How do I replace a coilpac on a 1998 for f150?

Hi there,

First of all, make sure the ignition switch if off. Then you remove the ignition coil electrical connectors from each coil pack. Then you number or label each spark wire so you can put them back in their original location. Then remove all spark plug wires from ignition coil pack. Then remove the ignition coil pack, four mountain screws and remove coil pack

Hope these help.

How do I replace a coilpac on a 1998 for f150?

They are usually bolted down with a 8mm bolt. Remove that bolt, unplug the connector and pull out the coil pack and boot. Some Fords you'll need to remove the fuel rail to get the coil packs out.

Coil pack only firing 2 cylenders

I'd add the information on how to test the coil packs yourself to make it a more complete thread...

How to verify if your coil packs work!
Engine worked with: 1996 maxima
Requires: An ohmmeter (cheap purchase at radio shack....)
Conditions: Make sure your engine is cold, or it'll be hot on your hands
you have 6 Ignition coil packs. 3 up front and 3 near your firewall. (when asking for new ones, they are referred to as L and R)

3 are hidden behind the plastic piece on your engine that says NISSAN... simply remove the bolts and remove the plastic piece.

once removed, you should see 3 coil packs. un plug and test them one at a time.

I won't go into how to remove them since it should be fairly obvious Simply remove both bolts (do one coil pack at a time...) and pull the coil pack out. i had one where it was very hard to get out... so you may have to pull hard...

Once out, look at the area where you removed the electrical plug. You should see a "+" on the back end of the electrical plug. There should also be the letter "B"....
the spot where you see the positive symbol, means that's prong number one on the electrical connector.

To test:
Turn on your ohmmeter and place the positive wire on the 1st prong in the electrical plug of the coil pack. The negative wire should be touching the middle prong. Verification of the ohmmeter at this time should say "0" aka infinite... if it's anything else, the pack should be changed. Next test: reverse the wires... positive on the middle prong and negative on the 1st prong.... on a new coil pack, it should give a value of approximately 1.3-1.7 mega ohms. If any of the readings are off, replace the coil pack.

Note: Firewall coil packs are extremely easy to find, simply look in the cracks of the intake header. you'll see 3 similar looking coil packs to the front ones. The exception with these is that they are longer and look a slight bit different. removal is the same process as the front coil packs. Simply pay special attention to not dropping the screws in the intake area... it'll be hard to get out.

to test: follow the front coil pack testing method. Look for the Positive symbol, this is your first prong... and go from there.

Good luck (remember rated this help).

Dont know how to take master cylinder off to replace coil pack

You shouldn't have to remove are the steps from the tech manual:

Removal & Installation
  1. Disconnect the negative battery cable.
  2. Label and disconnect the spark plug wires from each of the coil pack towers.
Ignition coil removal—2.4L engine

Ignition coil removal—3.3L and 3.8L engines

  1. Disengage the electrical connector from the ignition coil pack.
  2. Remove the coil pack mounting fasteners.
  3. Remove the coil pack from the vehicle. If equipped, remove the coil pack from the mounting bracket.
To install:
  1. Place the coil pack into position on top of the engine valve cover, or mounting bracket, if equipped.
  2. Install and tighten the coil pack mounting fasteners to 9 ft. lbs. (12 Nm).
  3. Plug in the electrical connector to the ignition coil pack.
  4. Connect each spark plug wire to each corresponding coil pack tower. The coil pack towers are numbered with the correct cylinder identification. Be sure that the spark plug wires snap firmly onto each coil tower.
  5. Connect the negative battery cable.

Arcing at coil pack. misfire on #1 cylinder. car ran rough, now won't start. How do i change the coil pack?

follow the spark plug wires to the coil packs...i believe now, you have to physically crawl under the vehicle and look at the back of the engine, to the coil packs....remove all three packs as an assembly and then remove the individual pack that you need to replace...or if you feel good enough, see if you can run your hands the back side of the engine, and remove the coil packs that way....good luck...if you need help....just call in edmonton?
