my 78 f150 (400m) isnt getting any spark. it will start then stop right away (wont stay running) and then i can crank it and it will just crank, but wont start. i pulled the first spark plug wire to test for spark and it started right up and ran, but eventually i got no spark after starting it a few times. obviously its ignition related but were do i start. its got a msd ignition system on it (dist., coil, module), so any help would be appreciated.

Check out this test.

This will allow you to test the MSD ignition to see if it's working or not.
