How to check coil pak on a 1993 lincoin mark 8

check the injectors might be dirty or sparkplug wires doesnt gve sufficient current to the sparkplug

The spark plugs from passenger side to driver side are 1-2-3-4 The coils from passenger side to drivers side are 4-1-2-3

the heater core is located behind your dashboard on the fire wall. you will have to remove the dashboard and components blocking you from getting to the heater core it is a very aggravating job but can be done with patience and will save you alot of money to do it your self

Hello, This code means your #4 cylinder is misfiring. There were 2 different coil systems used for the 2 engine styles that year. The top of the Intake manifold will need to be removed to provide access.

The 4 Valve engine used coil-paks and you need to mark the position of each sparkplug in relation to the post on the coil-pak. Check the terminals for corrosion, it may be fixed with a simple cleaning, or you may need a new coil-pak for this pair of cylinders. With most of the work already done, you may want to replace #4 sparkplug and the rest while the intake manifold is off.

The 2 Valve engine had a coil on each plug. Usually there is a 10,000OHM resistance from the top of the coil to the bottom terminal. You can take the coil into Autozone, Oreillys, or Advance and they may be able to test it. Again, now would be a good time to replace all the plugs while the intake manifold is off.

did u try the fuel pump

Check the classic symtoms here, first make sure the engine is getting fuel and spark. Make sure your distributor module is not bad, it is located inside your distributor. Next make sure your coil pak is not faulty. Also look at your ignition relays to make sure they are not blown. Also check ignition fuses. If all these tests prove ok and you have a distributor instead of a coil pak then check the wires to the module inside the distributor for slight wear marks on them that sometimes happens when the wires rub on the metal turning shaft in the distributor cap.

Yes start with the coil pak. There are three located on the front of the engine on the pass side, you probably know this. They are marked as to which cylinder each wire goes to, disconnect the wire for #5 cylinder, and if the engine misfire does NOT change, it is more than likely that Coil Pak. Replace it, and use dilectric grease on the two contacts when reinstalling it. Now, I have stumbled on this issue many times and if that does not cure the issue (I think it will), the coil module below the coil pack is probably bad...To remove this module, remove the coil paks, the electrical connector in front (has bolt holding it in) and I remember one bolt holding the module to the aluminum bracket.

Again, to be sure you can switch coil paks around to make sure it is a coil pak. When you switch the bad with a good, the misfire will follow the coil pak, if it does not it is the module.]

Hope this helps.

Let me know if this helped.

The cylinder closest to the passenger side is number one. Firing order is 1, 4, 3, 2 Where is your coil pack located in reference to the engine? I need this info to give you accurate placement of the spark plugs. Charlie
