my nightmere (msd)

Did it run good for the minute that it ran after you converted it? If so the wiring was probably right. You may have just lost power somewhere leading to the balast resistor. Have you checked to make sure you have power at the ballast resistor with a test light or meter? If you do have power there the only other possibilities are a possible bad pickup in the distributor which you can check by doing an ohm test with an ohm meter. Should have about 600-700 ohms across the leads or maybe you got a defective MSD box.

BTW: You are positive it don't have spark aren't you? A lack of fuel can cause a situation similiar to this also. (i.e. A clogged fuel filter) Have you had someone crank it over while you checked for spark under the hood to verify it has no spark?
