So Fix it

Failed ignition timing means the timing setting for a car engine was inspected and is outside the guidelines for pollution control. The timing must be adjusted to pass a future inspection.

Significance

Smog technicians check vehicle timing and evaluate the settings. Timing adjustments, if necessary, are easy for mechanics to do and should not require more than a few minutes of labor in most cases. Timing specifications are located under the hood, on the timing belt cover or in owners manuals.

Considerations

Consumers should caully select a mechanic to adjust timing settings, as dishonest opportunists have a reputation of exploiting failed ignition timing for financial gain. Second opinions are recommended, particularly if more than a simple adjustment is required.

Effects

Engine timing ers to the rate at which spark plugs fire. The plugs burn a certain amount of fuel, and the fuel is broken down and emitted through the exhaust system. Larger amounts of carbon monoxide are created when the timing is inefficient, a circumstance that is detrimental to the environment.

A Honda Civic will alert you every 10,000 miles that it is time to perform standard maintenance. When this happens, a light will come on in the instrument panel. If you take the car to a Honda dealer for service, the mechanic will reset the light for you. However, if you perform system maintenance on your Honda Civic by yourself you must reset the maintenance indicator manually, using your ignition key.

Instructions

1

Put the key into the ignition and turn it to the "On" position but dont start the vehicle. Find the trip meter button located near the bottom of the dashboards instrument panel.

2

Press the trip meter button and hold it down for 10 or more seconds.

3

Continue to press the trip meter button and turn the ignition key to start the car. Wait for the light to turn off.

Nissan is a popular car brand in the United States. Nissans are manufactured in both four- and six-cylinder models. Replacing the ignition coils on a four-cylinder is the same as a six-cylinder, just with fewer steps. Although diving into your cars engine may sound a bit daunting, replacing the ignition coils on your Nissan engine is not quite as complicated as it may seem.

Instructions

1

Lift the hood of your Nissan and prop it open. Identify the cylinders on the rear side of the engine. These are cylinders 1, 3 and 5. This is where you will find the coil harnesses.

2

Notice the green tabs on the grey coil harnesses.

3

Push down on the inside of the harness to release it from the coil. This may take a good bit of pressure.

4

Place the harnesses, in the order removed, on the ground so that you can keep track of which cylinder each belongs to.

5

Remove the 10 mm bolt that locks each of the three coils to the engine.

6

Remove the coils from the engine.

7

Remove the cover plate on the front of the engine by detaching the four screws that hold it in place. This will expose the coils on cylinders 2, 4 and 6.

8

Remove the coil harnesses in the same manner as the rear harnesses were removed.

9

Set the harnesses aside in order.

10

Remove the three 10 mm bolts that hold the front coils in place.

11

Slide the front engine coils out from the engine block.

12

Place the new coils inside cylinders 2, 4 and 6.

13

Tighten the coils with the three 10 mm bolts.

14

Position the harnesses over the coils.

15

Reattach the cover plate and tighten the four screws to secure it.

16

Place the new coils at the rear of the engine.

17

Attach the coils with the three 10 mm bolts and tighten.

18

Place the coil harnesses into position and attach them to the coils.

A Mazda key will not turn in the ignition for three main reasons: a problem with the physical key code, a tight steering column or a faulty ignition switch. In each case, the key is not connecting properly with the ignition switch.

Mazda Key Code

The Mazda key can contain a computer chip in its head specifically coded to communicate with a particular vehicle. Starting the ignition requires the correct code. A key inserted without the correct code may not turn at all or may only crank forward without starting.

Steering Wheel Lock

A steering wheel has a lock mechanism to prevent the key from turning in the ignition, a security device to prevent theft. To start the ignition, pull and hold the steering wheel to the right or left before you turn the key.

Tires Turned Tight

A key may not turn the ignition switch when you park the car on a hill with tires turned to the curb or out too tight. This position places pressure on the locking pin in the steering column and prevents it from moving. Rock the steering wheel left and right to loosen the locking pin and start the car.

Lose Ignition Switch

The ignition switch and starter can become loose and slip so the key fails to make correct contact. You can try to push the key in as you turn it. The starter may require replacement or at least tightening.
