I have power to my coil packs but I am not getting any spark

So my kia stalled a while back and when i went to turn it back on it wouldnt. the engine was rebuilt a few months ago. so i went ahead and got new coil packs because it wasnt getting spark but the wires leading to the coil packs where getting power.that didnt work the wires still have power but im still not getting spark
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
If you scan the computer and monitor the crankshaft and camshaft sensors, you will see one of them not working properly to send a signal that the computer will use to make the coils send a spark. You will not see an RPM signal from the crankshaft most likely. Replace the sensor if the connector is okay and then you should get spark. A computer scan for codes should be done to make sure there is no other problems once this is done. If you’d like to get this fixed, consider YourMechanic, as a certified technician can come to you to perform these checks and diagnose your starting issue firsthand.

If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
With the ignition switch turned on, primary (battery) current flows from the battery through the ignition switch to the coil primary windings. Primary current is turned on and off by the action of the armature as it revolves past the pickup coil or sensor.
The supply to the ignition supply isn`t fused, so if you`ve shorted it to the crankcase, it`s likely damaged the wiring and ignition switch. Likely that the ignition switch has burnt out. If you run a wire from the battery +ve to the coil, the engine should start. Replacing the switch is likely to be the solution.
An ignition coil pack takes the low voltage from the battery and boosts it to the level where it can cause a spark to bridge the gap in a spark plug. This then ignites the fuel and air in an engine`s cylinder. Hence, ignition.
A Bad Crankshaft Position Sensor

The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.

If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
Once the ignition switch is prompted by key or the push of a button, it activates the voltage from the battery to the ignition coil to produce the engine spark. The engine spark from the coil or coils is directed to the spark plugs to ignite the fuel to make the vehicle run.
Blown Fuse

If there has been a surge, a fuse that controls the fuel pump, the fuel injectors, or another component that`s vital for your car`s functioning, it may be the cause of your car`s failure to start. Unlike most of the other problems, this is one that you can check yourself, if you want.

The primary winding of an ignition coil will typically contain 150 to 300 turns of wire; the secondary winding will typically contain 15,000 to 30,000 turns of wire, or around 100 times more than the primary winding.
The voltage reaching the coil may be 12 volts , or about 7 volts if the coil has a ballast resistor . Most electrical equipment works on 12 volts, but most modern cars have a resistor in the ignition system to assist starting. The coil in a ballast-resistor system is rated at 7-8 volts instead of 12 volts.
Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.
As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.
If your engine is not sparking, it may be due to a problem with the CDI box. However, other potential causes of no spark include issues with the ignition coil, spark plug, or wiring.
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
It is an electronically controlled pack of ignition coils regulated by the car`s computer and is used to create the spark for each engine cylinder`s spark plug.
A coil pack, simply put, is an electronically controlled pack of ignition coils regulated by the car`s computer.
An ignition coil produces a high voltage output on its secondary when the current flowing in the primary winding is interrupted. The first step in generating a high voltage from an ignition coil is to store energy in the inductance of the primary winding.
Linked to the car`s ECU, the ignition coil controls the sequence and current to the spark plugs, and is vital to the running of the engine.
Yes, if the points are open and/or the electronic module is NOT CLOSED then you will measure battery voltage on both the coil (+) and coil(-) terminals. Since there is no current flowing through the coil (no path to earth) then both sides of the coil will be at the same potential.
Vehicles with bad ignition coils often run roughly. This means, when your vehicle is idling, you may notice a rough feel or sound. Your vehicle may also experience a drop in power. As a result, a bad ignition coil can make it acceleration more sluggish.
The ignition relay is one of the most important electronic relays found on modern vehicles. It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle`s ignition system, and some of the fuel system`s components.
Hard Starts and Stalling

If an ignition coil is malfunctioning and not delivering the required voltage to the spark plugs, you will find it hard to start the engine. If your vehicle stalls when you stop and even shut off completely, it could be a bad ignition coil sending irregular sparks to the spark plugs.

If you suspect the coil is dead, you can also remove the coil, plug it back in, and use an ignition spark tester like OEM 25069 to determine if the coil is firing. You can also use a multimeter to test resistance.

