Help! I just installed new Motorcraft spark plugs (the OEM Platinum plugs it calls for) in my 97 Mark VIII and now it won't even fire when I crank it. The coils (it is a 1997 so it has coil-on-plug) all look good and seem to be firmly seated on the spark plugs and the input plugs seem OK too.
It ran fine before I changed the plugs (just changed them because they had 75k miles on them).
Thanks for any insight you can provide.
