use an ohm meter to see if you have power to the distributer you may have to jump relays ( green ones under the hood on the passenger side) you may not have the proper spark.

more info.

re-check all your ground wires to the motor and the engine harness. It could be something as easy as that. Dont kill yourself with more work than is needed.

Use a test light and check to see if you have voltage at your start signal fuse while cranking.
