Check for leaks, also maybe you forgot to nipple some vaccum hose connections. check your 2 hoses that go to your intake piping, I had this happen to me and that was the problem.

Have you checked your AFM? If the computer is not getting a signal from the AFM, the only thing it has to run the car on is the cranking pulse (injector fire). I had a problem just like this one when I rebuilt my engine back in the day, the AFM must have taken a knock.

one way to check is to use the fuel pump jumper over on the passanger side shock tower. it's a yellow two pronged connector in a black rubber boot. jumper this connector, and you should hear the fuel pump running when you turn the key to on. If you do, try starting it then, and see what happens.
