That's not a hose, It's the main spark plug wire that goes to the center position on the distributor. That is how the spark gets to the distrubutor to be sent to the plugs.
I would suspect the coil itself, even with the wire connecting to the distributor cap removed, you should still see a spark from the connector on the coil to the body of the coil itself
Only if a faulty coil is causing a misfire. A faulty coil can be diagnosed easily by connecting an oscilloscope and looking at the waveforms.
This vehicle uses Coil ON Plug ignition coils. So you have to remove the coil and the rubber boot to get to the spark plug
Ignition coil is bad, is it right on top of the cap maybe a bad wire in the wirng harness or bad connector.
In a nonelectronic small engine ignition system, which of the following ignition components is energized by the power source first?
On the firewall. Upper right, above the exhaust manifold and steering column... Good hunting. PS. you will see a wire very similar to a spark plug wire connecting the ignition coil to the distributor cap... hope this helps..
The ignition coil is inside the ignition distributor.
No. The coil provides the spark and the module tells the coil when to spark.
Hi, I just replaced the spark plugs on my 2004 Ford Expedition with the 5.4 L engine. I'm quite a beginner and this is the first time I've done it, but the engine runs fine so I think I did it OK. I had a hard time finding the spark plugs because they are hidden in the engine block under a rubber boot, under the ignition coils. Each spark plug has its own little "coil on plug" ignition coil. But the ignition coils were easy to remove. You squeeze the electrical connector and disconnect the wires going to the individual ignition coil. Then you remove the one bolt that holds the ignition coil in place. Then you gently pull the coil up (you may have to pull it at an angle because the fuel rail is in the way) to disconnect it from the spark plug, and it will come out with the rubber boot attached. The rubber boot keeps debris from falliing into the well where the spark plug is located.
The thickness of a business card!
they a use a coil over plug type ingnition, each plug has its own small coil that sits right on top
you can ohm it out from primary to secondary. I usually do a good close up inspection of it . Look for cracks in rubber or sooty looking marks usually on back side for shorting to ground. If you suspect a bad ignition coil, or coil pack , replace it at Autozone.
