I have a 1995 Ford
using FixYa. If you do not
have sufficient voltage and cranking power, the car simply won't start. Have
someone attach booster cables to your battery if the engine seems to be turning
over slower than normal. If the battery seems charged, and the starter motor
still doesn't turn the engine, the problem may be in your starter motor itself,
or the battery cables. Changing the starter is not too complicated, but if you
decide to attempt this, try to find someone who has done it before to help you,
or buy a do it yourself manual that has a description and pictures of what you
need to do. You can also test to see if the voltage is going thru to the
starter motor, if not some times you can cross jump the solenoid and start the
car. Remove a spark plug wire from your spark plug and use an insulation
handled screwdriver to ground the metal fitting inside the spark plug boot to
the engine, and have someone turn the engine over while you watch for a spark.
You should have the metal screwdriver shaft about an eighth of an inch from a
clean metal surface on the engine, and be careful not to touch any un-insulated
parts of the tool while testing the plug. If you do not have a spark, you have
an ignition circuit problem, and depending on the vintage of your vehicle, you
may have to replace anything from a coil wire to an ignition CPU, or computer. In
addition to above, some related points to check are as under:-
1. The no ignition light is likely
caused by either a problem in the electrical system or in the fuel system. Your
engine stops running because it is not igniting gas in the cylinders, this
occurs either because there isn't gas to ignite, or because it lacks the
electrical charge to ignite it.
2. Drive the car up and down steep
hills. Does this change the performance of the engine, or cause it to no
ignition light? This might indicate a clogged fuel filter. Replacing the fuel
filter is relatively cheap and easy once you find out where it's located.
3. Does the car idle roughly and no
ignition light when at idle? If your car has a distributor, you may need to
adjust the timing. With the right tools and know how, this is an easy and free
task. If your vehicle has fuel injection, you can check the injector by using a
screw driver or mechanics scope. The injectors will make a clicking/snapping
sound if working. No sound would indicate a bad injector available at most DIY
auto parts stores. Also check the ICM, idle control motor that controls the air
4. If your car has a distributor, you
might consider changing the cap, rotor, wires and plugs. This is effectively a
tune up. This can usually be done even by a relative novice to car repair, and
take a couple of hours with the right tools. It seems counterintuitive, but
even the wires and distributor decay over time, and transmit less electricity.
This tune up may solve your no ignition lighting problem -- even if not, your
car should run better and get better mileage.
5. If your car diesels when you turn
off the ignition, it often signals the need to replace the spark plugs.
Dieseling describes the situation where you turn off the key, yet the car
continues to run for a few seconds or longer, eventually sputtering to a stop.
6. In rare cases, your car may no
ignition light due to what is commonly called a "vapor lock". It is
actually a vacuum in the fuel line that causes fuel to eventually stop reaching
the engine. Try opening your gas cap. If you hear a "whooshing"
sound, like when you open a can of coffee, it's vapor lock. Now try starting
the car. It should work after a couple tries. This is usually found only in
older cars. If you have it, this will probably happen again, so your fuel line
should be checked for blockage. A cheap fix is to drill a small hole in your
gas cap to allow air in and prevent the vacuum from forming, but it should not
be left this way.
accept the solution if the issue is resolved or else revert for further
