Ensure transmission is in Neutral or Park and parking brake is set. Inspect crankshaft pulley timing mark and timing mark indicator on timing belt cover. Clean marks as required. Start engine, and warm it to normal operating temperature. Turn all accessories off. Attach timing light to No. 1 spark plug wire. Ensure idle speed is correct. See IDLE SPEED SPECIFICATIONS table in SPECIFICATIONS article.
CAUTION: Driving with jumper wire installed in monitor connector will damage catalytic converter.
Connect ground terminal "D" and test switch terminal "E" of monitor connector. Aim timing light at crankshaft pulley and timing cover timing marks. If ignition timing is not within specification, loosen distributor hold-down bolt and rotate distributor to obtain correct ignition timing. See IGNITION TIMING table in SPECIFICATIONS article. Tighten distributor hold-down bolt, and recheck ignition timing.

NOTE: With jumper wire installed, timing should be fixed. If timing varies, terminal "D" is not properly grounded.
