If test results are not as indicated above, replace faulty parts. ©© © IG S IG Engine Tune-up @® ® I LAMP LAMP FLOOR TEMPERATURE SENSOR When floor temperature warning lamp lights Check floor temperature warning lamp for the following items. 1. Open or short circuit in wiring harness. 2. Condition of ignition system. Refer to "Catalyzer Warning Lamp Lights" in the "Emission Control" section. Repair or replace faulty part(s) if necessary. EC404 Fig. ET-64 Checking floor sensor relay ET-30
Engine Tune-up TROUBLE DIAGNOSES AND CORRECTIONS Condition CANNOT CRANK ENGINE OR SLOW CRANKING Probable cause Improper grade oil. Partially discharged battery. Malfunctioning battery. Loose fan belt. Trouble in charge system. Wiring connection trouble in starting circuit. Malfunctioning ignition switch. Malfunctioning starter motor. Corrective action Replace with proper grade oil. Charge battery. Replace. Adjust. Inspect. Correct. Repair or replace. Repair or replace. (Trouble-shooting procedure on starting circuit) Switch on the starting motor with head lights "ON". When head lights go off or dim considerably, When head lights stay bright, a. Check battery. b. Check connection and cable. c. Check starter motor. ENGINE WILL CRANK NORMALLY BUT WILL NOT START a. Check wiring connection between battery and starter motor. b Check ignition switch. c. Check starter motor. In this case, the following trouble causes may exist, but in many cases ignition system or fuel system is in trouble. Ignition system in trouble Fuel system in trouble Valve mechanism does not work properly Low compression (Trouble-shooting procedure) Check spark plug firstly by following procedure. Disconnect high tension cable from one spark plug and hold it about 10 mm (0.39 in) from the engine metal part and crank the engine. Good spark occurs. No spark occurs. a. Check spark plug. b. Check ignition timing. c. Check fuel system. d. Check revolution trigger signal. e. Check cylinder compression. Very high current. Check the current flow in primary circuit. Inspect primary circuit for short. Check distributor pick-up coil operation. Check transistor ignition system. ET-31 a
