find the timing spec on the label under the hood ( i think its 10 degrees BTC) get engine to operating temperature find the grey plug in the engine compartment labeled "diagnosis" open the cover and with a jumper wire, connect tmls. TE1 and E1 (this makes the engine run at base timing) clamp timing light around #1 plugwire clip power and ground leads of timing light to battery shine on timing marks, if the timing is off loosen the 2 12mm bolts securing the distributor to the head and twist until the mark on the pulley matches the spec. tighten the bolts remove timing light and jumper

IGNITION TIMING: Carburated models Without vacuum advance hose connected: 3 degrees BTDC. With vacuum advance hose connected: 12 to 18 degrees BTDC.

1990 through 1993 fuel-injected models With test terminals T and E1 grounded: 10 degrees BTDC. Without test terminals T and E1 grounded: timing fluctuates between 7 and 17 degrees BTDC.

1994 fuel injected models With test terminals TE1 and E1 grounded: 10 degrees BTDC. Without test terminals TE1 and E1 grounded: timing fluctuates between 7 and 17 degrees BTDC.

To set the timing belt on a 1993 Tercel the cam shaft markets must be lined up top dead center. There are arrows engraved on the engine labeling where exactly to install the belt. Failure to correctly set the timing belt can lead to catastrophic engine failure.
