GM numbers cylinders sequentially from the front.
Note that on all V motors (not inline), this means that oddly numbered cylinders are on one side and evenly numbered cylinders are on the other. One side IS a bit further forward than the other. Look closely.
An ignition module controls the timing and delivery of electrical signals to the ignition coil, which ignites the air-fuel mixture in the engine's cylinders. If the ignition module malfunctions or fails, it can lead to incorrect timing or inconsistent spark production, causing incomplete combustion. This results in engine misfires, reduced performance, increased emissions, and possible damage to other engine components. Regular diagnostics can help identify issues with the ignition module before they lead to significant problems.
Begin by removing the wiring harness from your 1998 Chevrolet Suburban ignition module. Remove the ignition module retaining screws. Reverse the process to install your new ignition module.
How do you change the ignition control module in a 1988 Chevy Silverado 5.7L
Remove the wiring harness from your 1995 Chevy Blazer ignition control module. Remove the ignition control module retaining screws. Reverse the process to install your new ignition control module.
Disconnect the battery. Remove the ignition coils. Remove the ignition control module that was under the coils, and replace it.
If on 2 cylinders, replace the coil, if on no cylinders, ignition control module, also could be crank sensor.

If you're only getting spark to two cylinders in a 1986 Olds Calais with a 3.0 engine, it could be related to the ignition module, as it controls the coil pack and can fail in a way that affects some cylinders while leaving others functional. The crankshaft position sensor is less likely to be the issue, as it typically affects all cylinders if it's malfunctioning. Double-check the wiring and connections to the ignition module and coil pack, and consider testing or replacing the ignition module if the issue persists. Additionally, ensure that there are no issues with the spark plugs or their connections.
The ignition module connects to the ignition coil via two primary wires: the positive (or power) wire and the trigger (or control) wire. The positive wire supplies power from the battery to the ignition coil, while the trigger wire sends a signal from the ignition module to the coil to initiate the ignition process. When the ignition module signals the coil to fire, it creates a magnetic field that collapses rapidly, generating a high-voltage spark at the coil's output terminal. This spark is then sent to the spark plugs to ignite the air-fuel mixture in the engine cylinders.
To change the ignition control module on a 1995 Monte Carlo Z34, first disconnect the battery to ensure safety. Then, locate the ignition control module, which is typically mounted on or near the ignition coil. Remove any wiring harness connectors and unscrew the module from its mount. Install the new module by reversing the removal process, ensuring all connections are secure before reconnecting the battery.
