pull plugs, shut off fuel, see if water comes out when cranking... that will tell you everything you need to know

How do I shut off fuel?
Pull the fuel pump fuse.

What kind of electrical things could of gotten wet which world stop it from starting
This is quite possibly the WORST advice I have ever seen in print regarding an engine that was submerged. You will ruin the engine if you crank it once it has had water internally.

well lets see...
Worst case scenario is that he's gotten water into his cylinders...agreed? (YES)
with no spark, and no fuel, and no pressure in cylinders.... whats the concern?!?!?
IF no water comes shooting out in the 1-3 seconds it takes WITH ALL THE PLUGS PULLED... THEN you can start checking other items.. Oil, electrical, timing etc... NONE of these matter if hy hydrolocked the block originally.
IF you feel you have better advice, I'd love to hear it!

dont try now, but did it crank before?
The main power of the alt could have blown your main fuse (thats a guess), but again, biggest concern is water in cylinders..
How it happened is most important to diagnosing the problem...

I ran thru some deep water too. The motor wouldn't turn over because the water traveled up the exhaust pipe into the cylinders via exhaust valves. I removed the plugs and turned over the motor thus expelling all the water out of the engine. Re install same plugs, bought new air filter and changed oil an filter . It will start up and run .Once water fill up cylinders, the motor cannot compress it so don't try cranking it over till plugs are removed

I'll add... chances of it ACTUALLY being a locked engine is low.. but without knowing more... I'm assuming the worst. again, more details needed...

So how does the car start with out spark plugs

I drove into some water I didn't know it was that deep I thought i was gonna make it I charged the water dont remember how fast I was going but then I realized I was slowing down so I stepped on the gas which did nothing then my car stopped and I saw smoke coming from my engine I got out and pushed it out and when I opened the door the water didn't rush into the car the water was lower than the car when I got it out I tried to crank it nothing I tried to give it a boost still nothing the trunk was virtually dry so I popped the hood and felt the air filter it was wet so that means water was sucked up I had like 2 inches of water in my intake manifold my coils and spark plugs were wet and oily I changed my spark plugs but not the coils yet changed the oil to and air filter and oil filter put some HEET in the tank and my battery is kinda weak so I just bought a new battery haven't tried it with the new battery yet
mujahid1994, where are you located? I do have a mechanic on hand that can diagnose the LS well. He's the only one I'd ever trust working on my cars. If you're located in new york we could head your way. It'd be great to have a LS buddy close by.
I too had driven my LS in some high water (about 1ft 4in) and never had a problem but that may be because of my aftermarket intake which sits higher than the normal stock one. The key to it is to keep the RPM's at a steady pace in order to avoid water from sucking back up into the exhaust.

i have nothing to add, but good luck pal. hope everything is ok.
The worst case scenario isn't really a scenario at all - he has water in the engine. If he cranks the engine now, he will ruin the main bearings. My step-dad drove their Jeep into some high water a few years back. Once he was towed out, he tried to start the engine with no success. Jeep was towed to a shop where it was rendered running again. Two months later, the engine completely failed and had to be replaced. Cause: Main Bearings were shot.
Rule of thumb here: Never crank your engine if it has had water in it. Any mechanic with half a brain will tell you this.
I will also add that if you aren't a mechanic and you don't know what the effect of your advice will be, it's better to not offer any.

There is nothing at all wrong with removing the plugs and "cranking" the engine with the starter. Even if the crankcase is full of water, any additional damage to the bearings will be too minor to ever notice. This is not at all the same as getting it running with the plugs in and ignoring the oil condition, and that's not what anyone here was suggesting!
If the starter won't turn it, then use a socket on the damper bolt and a long handle and see if it turns by hand. If any water comes out of the spark plug holes, the the engine was hydro-locked and some connecting rods are almost certainly bent (engine is toast). Why not try to find this out as soon as possible?
Except of course, his engine likely died BEFORE water made it's way in. Cranking after water is in will cause the damage. His best scenario will be to have it towed to a shop where the damage can be assessed.
One of the reasons insurance companies total flood vehicles is because the expense to repair exceeds the value of the vehicle. My Mom got very lucky - her Jeep was covered under warranty. And yes, I realize that driving your Jeep into a creek until the engine dies isn't a warranty issue but the dealer never asked what happened.

If it died before the water went in, then why did it die?
If it died before water went in, then there would be no water in now, so no problem.
What do you think the mechanic is going to do first when he gets it?

It doesn't. You're using the starter to turn the engine to see if water comes out of the spark plug holes. If there's water in the cylinders and the engine tries to compress it (it can't), then it will break something internal. Taking the spark plugs out prevents compression by giving the water somewhere to go.
Punctuation helps everyone...
As joegr said, You put a socket and wrench on the damper bolt. You're basically turning a bolt on the front end of the crank shaft by hand (wrench), which will hopefully turn the crankshaft and move the pistons. It turns CLOCKWISE as you're facing it, as if you're tightening the bolt. It was relatively easy for me with an 18- or 21-mm socket and an 18" breaker bar.
BILLBOATS, did you use your LS to launch a boat?
1. Probably because of an electrical failure or the inability to exhaust.
2. Sure, go with that, because water is static and doesn't seep.
3. Remove the Oil Pan, Intake and Plugs and let the engine completely dry.
Keep this in mind: Water CANNOT be compressed and when you attempt to do just that, the machine attempting to compress the water will fail, every single time.
