Only fault code that displays is the replace liftgate fuse but that is sporadic. But that's been happening for awhile and never effected it. When the weather clears up I'm going to check all cables for cracks. All ground and power cables are tight and clean.

You can put a meter on the battery when you try to start it and see what it does to get a little more information.

Make sure you are starting out with full voltage, which means the charging system is working and there is not a drain occurring. (The battery can read full voltage but still not be good..)

Now look at the results as you turn the key to start it.
If the battery is not dropping down, there is not much of a load on it and you need to look at connections.
If it drops down bad, it is a battery or bum starter drawing too much. (rare, plan it being a battery)
You could then swap a battery or have a load test done to confirm.

Battery should not drop below 10.5vdc while engine is cranking. If it does then the battery is on its way out. Turning key on (Not engine crank position) will show any shorted loads that are ignition only circuit.

A faulty harmonic balancer can drag/lock up the crank against the block if the rubber disintegrates. Removing the belt may release the balancer enough to make it turn free.Very similar symptoms to electrical causes.

Check and see if you are losing coolant. U could pull the spark plugs and see if coolant shoots out when you turn the motor over. The motor could be hydrolocking. Pull the fuel pump fuse when u try this.
