Are coil plugs on a 2003 Ford focus the same as the spark plugs or no? Also are the ignition wires the same as sparkplug wires?

check the timming, check spark plugs, check compression of the cylinders, check spark plug wires and if all else fails replace the ignition coil module

Your coil pack is where the spark comes from,if you aint got spark comeing from there to plugs the pack is bad

follow the sparkplug wires..One end goes to the plugs..The other end goes to the coil...If you dont have sparkplug wires then you have coil-over coils..Thats where the coil sits right over the spark plug...

I am writing you the method on how to change sparkplugs, you may now have an idea where spark plug is loacted.

The Ford Expedition uses eight spark plugs to accommodateits eight-cylinder engine. Replacing the spark plugs every 75,000 miles is animportant part of overall vehicle maintenance. 1. Disconnectthe negative (black) battery cable from the battery terminal. Remove thewiring harnesses from the spark plug coils. There will be four on each side ofthe engine block, which you can remove by simply pulling them out of the sparkplug coils. 2. Unscrew the 7mm bolt from each of the spark plug coils usinga socket wrench and 7mm socket. 3. Pull each spark plug coil out of the engine block. Pull themout slowly, being careful not to damage or tear the coils. 4. Use a socket wrench and spark plug socket to unscrew eachspark plug from the engine block. Once you remove these, discard them. 5. Place the new spark plugs into the engine block and tightenthem using the socket wrench and spark plug socket. 6. Slide the spark plug coils back into the engine block. 7. Bolt the spark plug coils back into place using a socketwrench and 7mm socket. 8. Reattachthe wiring harnesses to the spark plug coils. 9 . Connect the negative battery cable to the negative batteryterminal.

Welcome to Fixya.

Here's the procedure how to replace the ignition coil pack of your car.


•1
Understand basic safety procedures. Any time you work on your Ford Focus, you should set the emergency brake and disconnect the negative, or ground, cable from the battery. Some mechanics recommend you isolate the cable to prevent accidental contact, which could spark a connection.
•2
Release the spark plug wires from the Ford Focus ignition coil pack. You may need to pinch or press a release to unlock the wires.
•3
Use a socket set or a small wrench to unbolt the ignition coil connectors. You also need to undo the capacitor electrical connectors. As you work, make note of which connectors go where--this pays off you when you reassemble the parts.
•4
Locate the bracket that holds the ignition coil pack and the electrical capacitor in place. Undo the fasteners that secure them.
•5
Separate the Ford Focus ignition coil pack from the mounting system. Replace the old Focus ignition coil pack with a new one. Verify the new ignition coil pack works with your engine, even if you use a universal ignition coil pack.
•6
Reassemble the parts. If you have a Torque wrench, use it to tighten the ignition coil bolts with 7 inch pounds of torque (10 Nm).

I am having the same problem. I don't want to go to the dealer because they will charge me way too much just to look at it. I also have a 2003 ford focus se 2.3 pzev. Clicking sounds happen in first gear only.

there is no wires on a 2005 focus ..theres coil packs
the plugs are right on top of the motor .remove the retaining screw with a 5/16 nut driver and pull up on the rubber boot . use a extention and a 5/8 spark plug socket to remove the sparkplug ..repeat for the other three....

we are trying to figure out how to change sparkplugs in a 2003 cadillac deville

WARNING: Risk of Electric Shock

Check your spark plugs and wires yourself. Remove one sparkplug at a time from the engine block, plug the wire back on, place the sparkplug on the engine or vehicle body so that the outer thread of the sparkplug would touch the body, or engine (GND) you can secure it with a cellotape or so. Turn the ignition key to the START position and when starter is spinning wach for high voltage sparks appearing between the body,engine or gasket and the tiny black end of the sparkplug called electrode. If there's a sparks, than it's fine, othervise try to get one working sparkplug and to retest this. If now it works then your sparkplugs needs to be replaced. Othervise check the resistance of the high voltage coil primary windings. this should be something between 0.2 and 10 ohms, when coil is disconnected from vehicles wiring. I just do nts remember the exact figure. If multimeter doesn't show anything, replace the coil, otherwise check if the supply current is flowing to the coil plug when IGN is ON. If it's fine then check the COM line at the same plug, using analog muldimeter is the easiest and not harmfull way to do this. If COM isn't comming You might need to go deeper into ECU, or even to replace it. If COM is fine then it would identfy that coil itself is faulty.

Update me about your progress

Good luck
