Well, I just got done testing my fuel pressure. After letting the car sit for about half an hour, I decided to check for vacuum leaks with an unlit propane torch. Well, the Blazer wouldn't start - just kept cranking. It always starts right away. I look under the hood, and the Schrader valve had been spewing out fuel. The wiper motor was wet, and there was gas all over. What the heck? What do I do now? Is there a way to unstick the Schrader valve?

 

So, I ended up poking the valve with a little screwdriver a few times, and I guess it worked. The car started, and it doesn't seem to be leaking. It's not spraying fuel all over any more. I'll wait until everything evaporates and then see if there's any seepage.

 

I was going to suggest a tooth pick to do what you just did, until I read you had alread done did it!
