Question about 1985 Nissan Pickup

1 Answer

My 85 nissan pick-up has 2 coils, one has no spark

My 85 nissan pick-up has 2 coils and 8 plugs, it is a 4 cylinder. Can some one explain how this system works? One of the coils has no spark, I installed a new one, and this did nothing. The truck has been running fine till this problem. Now it runs like it has a dead plug or 2.
I am a ford man and have no idea what makes this thing tick.
Any help out there?

Answer: Your truck’s ignition system should "fire" both coils during normal operating conditions. On full acceleration, it "cuts" one coil out. All this is controlled by the PCM (computer). You could possibly have faulty wiring also.

What is the firing order for a 2005 nissan titan crew cab? Which one is cylinder one and where can I find it? PLEASE HELP!!!


The firing order is 1-8-7-3-6-5-4-2 and the #1 cylinder is located at the left front of the engine and the spark plug and ignition coil for the #1 cylinder will be the first ignition coil and spark plug on the front of the left side of the engine on top of the valve cover, and to remove an ignition coil dis-connect the wire connector to the ignition coil, then remove the bolt securing the ignition coil (usually this is one 10 mm bolt) and give the ignition coil a twist as you pull it straight up and out of the spark plug well, and if you are removing the spark plug then use a socket with an extension and swivel to loosen up and tighten the spark plug, but use about a 6 inch length of 3/8 inch fuel line pushed onto the spark plug to actually remove the old spark plug and also to start the new spark plug down inside of the spark plug well to reduce the possibility of cross-threading or damaging the threads for the spark plug. Here are some images to assist you and the ignition coil location image shows the right side of the engine for reference, with cylinders 2-4-6-8 and this was just the best image that I could find to make that diagram, however they are laid out the same on the left side of the engine 1-3-5-7, and let me know if you require any further assistance.

Replace spark plugs on a 2008 4 cylinder tribute


This is a fairly easy job. Do each cylinder one by one (removal and install), make sure to reinstall the coil on the same exact cylinder (DO NOT MIX UP). 1. Remove coil retaining scre 2. Pull upward on the coil to remove. 3. Remove spark plug (using a spark plug socket). 4. Properly gap new spark plug (if applicable). 5. Apply sprark plug anti-seize compound on plug threads. 6. Install plug. 7. Aplly coil boot grease on the coils' rubber boot tips. 8. Reinstall coil.

#8 coil pac, cylinder misfire...Need diagram The mechanic says I need a coil pack and spark plug replacement for the #8 ...Need diagram to figure out which one it is. it is


The #8 coil and spark plug are located on the drivers side rear of the engine. You will need a 7mm socket to remove the bolt that holds the coil down. After the bolt is out, pull the coil upwards and remove. Next you will need a 9/16" spark plug socket to remove the spark plug which is located in the hole that the coil came out of. The spark plugs in a 5.4L engine are sometimes frozen into the engine. If it is very hard to turn the plug, try spraying some WD-40 down the hole onto the plug and let it soak in for a while. Do not try to force the plug to turn, it will break and a special plug extractor will be needed to remove it.
Hope this helps you!

For the firing order and wiring routing2_bing.gif for the 8 plug 4 cylinder engine: (Plugs on the intake manifold side are coded "I", and on the exhaust manifold side are coded "E")

Wire to 1I should be connected to tower on the distributor facing directly to the front of the vehicle. Going counterclockwise from there, the order is (1I), 2E, 3I, 1E, 4I, 3E, 2I, and 4E.
