92 B18 OBD1 Teg

I pulled a plug and not getting spark
-Main relay workin, fuel pump primes, and power to the ecu.
-swapped ecu's with known good one
-checked coil with ohm per manual
-checked volts to ignition module per manual
-swapped ignition module with 3 unknown condition modules
-can hear injectors clicking with screw driver.
-new plug wires.
-new plug

Everything seems to point to junk ignition modules, but don't have any cash to throw into a new one if it's not it. Anything else I'm missing to check?
Possible to throw a scope on the signal wire from the ecu to the ignition module? What would a look for just a SAW?

Thanks

 

autozone will test the igniter and coil for free.

I just, ended up having to replace the whole dizzy on a car w/ no spark.

 

if you have an extra coil layin around throw it in to see for sure. i've seen 2 integras (1 bein my own) and a hand full of civics with the same symptoms that only needed a coil even though they all ohmed out fine according to haynes and chilton. dizzy cap not cracked and still have all its buttons and are they clean? hows your ground on the valve cover to chasis and one on tstat or tranny?

 

Oh I forgot to tell you guys that that's exactly what the problem was. I assumed that it was the ignition module cause I was under the impression that they go bad often? And both coils I had Ohmed out perfectly. :1

I borrowed a coil from Sinister's civic and it ran great until he needed it back.
Thanks for the input
