Start Engine - Check Base Idle Speed and Ignition Timing

1. Try to start the engine. Fully depress the accelerator during cranking.

Figure 1:

2. If the engine does not start, temporarily remove the fuel pump fuse (see Figure 1) or turn the pump fuse off with CONSULT work support. With the accelerator pedal fully depressed, crank the engine for 5 - 10 seconds to clear excess fuel from the combustion chambers.

3. Once the engine has started, warm it up until the engine coolant temperature indicator points to the middle of the gauge. After the normal operating temperature is reached, ensure the engine speed remains below 1,000 rpm.

4. At normal operating temperature, run the engine at about 2,000 rpm for approximately 2 minutes under no-load. Race the engine (2,000 - 3,000 rpm) 2 or 3 times under no-load, then run the engine at idle speed for 1 minute.

Figure 2:

5. Turn off the engine and disconnect the throttle position sensor harness connector (see Figure 2). Re-start the engine and rev (2,000 - 3,000 rpm) 2 or 3 times under no-load, then run the engine at idle speed.

Figure 3:

6. Check the engine timing with a timing light (see Figure 3). (Specification is: 15° +/- 2° BTDC in "N" position)

a. If the timing is correct, proceed to step 7.

b. If necessary, adjust the ignition timing to the specified value by rotating the distributor after loosening the securing bolts. Then turn off engine and connect the throttle position sensor harness connector to the throttle position sensor and repeat steps 3 - 6.

7. At normal operating temperature, rev the engine (2,000 - 3,000 rpm) 2 or 3 times under no-load, then run the engine at idle speed.

8. Check the base idle speed (Specification is: 700 +/- 50 rpm in "N" position).

a. If the base idle speed is correct, proceed to step 9.

Figure 4:

b. If necessary, adjust the base idle speed by turning idle speed adjusting screw (see Figure 4). and repeat steps 7 - 8.

9. Turn the engine off and reconnect the throttle position sensor harness connector.

10. Start engine and rev (2,000 - 3,000 rpm) 2 or 3 times under no-load, then run the engine at idle speed.

11. Use CONSULT to clear any TPS DTC and verify that no new DTC has been set during the above procedure.

NOTE:
If either the ignition timing or the base idle speed required adjustment, correcting this condition should resolve the "crank, but no start" incident.
