Why is there power to the coil but the coil does not spark?
EricShann
81 Dodge van 250 . I have same prob and have replaced ign module, coil, and distributor pic/up but still have no spark. I traced wire to module from coil and found that I only have prob when ign is on with this wire. looks like I have a dead short on this wire between ign and module as the module controls pulsating spark to coil then to distributor pic/up then to spark plugs. Seems like no spark no go.

1984 Chevrolet caprice 3.8 v6 no spark to spark plugs?
check for power at coil if you have power with key on then check for spark comming out of coil and coil wire if you have spark there then make sure distributer rotor is turning by removing cap and cranking over
1990 Mitsubishi Valant Power transferrs to the coil but coil is not transferring power If the coil is getting power why is there no spark?
The coil is bad or the ignitions system is grounding out somewhere.
1984 Nissan 300zx have power to coil but no spark?
your coil is bad replace with new on
What is a coil and how does a bad one effect a vehicle?
A coil is what gives you spark it distributes the power to your spark plugs so it would run bad or not at all check for spark. The coil produces the power for the spark to ignite the fuel/ air mixture in the combustion chamber of the engine . The distributor systematically distributes or places that spark to the spark plugs in the firing order .
97 Geo Metro cranks but gets no spark?
A 97 Geo Metro that cranks but gets no spark is not getting enough power to the ignition coil or the coil itself is bad. The coil use the 12 volts of power provided by the battery and alternator to generate a very powerful spark.
What is wrong if there is power into the coil but none coming out?
More than likely the coil is bad. A spark occurs when the power to the coil turns OFF. Ignition points or the ICM breaks the voltage when it's time to fire a spark. Just having voltage to the coil isn't enough.
What are symptoms of faulty ignition coil?
Symptoms of a faulty ignition coil are power to the coil checked with a multi-meter and no power out checked by pulling any of the spark plugs, placing it back int the spark plug cap, grounding out the end of the spark plug against metal while you have someone turn the motor over lack of spark would indicate no power from coil. You can also check the output side of the coil with a multimeter but note that your reading will jump instead of staying constant.
Why is your distributor not firing on your amc 304?
Check your coil with an inline spark tester. If no spark to the distributor check for power to the coil. If power to the coil but no spark then coil is bad. If coil is sparking the problem is in the distributor. If no power to the coil trace back the wiring to the power source (battery voltage) Check the points to make sure they're gaped properly & not burned or corroded. Check cap & rotor while you're in there also. while the cap is off turn it over and check to see if the rotor (shaft) is turning.
Why is there no spark on a 1993 Subaru Impreza?
Check that battery has power. Check that coil pack has power and is grounded. Ground out one spark plug and see if there is any spark. If there is no spark, then it is either a fuse or your coil pack is bad. Rule out that the coil pack is good and that your spark plug wires are bad. Test them all individually. Don't get shocked by the 20K volts from the ignition, it really hurts.
Whats the purpose of a coil in a car?
the coil increases the electrical power from the battery before it is sent to the spark plug.
How does a motor generate spark to the spark plugs?
Answer One of three ways ,magneto , coil, high energy ignition.magneto use's magnets to energize the coil, coil use's the battery's power run through the coil then the points open and the spark is released. H.E.I. use's battery power in much the same way as the coil but the coil is internal and the points are electronic. CheckSpark can safely and quickly check all three type,s.
Why don't i have spark on jeep Cherokee laredoi replaced engine i had spark before replacementthere is little bit of power going to coil but none coming out of coil.?
get a new coil. a coil on an engine is designed to take a little power and make it into BIG power. also check wires and connections going to coil. your problem sounds like the coil though. good going in, nothing coming out. there's your problem.
