If like you say its getting proper fuel pressure and spark to all cylinders, and of course a good supply of air, then the engine will run. You say when it was checked there was spark and fuel pressure. My questions are is there good strong spark to all cylinders and also, was the fuel pressure to proper specs? If fuel pressure is under spec, even by a few pounds, you can have a hard/no start condition.

You mention that when you give it gas, thats usually the time it will stall. You need to see what running fuel pressure is. Also I would get a good scanner on there and watch things like the MAF sensor readings, oxygen sensor readings and make sure everthing is within specs. You need to do some troublshooting to narrow it down and go from there.
