All Saturn Ions accept a distributorless ignition process. Most causes of ignition step problems can't be corrected by a non-expert, however there are a meagre matters you can arrange to disclose a dilemma's lodging. It primarily involves checking for sparks on the Glimmer plugs and ignition coils.
Instructions
Spark Tests
1. Remove a arena plug wire from the plug and connect it to a Glimmer tester. Ground the tester to the engine, Eccentric person the engine and scrutinize for a athletic Glimmer. Repeat for all the Ion's wires.
2. Research the wire's resistence with an ohmmeter whether there was a impotent Glimmer or no Glimmer. Modify a wire that measures else than 12,000 ohms.
3. Disconnect all four Glimmer plug wires from the ignition module towers. Bear someone else Eccentric person the engine for a infrequent seconds and attending for alternating sparks between the towers.
4. Switch the coil pack's positions provided no sparks come forth on one of them and Eccentric person the engine again. Moderate the coil pack whether the equivalent pack has no sparks; moderate the ignition module provided the twin domicile has none.
5. Proceed with the no-spark attempt provided no sparks arrive on all four Glimmer plug wires or both coil packs.
Check the resistance directly, see if the sensor is still magnetized and check the sensor wiring's continuity. Replace the sensor with any problems.11. Test the sensor's voltage if the resistance met specification.
Proceed to Steps 2 and 3 whether there is movement, and Steps 4 wound up 7 provided there isn't.
7. Disengage the six-pin connector from the DIS module. Turn the ignition switch to "On" and measure the voltage to ground at terminal A (with a voltmeter). Check for a blown fuse or shorted circuit if there is no voltage.
8. Unplug the five-pin connector from the module, and check the resistance of terminal E to ground. There's an open in the circuit resistance is above 200 ohms and a loose terminal or a faulty module if below 200 ohms.
9. Measure the resistance between the crankshaft position sensor's terminals A and B. (Disengage the DIS module's five-pin connector first). The resistance should be 700 to 900 ohms.
10. Remove the crankshaft sensor from the engine if the resistance was off.
No-Spark Test
6. Wristwatch the dashboard tachometer for signs of mobility while cranking the engine.Set the voltmeter to the AC volt scale, probe terminals A and B of the five-pin connector and crank the engine. Replace the sensor if it puts out less than 200 millivolts.
12. Check for voltage at terminal A on the DIS module six-pin connector. Check for a blown fuse or an open/short in the circuit wiring if there is no voltage. The DIS module is at fault if there is voltage and no loose terminals.
