Don't bother,you can by a new plug in with pigtail(wires) from any GM dealer.Trying to reassemble one of those would be maddening and probably wouldn't work anyway.Perhaps you could even get one from a salvage yard,then splice the wires according to color.Take care.

Its the circuit inside the ignition lock not making contact with the chip on your key. The quick fix is to close the circuit at the base of the steering column by getting a pack of resistors for 99 cents at Radio Shack. Measure the resistance from both sides of your key. Mine avg'd 4.7ohms and get that size or whatever yours measured. Remove the panels under the instrument cluster to see the steering column. You will see a thin orange cable that runs down the column and leads to an electrical junction box. The orange cable is actually a cover for 2 thin white wires. I cut the orange cable about 6 inches from the junction box and spliced 1 white wire at each end of the resistor (from the junction box side),to close the circuit, and the car started right up! Carefull removing the white plastic cover. The wire inside is thin and braided. I melted a small end at my 1st attempt. Use one resistor and it will do what the key did at the ignition lock, close the circuit.OR pull the wheel and get a new lock with keys at Buick.

1. Monitor the 5v reference, Gray wire to the Throttle Position Sensor
(TPS) with a Digital Volt Ohm Meter (DVOM) set to the MIN/MAX setting.
2. Monitor the TPS signal circuit, Blue wire with a DVOM. Voltage
should range smoothly from approximately 0.44 to 5.0 volts as the
throttle is opened.
3. Tap test the Electronic Control Module (ECM) and see if the codes come back or if the engine reacts.

You have 3 individaul coils each one sits on the ICM(ignition control module). Now if there is no power to one of the ignition coil pack youll have to replace the ignition module, It will be in your interest to replace that coil that has no power to it.
