Now you in my specialty. Take the distributor cap off, look to see if ther is a white corbon build up on the prongs sticking down inside the cap.If son, take a small screw driver and scrape it off. Check the black carbon button sticking down inside the cap, make sure when you push on it, it has some spring to it, When you push it in, it should pop right back out. Now scrape the end of the rotery button, carbon build up there also.Make sure the cap is clean on the inside before reinstalling it. I had some one prank me once by taking a pencil and drawing a line down the in side of the cap, shorting it out so my car wouldnt start. Bad prank. Now once the cap is back on, check that the wires are all tightly fitted down into the top. Make sure they are in the same order they came off, If your unsure, get out you Haines manual and it will tell you the firing order that they go in.Most Ford caps will have a 1 stamped in the cap for the number one plug. Check the coil wire to see if it is cut, if not make sure it is seated into the cap like the plug wires. Be absolutely sure the cap is not cracked down the side when you install it by pulling out on it while it is upside down, If it is cracked it will open up or break apart. Also check the plugwire are on the plug securely. I hope these suggestions help you find you problem.
