the original problem was loss of power at cruise...engine stalled had to be towed by a friend..Cry
Plenty of fuel no problem there..
 
got it home put a meter on it 12 v at coil + with ign in run..no spark when cranking and plug against the block....
swapped coil from my 2A and it started right up no problem!!! ok got new coil from AZ...it ran for a few days and then the same problem no spark..
here is my mistake  I think..please help out
The new coil, I never knew there was a "external" or "no external" resisitor, was marked external resistor only...I did not pay too much attention...my 2A coil is marked no external resistor...
I do not have an in line resisitor on my 75 CJ5 with a 4.2 I6, nor does it look like I ever had one in line...
So did I fry my ignition module using the wrong coil?   I put my 2A coil back in the CJ5 but no joy no spark...all wiring looks good..ground on the Ign module was a tad rusty but it ran before...so cleaned up the ground and will be heading out tomorrow for a new coil and ign module..
what do you guys think?  am I missing something?
