To amplify the voltage going to the spark plug
Most automobiles will not start with a nonfunctioning coil pack. The coil pack will cause the spark plugs not to fire.
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.
To check a coil you just need to take out your spark plug but leave it plugged into the coil and ground the spark plug while trying to turn it over. If it is a good strong spark than your coil is fine. If it doesn't spark than unplug the wire going to it and try it again if it doesn't spark than it is a good chance your coil is bad. if it does spark than it is a wire problem. Also make sure that your spark plug is gaped correctly, usually at about 0.030.
No. The coil provides the spark and the module tells the coil when to spark.
If you do not have a key the coil is not going to spark.
The purpose of a coil pack is to supply the spark to the spark plugs.
You apply 12 volts to the coil primary and then release it . The electricity will go through the secondary coil and spark the spark pug.
coil kaput buy new
Even though you replaced the coil, it may be bad. You should test that first. If the coil is okay, it could be that the ignition wires need to be replaced.
every gas engine has atleast one coil, in a vehicle older than say 10 years it probably has one coil that leads to a distributor which has a spark wire going to each piston. The SVX has SIX coil packs, one on each cylinder. No spark plug wires, no distributor.
you might want to check your coil wire. Also depending on the vehicle, the crank sensor may have failed.
the coil is bad
Defective new cap/rotor?
coil makes enough juice ( Amp) to spark the spark plugs. A faulty spark plug stops the coil to empty all the juices it has made and this makes the coil itself goes bad.
Either your coil is shot or your kill switch is stuck closed. If you warm it up (above freezing) and it still doesn't have spark, bet on the coil being bad or if you are lucky, the sparkplug wire is cracked and grounded. you can isolate & test the coil by removing the engine shroud, you will find one thin green or black wire going into the back of your coil, disconnecting this wire will isolate the coil from the rest of electrical system. recheck spark with the wire disconnected, if you still dont have spark you need a new coil, if now have spark it means your coil is working and either a switch or a bad wire is grounding the system.
stick it on the spark plug, its a coil on plug stick it on the spark plug, its a coil on plug
The spark is looking for the easiest path to ground, you might have an issue with either your plug wires or plugs that is causing too much resistance. Also your coil pack might be going bad.
Check the coil or coil packs if equipped.
The spark is always blue. If your coil is bad your engine will misfire.
After testing the coil for proper resistance and finding they had the proper values, I swapped them from one side to the other. The coil with no spark still had no spark. A new coil was installed, problem solved.
DEPENDS ON THE YEAR AND MOTOR,DO YOU HAVE SPARK PLUG WIRES?IF NOT,THEN YOU HAVE A SEPERATE COIL FOR EACH SPARK PLUG THAT SITS ON THE TOPS OF THE PLUGS,IF YOU DO HAVE SPARK PLUG WIRES THEN JUST FOLLOW IT FROM THE SPARK PLUG TO THE COIL!HOPE THAT HELPS
you need a new distributor That can be one cause for this, could also be bad ignition coil, coil wire, or even spark plug wires. Test for spark at the coil, then coil wire, then the plug wire.
Perhaps bad coil or coil pak?
The spark travels from the coil to the distributor then from the distributor to the plugs. So if you have spark going into the distributor but not coming out to the plugs, I would blame the distributor cap and rotor being at fault.
