The ignition module is under the coils. It is what the coils plug on to. To replace it removal all the coils and unplug it.

The ignition module is the flat unit that the coils are attached to and it's usually held onto the engine with from two to four mounting bolts and there are two or three connectors to disconnect. I usually leave the coil packs on it until I have removed it from the engine then I remove the coil packs from the old module and transfer them to the new module. Most of the modules sit on an aluminum plate that is a heat sink [keeps the module cool] If you have a new module you'll be able to easily see how it goes together. You're assumption that the module is bad is most likely correct. Generally if the other two coils are firing properly but the third coil is dead [and a new one has been tried] then it means that the coil driver circuit in the module has failed. Make sure the plug wires are all good as a bad plug wire can overload a coil and cause the new module to fail. Good luck, hope this helps out a bit.

Bad ignition control module act


same car as one of mine.
so you change coil packs before spark plugs?
i have the full fsm too, /.7000 pages long..... im scanning now.
you do know this is a wasted spark system so both side can fail, right.
coil pack 1.side runs 2 cylinders. not one.
both spark plugs connected to #1 coil are suspect.
they do not say how the the test is conducted (inane that)
only the useless Burn time , bull.
most times only the possible cause list is a clue to the test.

verbatim. page 4204
MONITOR CONDITIONS
When Monitored:
Engine running and battery voltage greater than 10 volts.
SET CONDITIONS
Set Condition:
If PCM detects that the secondary ignition burn time is incorrect, too short, or not present, an error is
detected. One Trip Fault. Three good trips to turn off the MIL.
POSSIBLE CAUSES
(F342) ASD OUTPUT CIRCUIT
(K19) COIL CONTROL 1 CIRCUIT OPEN
(K19) COIL CONTROL 1 CIRCUIT SHORTED TO GROUND
COIL
POWERTRAIN CONTROL MODULE (PCM)
, then a list of tests to do. in the FSM , get one.


my wild guess is the PCM ,charges the coil for DWELL time
then monitors both the low and the high signals.
if the signal is stuck low, or high this sets.
coil primary.
i think they mean coil charging fails....

Ok we changed the ignition module in our 1987 buick century, 2.5 liter and now when you start the car it just dies continuiously but once we get it started it will go but acts like it wants to die at stop...


Did you replace the crank sensor that is bolted to the back of the module? Is it possible that you got two of the plug wires switched. Or maybe 1 of the two coils is bad.

If you have a volt/ohm meter, you may want to first ohm check the resistance between the two spark plug towers on each ignition coil pack. Simply remove the spark plug wires from each coil pack and test. Both (if good) should test about the same resistance, (about 5-7 kOhms, but I don't have the exact specs handy on this particular vehicle. The reading may be higher, maybe around 7-12kOhms) but nonetheless, the reading of the 1-4 coil pack should closely match the 2-3 coil pack. If not, the new coil pack may be faulty and should be returned for a replacement.

Also, when you remove the 1-4 coil pack, take a look at the primary spade connectors (2 lugs) coming out of the ignition module. Make certain these are clean and free of rust or corrosion. If so, simply (and gently) use a finger nail file or 400 (or equivilent) sandpaper to file the corrosion off and re-attach the coil pack.

If one or both of these don't fix the problem, you may have to look at replacing the ignition module. But only do that after exhausting the other simpler and less expensive tests! :)

I hope these tips help you out or at least point you in the right direction! :)
