Please help dead yj

I woke up for work today like every other day went out to my 92 yj renegade and it started, sputtered then shut off. i then tried to restart with no luck i was annoyed so i drove my wifes car. I came home and tried again no start so heres what ive done. I checked fuel at rail and it squirts out of the valve just fine so i got fuel.
I then checked spark and yes i have spark i only checked one but it did spark.
I moved relays around and still nothing.
I then unhooked cps cuz i know they go bad like it did on my cherokee and after it was unhooked for about 5 min it sputtered but didnt start. I am at a loss guys please help, my gut says cps but i dont know, also someone said something about a cam senser on another post do i have one on the 4.0 of the 92 or no?

i dont have a way to get codes, sorry its just in my driveway. i doubled checked spark and fuel today both are there. I was wondering if maybe i dont have enough fuel pressure but i should still get something when i spray starting fluid in and i get nothing. also i checked compression and its there i think jus did the finger over the hole method.

You don't have to take to take it anywhere to get the codes, just use your key..look at ks73's post... Have a piece of paper with you and pencil to count the flashes of the CEL should be like 1 flash...pause then 2 flashes =12 etc....
