Need help w/ an 87 J-body

[95z28]

I'm try to help my bro get his pos cavalier running. the car will crank and then run, but will just die after one or two seconds of running...it doesn't matter how much you rev it, it just dies...I've checked all the obvious thing (spark, fuel) and can't really think of ne thing else. The only other thing that I can think of is that the Timing Belt is gone, but if it is would it still run? Idunno...need Ideas, all input is appreciated..

thanks

The X molony ride has a timing chain so you can eleminate a broken belt or jummped a tooth, could be BAD vacuum leak, did you figue it out yet
