95 4dr blazer doesnt start

its christmas, but my 95 chevy blazer crapped out! it was running fine all day, then after parked a while at a restaurant it wont start. the power is fine and it tries to start and starts to crank, but then it doesn start as if there is just no gas. but there is nearly half a tank left. i havent had any other problems recently, a small radiator leak, but put some stop leak in it.... does anyone know why theres no start?

I have the same problem with my Jimmy. I did a little checking and found fuel up to the rails (checked at the schrader valve), but none in the cylinders. Also have spark to the distributor, but not to the plugs.

But I haven't found the problem yet. If I do, I'll write. It might help.
