Usually number three is on the second CD box and only uses one side. So, to test the box, move the wiring to the unused portion of the box. If you now get spark, then tha first side is bad BUT---you don't need to buy a new CD box.

If there are two cylinders on that box, swap boxes and do the same for the one now using only one side.

switched leads to coils and moved plug wires and it started so i am positive the coil #3 is working,has to be the cd. I know the power side of # 3 is working as i just got a nice bite off that side that slowed me down for a minute. thanks once again Frank for pointing me in right direction. will post up once its all good. would be awesome to have a zero dollar fix.
