To set the timing on a 1991 Geo Storm, run the engine until normal driving temperatures. Turn off the engine. With a jumping wire, connect terminals 1 and 3 on the ALDL connector. (look under the compartment on the passenger side, it's a small box). Connect a timing light to the #1 spark plug wire and loosen the distributor cap. Start the engine, letting the engine idle. Aim the timing light at the timing belt cover, the white notch on the crankshaft pulley should line up with the 10 degree mark BDTC on the timing cover. Turn the distributor to line up the marks (if you had previously marked the cap to where the rotor is pointing before removing) After the adjustment is made, make sure the distributor cap is has not turned and tighten up the bolt. Take the jumper wire off the ALDL connector and then turn the engine off.