I’m getting power to distributor coil, but I’m not getting power to the spark plugs.
ANSWER : Hi there. Check the spark plugs with a spark adapter tool to see if there is a park induced from the coil. If there is no spark, then the spark plug wires could be burned and need replaced. If the tool is getting spark, then the spark plugs need replaced. If you need further assistance with your ignition system, then seek out a professional, such as one from Your Mechanic, to help you.

Need to replace bad spark plug & coil pack on Ford Expedition but not sure what else I need besides the plug and coil pack?
ANSWER : Hi There,
I would recommend having an expert from YourMechanic come to your location to take a look at the vehicle to first determine what the cause of the misfire is if this has not already been done. Engine misfires can be caused by many different problems and are generally caused by either a spark or fuel issue or in some cases, a combination of both. Spark related problems generally will result from things like ignition coils, crankshaft position sensor, spark plugs, spark plug wires or ignition modules not working properly. When the misfire results from a fuel related issue, this is commonly related to a lean fuel condition (lack of sufficient fuel supply to the motor). Fuel related misfires can be caused by many different things such as low fuel pressure, faulty or dirty fuel injectors, a faulty O2 sensor, a dirty or failing mass air-flow sensor, a faulty or dirty idle air control valve or a vacuum or intake leak. When the fuel supplied to the combustion chamber is insufficient, this results in an ignition (spark) that is igniting a less than balanced load of fuel and air. This results in a misfire or an explosion in the cylinder that is much less powerful than the other cylinders. This creates a loss of power that resonates throughout the motor additionally causing other problems with ignition and fuel timing. Due to the number of different things that may cause an engine misfire, the quickest and easiest way to diagnose this type of problem is to hook the vehicle up to a scanning tool which will download any potential fault codes that may have registered in the vehicle’s computer as a result of the poor running condition. I would recommend having an expert from YourMechanic come to your location to diagnose your misfiring problem.

Engine light fault. There was a bad spark plug and a failed ignition coil. Replaced both the coil pack or spark plug.
ANSWER : Hi there. If the light is coming on then shutting off and returning on, then if the issue is for the same coil, there could be an issue with the wiring on the coil plug. Check the wiring on the coil plug and see if the wires are split, broken, or burned. If there is nothing wrong with the plug, then the main engine harness has an issue / short and may need replaced. If you need further assistance with your ignition system, then seek out a professional, such as one from Your Mechanic, to help you.

Cylinder one makes no power even though it gets fuel and spark.
ANSWER : Hello,
It sounds like you may have a faulty fuel injector at cylinder #1, a faulty crank sensor or potentially a vacuum leak. A bad crank sensor can easily cause misfiring and timing problems. I would suggest also checking connectivity at each of the fuel injectors, specifically at cylinder #1. You may also want to check the ignition control module to be sure it is relaying power to each of the coil packs. If you need further help with this, please reach out to us here at YourMechanic as we are always here to help.

Coil pack keeps cracking.
ANSWER : The ignition coils are only meant to withstand a high electrical charge whereas the spark plugs can withstand that as well as the explosions within the combustion chamber. It is possible that you could have a small crack in your intake manifold or cylinder head allowing combustion chamber temperatures to be exposed to the ignition coil, causing the burning. I would recommend having a professional run a compression test on the cylinder in which this is happening as it is likely the cylinder will not have as much compression with a crack in it.

Car t
ANSWER : If you recently changed the coil pack, then you should return it for a replacement. If you got it from the dealer then you should be okay, but if you got a used one or one from an internet source, you may be out of luck getting it replaced. Some aftermarket coil packs are known to not last very long. This is why they are so inexpensive versus the factory dealer version. If you’d like, you could get a technician to inspect the cause of your plugs loss of power issue. A certified mechanic from YourMechanic can come to your location to pinpoint the fault and perform a repair if needed.

Spark plug chaos. Rubber stoppers are preventing the spark plugs from coming out.
ANSWER : Hi there. Try using a pair of small needle nose pliers to pull off the rubber boots from the spark plugs. As you pull, twist the rubber boots to break them free. If you cannot get the rubber boots off, then try using some mineral oil on the boots to aid them off, then clean off the oil with soap and water with degreaser. If you need further assistance with removing the boots from the spark plugs, then seek out a professional, such as one from Your Mechanic, to help you.
