To adjust the timing on a 1993 GMC Sierra 1500 with a 4.3L engine, first, ensure the engine is at operating temperature and then disconnect the timing connector (usually a single wire) to enable the base timing mode. Use a timing light to check the timing mark on the harmonic balancer in relation to the timing tab. Adjust the distributor by loosening the hold-down bolt and rotating it until the timing mark aligns with the specified degree (typically around 0° BTDC for this engine). Finally, reconnect the timing connector and recheck the timing to ensure it remains correct.
