Does anyone have an Ignition control module handy to test? I have a 94 Grand
prix that has a miss to it. I've tested the coil packs, and they are fine.
What I am wondering, if you use an ohm meter, and test all three connections
that the coil packs sit on, do you get a reading on every one of them? If I
test the connectors that my coil packs sit on, only 2 of the 3 show any
Because each pair of ign.mod outputs are hooked directly to the output end of a
cmos pair, the resistance should be near infinite one way and very low the other
A little while ago, out of curiosity, I pulled the coils off my 3.3.
Each ign.mod pair was infinite one way and anywhere from 30 ohms to 2000 ohms the
other way, dependant on the test voltage and current produced by the VOM.
Each coil was about 11 ohms on the primary side and 7500 ohms on the secondary.
