Hydrolocked?
So my truck sit for 7 months and went to start and it was cranking fine but all the sudden backlashes a little and now just clicks. I started pulling the glow plugs and have all out except 5 and 7 but still seems stuck I'm trying to pull those. No oil in de gas bottle and also was running a little rough when started but ran good when warmed up. Any thoughts? Or am I doing the right thing by pulling the glow plugs before any other diagnosis

Clicking from the area of the starter is either batteries or starter solenoid.
If you have good batteries and the starter engages then you would hear a noticeable grunt from the starter if there was something attempting to prevent the motor from turning like a hydro-lock situation.

Dang, then finish getting those glow plugs out before anything else.

I think you have a bad connection. I'd check them again.
With a voltmeter check battery volts ON TOP of the lead posts. Record reading. Then with the key held in the start position test battery voltage again ON TOP of the lead posts. Record reading again. Post the results. How much voltage drop is there? If the engine is locked up that starter should draw that voltage right down to 10 or less volts.

You can get under the truck and remove the dust cover on the transmission to get access to the flywheel. You can use a pry bar on the flywheel teeth (or a wrench on a torque converter bolt) to see if you can turn the engine both clockwise and counter clockwise.
To check for poor battery cable connections, I use a battery charger. Put the charger on the cable ends only (don't let them touch the lead battery post). Now use a voltmeter only touching the lead post. The charger will be charging at 13.8 or more volts. If the battery cables are not making connection to the battery, your voltmeter will only read the lower battery voltage (not the charging voltage). Try this on both batteries to make sure you are getting good connection to both.
Then you can try putting the charger on just the lead post (not touching the cable terminals) and see if you are getting charging voltage at the starter terminal.
This works good to verify that you are getting good clean contact with the batteries.
