Stalling problem
 

So, I have a 1994 ford ranger 2.3L xl 4speed Manuel. I've been having a problem with my Engine stalling out. So it was running fine went to go to pick my fiance up from work, wouldn't crank. It would try and start up, rev up then stall, Replaced the Idle air control valve and it sounds better trying to crank but does the same thing. Cranks over then immediately stalls out. Other than the IAC valve I'm clueless on what to do. I really don't want to pour money into it for things not to work. Any help would be greatly appreciated.
