1992 Crown Victoria wont start

I am working on my 1992 Crown Victoria that will not start. It turns over good with a new battery. I have changed the fuel filter and plugs. I have sprayed started fluid down the intake to see if it will start and it does not do anything. I have pull the spark plug wires on each of the 8 wires and put a spark plug next to the block and turned the car over. Each plug sparked next to the block. I am unsure what to check next. Could it be the crankshaft position sensor? I am pretty much out of ideas what else to check on the car. Any help would be greatly appreciated. Thanks

sounds as if you do have spark and probably at the right time, maybe you can crack a fuel line open and see if you have pressure right at the top. cycle the key several times, do you hear the fuel pump run and shut off?
