Pulled plug and cranked

fuel rail Schroeder at 32psi

not sending to cylinders,plugs dry

and before you say cops,I already changed it

Changed cps,sorry

So you aren't getting a signal to trigger the injectors to fire ? I know you said you changed the CPS , what voltage are you getting at the CPS  plug when cranking ?

This^^. Here's how:  http://cruiser54.com/?p=50

I think you have a ground issue, or some wires melted together, based on the whole bizarre issue with your brake light switch engaging your aux fan.  Might want to do a quick visual on your underhood harness, check your fuses and fusible links, and look at all the ground points.

Put a spoonful of fuel in the throttlebody after all else. Then if it doesn’t start you may have a burnt through ignition rotor. I would go after Cruiser54’s Renix maintenance first.
