Re: 1986 Nissan Maxima
It can be a few things, first check your timing belt. If your timing belt is fine, check to see if your car has a voltage regulator of some sort and make sure it is functioning. If that is ok than you'll want to think about changing the ECM. Good luck!

Re: 1986 Nissan Maxima
Reason for no spark would be ...
Bad crankshaft position sensor or distributor pickup (Sends pulse signal to ignition module and/or PCM that is necessary to trigger the ignition coil(s)). Bad ignition module (controls firing of ignition coil(s), may have anintermittent open in circuitry that causes loss of spark, hard startingor sudden stalling, usually when hot) Bad ignition coil(s). Ignition coil creates high voltage to fire thespark plugs. On engines with a distributor, a bad coil will preventspark at all the spark plugs. On engines with a distributorlessignition system or coil-on-plug ignition, a bad coil will only affectone or two cylinders depending on the application. This may make theengine hard to start, but it will run on the remaining cylinders thatare firing. Cracks or carbon tracks inside distributor cap or on rotor (allows spark to short to ground before it reaches the spark plugs). Bad spark plug wires (if wet, cracked, burned or internal resistanceexceeds specifications, can interfere with good spark and make enginehard to start). Fouled spark plugs (if the electrodes are contaminated with deposits,spark may short to ground before jumping gap causing misfires. Can makeengine hard to start and run poorly. If plugs are wet when removed, itmeans they are not firing or engine is flooded).

Remove distributor cap have someone tap the key while you watch the rotor inside the distributor if it does not move that is the problem then it could be the gear shear pin has broke or cam is not turning distributor.
If you are not getting spark at the coil, then you're coil may need replaced. Also, pull the distributor cap and check the cap on the inside as well as the rotor. If you have not recently tuned up, then I suggest replacing the spark plugs, spark plug wired, (coil wire should come with them); the coil; distributor cap and rotor. When doing the spark plugs and wires, start with one, and replace the plug, then the wire for that plug - do this one at a time - do not take them all off at once, unless you have a book that shows the firing order. (Having a book for any vehicle is a good idea). Please let me know if you have any further questions, or need further assistance.
In addition, if this does not suffice - replace the starter relay. If this is blown, the car won't even turn over.

Lets start off like this there is 50 different things that can cause these issues but will start with the simple things in a list. So here it goes
1. bad spark plugs (carbon fouled,fuel fouled,oil fouled, heat glazed, or just worn out rounded electrode's ) 2. spark plug wires (there is no simple way to check this but there cheap and easy to try) 3. distributor cap & igniton rotor (or coil pack if so equipped) could be corroded carbon glazed heat glazed again thought both rotor button and distributor cap are cheap and easy to change. If it is a coil cheap to and just as easy on both this is were plug wires connet to on the oppsite end of spark plugs. 4. coil pick up (this sits underneath distributor cap and rotor and is cheap and easy to fix aswell) 5. clogged air filter 6. bad pcv valve 7. bad egr valve 8. bad fuel pressure regulator 9.bad fuel pump or clogged strainer 10. vaccum line leaking or off
I know with all that being said may sound overwelming but most are easy to fix and cheap this is what i would so first do a good tune up this includes new spark plugs , plug wires, air filter , pcv valve,fuel filter distributor cap and rotor (or coil pack if so equipped ) .
That will most likley fix your problem
If it helps please leave 4 thumbs up and if it works a testomnial thanks
In reading your issue at hand not having no spark there is only a few things that can cause this being that its a 1988 car i will list below what you need to go over and check.
1.spark plug wires 2. distributor cap 3. ignition rotor 4. coil pick up 5. faulty distributor
That being said most are a easy and cheap fix plug wires run about 20-35 bucks autozonesduralast brand , distributor cap runs between 7-18 bucks , ignition rotor 3-8 bucks , coil pick up about 15-30 bucks all at autozone.
Now there is no real way to tell if there bad but a good examination of the distributor cap and rotor should tell you corroded inside cracked worn down.
i would start with distributor cap , ignition rotor, coil pick up if the car starts after this replace spark plugs wires. If that does not fix it most likely you distributor is faulty itself.
i hope it helps if so could you leave me so 4 thumbs up feedback thanks so much
Needs to check and make sure timing belt is not broken, if that checks good, more then likely it's going to be the ignition control module, sit in the distributor, also have him ohm ignition coil. but more then likely if timing belt is good, ignition module.
If you have spark at the coil then you have a good coil. You can't measure Ohm at a spark plug since it is alway open at the gap. But you can OHM measure a spark plug wire at both end. If you have nothing mean your wire is bad. You can swap one more wire to confirm a bad wire. If your wire is not bad then I recommend to replace both rotor and distributor cap. Good luck in locating the problem.
First check the primary (12 v ) to the coil.Next the coil center wire must have a high voltage spark to the distributor cap, if not then your coil is the problem.If you have a good sharp spark from the coil proceed to check the distributor,capacitator,rotor, points (or electronic ignition.You check the spark by having someone crank the engine while you hold the wire far enough away for the spark to jump to ground.Be careful as this is high voltage like a stun gun.Good Luck.
Well, if it was running prior to your replacing the plugs, then somewhere you went amiss. Check the firing order. If when you crank the engine over and it pops and backfires then you have a few plug wires mixed up. Other than that the other item to check would be the rotor button in side the cap. Is it lined up correctly or broken? Good luck.
