non-injecting injectors

I have a '95 Sonoma that has just up and died. I have plenty of spark and plenty of fuel pressure to the fuel rail. But it seems like my injectors aren't working. The 2.2 turns over but it won't run or even sputter. I can't believe that all of my injectors went bad all at once. Can anyone help? Thanks

How did you check the fuel pressure? Where are you testing spark at?

I put a T valve inline after the filter. (42 psi) I checked the spark by pulling out the plugs and watching. I found out that I lost compression in the #2 cylinder this weekend so I may need to do some surgery. Thanks
