I have a 1989 Bonneville LE with a 3.8 V6 engine. I believe the ignition control module is bad from overheating. I removed the coil assembly from it and found it filled with green mush. What I need to know is the wiring diagram from the ignition coil to the ICM. And this. Should I just go a head and replace both of these units? Thanks, Ryan
I would probably go ahead and replace the components, at least with used parts as a trial.
Do you have the Delco system or the Magnavox system ? The Delco system has 3 small coils.
Testimonial: "Thanks for the reply, Steve. It must be a Delco. I didn't see Magnavox stamped on it anywhere. This is the original parts. I didn't think this question got posted earlier today, so I rewrote it here with more detail. http://www.fixya.com/cars/t18164714-coil_pack_plugs_diagram_wireorder"

Very small help:
> ,(& what is a “ballast” resistor? Is it different from a regular resistor?).
Ballast resistors are special; they have what is known as a 'positive temperature coefficient' meaning that they increase in resistance with temperature.
This provides a very hot spark to start, then a reduction in current as the resistor warms up.
This prevented points and coils from frying from unnecessarily high current.
Early electronic ignition systems still used them, I don't think any modern car has them now.
If you have a larger public library, it might be worth a look on line (if available) or a visit to search for a manual; have found some classics there.
If you find it there - copy it, then RETURN IT! :-)

found a good repair manual and followed the wiring diagram ~~~ Thank You / Jeff

Loud popping in the intake means that the unburnt gas exploding in intake.... Check cranks sensor and gear. Gear may dirty or even damage or BAD crank sensor the sensor provides reference for spark signal. So this may be your problem. Contact if you need more help. Thanks for using FIX YA

First of all, number your wires before you pull them off. Pull the wires off, unplug the module. (You need a deep well swivel socket to get to the bolts). Also, make sure your battery cable is disconnected - being close to the starter wires. It's easier to get to from under the car. Make sure you use jack stands and be extra careful. Hope this helps.

i have the same problem with my car i put a crank and cam sensor, a whole other coil pack, and an ignition control module the only thing i have left to do is put a computer in it. if you find a solution email me at [email protected]

I found my solution thanks to the instructions that came with the coil pack. The ignition control module didn't have any, but I decided to replace both parts, so this wasn't a problem. What follows is from the instructions for reference. The manufacturer is BWD and the parts are based on the Magnovox design. The difference between the Magnovox and the Delco is where the connections are for the sparkplug cables. For the Magnavox they are on both side while they are all on one side for the Delco. I don't know about the Delco, but the Magnovox has each plug connector numbered. The hookup is the same for both designs. Yellow/black goes to blade terminal 1. Green/black goes to terminal 5. The blue/black lead connects to 3. There is a solid blue wire with three connectors on it. This wire is hooked up to the remaining terminals 2,4 and 6 in any order. The wire is looped in the sense that the end connector can be placed on 4, the blade connector in the center. The two remaining connectors can be placed on the connectors they are closest to. This eliminates any slack. When the wires are connected the blade terminals are bent down 90 degrees where they are parallel with the width of the parts. This keeps them from sticking into the coating of the ICM.
