I'd look at the crankshaft position sensor located in the frt cover under the crank. I've also seen the wires break in the insulation a few inches back from the connector. May sound basic but check all your fuses. A blown pcm or inj fuse will bite you in the ass.

thats the first thing i did was check the fuse's ..it has spark and fuel pressure.... so i hook the scanner up and no codes where present, and i went into the data stream and thats where i saw no ijector pulse but i can pulse them in the injector balance test

When your cranking the engine does it show RPM on the scanner?

If it was security it would start and then stall. Did you figure it out or still checking?

You need to see if there is an aftermarket alarm system on your vehicle. As far as I know, the system is not designed to have the horn go off for no reason. Some of the aftermarket alarm system are designed to cut off fuel.
