1999 chevy 5.7 no start condition

After months of sitting it could easily be a discharged or bad battery. Sitting that long connected and without charging, the parasitic drain could kill a cell or two.

Remove it, charge it with a good charger, and take it to have load tested. If you're still running the top-post battery then it's time to get the right side-post one.

I would check the voltage at the starter. The large red wire is the positive. The starter grounds thru the engine block and frame so you wont see a big black (ground) wire going to the starter. Take the proper precautions, (put in park, emergency brake on and so on) and climb under truck with your volt meter. Have someone try to start the truck while probing the red wire and the metal frame of the starter. It sounds as if your not getting 12+ volts to the starter. I would also check the static voltage of the battery at rest and when someone is attempting to start the truck. A good battery with good connections shouldn't drop more than a couple of volts when cranking the engine. Good luck.
