2012 dclb 4.0 has begun takeing more cranks to start latley probably 80%of the time hot or cold. all seems fine to me batt has 12 volts also around the same time it seems to kick off at the pump early and can be a pain to top off . i dont know if the two are in some way relatedi have driven away from a full service pump with 3/4 of a tank due to this any advice appreciated thanx.

 

Vapor recovery valve or charcoal filter may be the cause for the pump shutting off before its full. I would start by making sure the vent line is ok.

Look all the way at the bottom of this, hope this helps.
