The FSM has all the diagrams you'd ever need.

A motor needs 3 things to start:
-proper air
-proper fuel
-proper spark
Is there spark at the spark plugs? Are the injectors spraying?

. . . . . Plugs back in order. . . . . Ground wire to dist hooked up?? Check the thermo stat housing did you hook up the right wire to correct sensor. . . . . My dumb *** moment two days of bitching tottal loss ! Are the fuel hoses correct? I had mine on backwords 
take your time one wire makes the car run or not run in this case. . . . . Always take a mental note on how the car runs and what part goes where before takeing it apart. . . . . . Think everyone here has had that dumbass moment missed connection or hose in the wrong place. Just go threw the car again and repeat

Oh and timeing well if you moved the dist yea going to have to time it. . . . If you didn't touch it your fine really sounds like a wrong wire or a wire not hooked up. . . . . The three I found that will kill the engine are black wire on bottom of dist going to ground. . . Square plug in the 79 should have 2 on the themostat housing if they are backwords wount run. . . Ones a temp sensor not sure what the other is. And lastly the plug for the dist itself. . . Other than that car will run shitty of course long as you have injectors plugged in and the mass air plugged in car should kick over or at least try. . . . . .
