Hello,  While driving down the highway, my expo just died and would not
start.  The injectors are getting fuel.  I pulled the dist. cap and
found that the contact that contacts the rotor from the coil had broken
off and fell into the bottom of the cap.  I assumed this was the
problem and replaced the cap and rotor, but it still will not start.
Just to rule them out, I also replaced the plugs and wires including
the coil wire to the cap.  I pulled one of the plugs and had and turned
it over to see if there was spark at the plug and there was not.  I am
leaning toward a possible bad coil, but need to know how to check it
first.

Thanks,

Jason
