Diagnostic Procedures and Verification Confirming a faulty module requires a systematic approach to rule out other common culprits. However, installation requires care; ensuring the correct orientation and secure electrical connections is vital to prevent immediate recurrence.
GM HEI Ignition Module Wiring Connections: Inspecting Terminals and Harness Integrity
Alternatively, the vehicle may crank vigorously but refuse to start, which occurs when the module fails to trigger the ignition sequence at the correct moment. You might notice the engine cranking slower than usual, indicating the module is struggling to send a strong, consistent signal to the ignition coil.
Before condemning the module, verify that the battery voltage is stable and that all ground connections are clean and tight. This happens because the timing of the spark is no longer optimized, causing the engine to fire out of sequence.
GM HEI Ignition Module Wiring Connections Check and Diagnostic Steps
If you touch the coil body and find it is burning hot to the touch, or if you notice a burning smell emanating from the distributor, you are likely dealing with an electrical regulation issue. Using a multimeter, test the power supply to the ignition module while cranking the engine; a fluctuating or absent voltage signal points directly to the module or its wiring harness.
