Will it run on starting fluid? If not, we need to see if the engine has spark. This will guide us to the system that is not working.

Please go over this video which will help us see what is going on:

We should check the fuses with the key on and run the codes.

Please go over these guides so we can narrow down the problem, get back to us.

How does the engine sound when cranking? does it have compression? If you upload a short video of the engine cranking, I can tell if it is hurt or not. Also, clear the codes and then crank the engine and rerun the codes, this way we can get the most relevant ones to help avoid confusion.

Okay, so, I got it to start w the starter fluid for a split second then turns off I took off the air intake and stuff and checked the fuel rail to see if it pressure going. Cycled the key 3xs n yes squirted out some fuel... so started checking the air n everything looks normal to me I'm guessing spark it has right since I got it to start.. do you it's the fuel pump.?

That could be, does the engine continue to run as long as you are spraying fluid? If so, then it can be the fuel pump, did you clear the codes and then crank the engine over to see what codes come back, we need to narrow the problem down a little more.

P0102 - Mass Air Flow (MAF) Sensor Circuit Low Input

I would also unplug the MAF sensor to see if it starts. Check out the images (below). Please let us know what happens.
