    so this is an external coil ? you crank motor and spark comes out of coil , but when you put coil wire on to cap , no secondary spark thru the spark plug wire correct ? then bad coil wire , cap or rotor issue .

    you didn't forget your rotor by chance , ,, or inspect the rotor for a hole burned into it .

My 81 f250 351 winsor isnt getting spark ignition module ,coil ,distributor,cap and rotor,plugs and wires all new i gapped plugs at .044 help


got +12v to the ign coil? does the coil spark if you ground the negative(-) terminal? does the distributor rotor rotate? it may be time to replace the distributor sproket and module (stator and armature). http://ww2.justanswer.com/uploads/Ovalex/2010-12-11_153049_duraspark_stator_exploded_view.gif

No spark at coil or distributor


I would buy a book with the procedure to troubleshoot the ignition system. The problem could be the pickup coil in the bottom of the distributor among other things. The module uses the pickup coil to know when to fire the plugs. The computer only controls when the cylinders fire.

Hi my name is fred i have a 1985 gmc k3500 454 no spark 12 volts at coil new ignition module change coil didnt change a thing checked fuses was driving on highway just died


Fred,
Did you check for spark at a plug wire or at the coil wire? Check at the coil wire,if there is spark there,the ign rotor is bad,very common to have the hot spark "drill" a hole thru the rotor to the dist shaft. Also check for play at the rotor shaft. Distruibtor bushings tend to go bad,making the trigger wheel hit the pickup coil,killing the spark.

Ther is no spark at the spark plugs, what are likly causes.


check fuses. The coil should get 12V with IGN key in run position. Check the pickup module inside the distributer and see that the shaft turns when engine is cranked. You may need a new ign module.If spark is good at the coil, the plugs/wires are at fault.

No spark to plugs, replaced rotor ignition control module its either the computer or the Engine control module under the hood which one?


Check to see if your getting power to the ign.control module from the ignition (with key to on position).If not ,you have an ignition problem.If there is power,it may be a bad ECM.If you can, get one from a 95 pickup that works and switch it into yours just to see if the problem stops.

No spark Power to coil New wires and new coil


Usually the ignition controll module or pickup coil. Your local auto parts store should be able to test the module for you.

1988 cherokee no power to coil


I'd try an ignition module based upon what you have already replaced. Depending upon which engine you have and what month it was assembled, You could have one of several ignition systems (seems like they were using up whatever was on the shelves) any diagrams are cryptic as to any relays used etc. I'd try that, then physically begin tracing the coil power back to it's source. Actually, the car is old enough that I might even consider building my own ignition system and discarding the junk they used when they built it! But, that's somewhat complicated.

1990 dodge b350 no spark


Yes you most likely have a ign module problem, the pickup hardly ever fails. If the truck is really hi miles repace the plug wires as well.

No spark on 1988 s-10 pickup 2.8 new plugs,wires coil,cap and rotor.ran for about 20mins and then quit,wont start


It could be that the ignition module is defective and causing this problem.If it's the original ignition module it may be time to replace it. The ignition module can be tested by your local Shucks or Auto Zone usually for free, The module when its starting to go out will work fine until it warms up, it will then quit working because the coils inside of it short out, until it cools down. If the module is completely gone there will be no spark at any time, The module is inside the distributor under the rotor held in by a couple of screws,
