Ignition system maintenance and service
Ignition system maintenance and service Though newer spark plugs can often last
up to 100,000 miles, they can still get dirty or fail prematurely. Ignition
wires lose insulating ability, and the connection to the plug or ignition coil
can degrade as well These are some of the phenomena you'll encounter in your
ignition system as time goes on. In this short article, I just want to list some
common problems of ignition system in your daily use and the corresponding
advice for hopefully that they can be useful. A spark plug problem can be caused
by the presence of water inside, if it is the case, a dry piece of cotton cloth
will leave you at ease. However, if the situation does not improve at all, it is
time for a detailed checkup. If you have your ignition switch or steering column
heat up, try an ignition switch replacement when you find a corroded one in your
system, if not, loose connection or broken ignition switch wire. As a failed
start, there are several reasons for you to consult. First, the compression can
be too low inside the cylinder, a slipped or broken timing belt is the most
common cause. Second, not enough fuel in the cylinder, in this case, a fuel pump
that does not turn on, or is worn out or improper sensor data can be the cause.
The third reason is opposite to the second one, too much fuel, you'll need a
fuel system pressure test and examining scan tool data to help you identify the
cause. Fourth, the primary coil does not turn on or off. Check the primary coil
positive terminal with a voltmeter or test light for a simple blown fuse or open
circuit. Fifth, a short in the secondary ignition circuit, it could be the
result of a failed secondary ignition system insulation. Sixth, there is an open
in the secondary ignition circuit. This will quickly lead to the ignition
coil's self-destruction. To service your ignition, you can follow some fairly
easy procedures. By getting started, remove the fan shroud underneath the hood
of your car. First of all, remember to disconnect the ignition coil's primary
wires for your safety. Then you can get a compression test, the readings the
compression gauge shows should be within a 10 to 15 percent variation of optimal
reading from your service manual. Next, inspect your spark plugs to see if they
need to be changed. If it does need, install the new ones autel

exactly the same as the ones replaced, not in the length, but also the wire
route. Check your distributor cap, rotor as well as the ignition coil, if you
want to change the distributor cap, change it together with rotor. For ignition
coil, make sure the insulation is intact and that the connector is solid. Remove
the battery and connect a voltmeter to check the voltage. Be careful when you
remove it, you'd better follow professional instructions as to this move Autel

are all tight.
