318 hard start when hot

Bewy said
The first think to check is the battery. 12.3 is discharged. Charge up the battery, either with a charger or idling the engine, then let sit for a few hours to dissipate the surface charge. Good battery should measure 12.6-7 v. If lower, I would get a new battery.

Battery was at 12.6 until trying to start it hot. That half a crank to full crank brought it down to 12.3. Is a new battery, just bought it pretty recently. I wouldn't consider 12.3 discharged though, a bit low, but not discharged until under 12v. I can still start my chevy with a 454 on that 12.3 like it's nothing.

As far as the suggestions go, I'll be checking out the coil and checking all my grounds today. Reading into the dakota starter switch, seems pretty quick and easy, so I'll be buying one of them here soon as well.

Appreciate the advice so far guys, thank you.
