SOURCE: Miss fire coil number 8 and coil A

You need to check the fuel delivery and compression of the engine. A miss is not always electrical.To test the injector power you need a noid light to check the operation of the injectors electrical pulse at cranking speed. If you find the light pulses consistently the injector can also be clogged as well.You need a compression tester to test the compression.You need to test all the cylinders since compression is now a matter of averages.No cylinder should be less that 10% of the rest. These tools can usually be loaned to you from a major auto parts store. Good luck :-)

SOURCE: No fire from coil to #1 cylinder

Ok since you did all that if you want to swap around fuel injectors taking note where you put cylinder 1 injector. Lets say you swapped it with cylinder 4 . Now if you get a different code say P0304 which is for cylinder 4 misfire then you know it is your injector at fault. These are wear items and should be replaced every 100,000 miles.
Also i would suggest if you dont want to do that is get some good high octane gas when you are completely empty and fill to 1/4 tank now put in Lucas Oil fuel injector cleaner and run the car till empty. Now fill up tank with high octane gas in see if this helps. Clear code after your second tank of gas and see if the code comes back. if code does pop back up then i would do the swapping of injectors as i stated earlier. I hope this helps and good luck with the diagnosis.

Coil pak not firing 97 lesabre 3.8 relaced non firing pak, didnt help.


If three coils plugged into ignition module, and one isn't firing. One coil fires two plugs, when you remove that one coil, use a test light at ignition module primary terminals, where that coil plugs in, have a helper crank it, if the light doesn't flash, replace the ignition module. You may want to disable engine so it won't start. I can't think what else it might be? I've seen this problem before, at that time, it turned out to be the ignition module that was faulty.

I have. A 1996 60 HP evinrude stalled out,put new plugs in it,no fire from plugs....and also what is the proper position of the fuel (red tab)


No fire to plugs. Replace the coil? Been a long time since I worked on these. I believe that they are set up like lawn mowers. They have a magneto to fire the coil. They can get rusty and not let the coil fire. Just something to check.

Why are two spark plugs not firing?


This is likely a waste fire ignition system where one coil is firing two plugs. This is a less expensive system for the OEMs and is used in many models. I would swap the coil with another to assure that it is the coil and not the Spark Control Module.

If problem moves with the coil replace the coil.
