SOURCE: 1994 gmc sierra 1500 timing

The timing may be adjusted only on those that are equipped with a conventional distributor ignition. if equipped with the distributorless Electronic Ignition (EI) system, the control module set timing and makes all necessary spark changes. On these systems, the cranksshaft position sensor is mounted in a fixed position, therefore not allowing for adjustment. The HVS system found on some 1995-97 vehicles is also not adjustable.

Ichanged the head on my 91 geo storm 1.6 dohc and now it won't start


Double check crankshaft timing mark, on your lower timing cover has some timing marks - crankshaft should be on the 0 mark. Camshaft timing marks--intake camshaft mark set at 3 o'clock and exhaust camshaft mark set a 9 o'clock. These timing marks are critical for motor to run and start correctly. These timings marks can move while trying to install the timing belt. After, you confirm or reset timing and belt, you can confirm timing is correct by rotating the crankshaft twice. Your timing marks should be on right on timing marks discussed at the top of the page. If timing marks are off, start over with timing process.

How do you fix timing on 96 nissan sentra


For adjusting the ignition timing, you need a timing light.
Attach the spark lead from the timing light to the number one spark plug.
If the timing light is a powered type then
Attach the power leads of the timing light to the battery - red lead to the + terminal on the battery and the black lead to the - terminal on the battery.

Loosen the distributor so you can adjust the timing, start the engine and press the timing light trigger and aim the timing light on the timing marks on the crankshaft pulley. Adjust the distributor to the recommended timing mark for your engine.
Turn off the engine, remove the timing gun and tighten the lock on the distributor.
