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.

You have problem with you timing or did you ever label all the high tension wire before you unplug it. it might be re arrange the firing sequence. 1342 firing order. And the timing position of the distributor were at original place.

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.

My car isn't firing. I changed my ignition coil, but distributor still isn't getting any spark(new wires,dis. cap,ign coil)


Without looking at the diagram on our model Is suspect the pickup in the distributor has gone bad. In the early type distributors the pickups are prone to go bad but ground the wire from the coil to the cap and remove the cap, have a friend turn the engine over with the starter for a few seconds, check that the rotor button is turning !

1988 jeep wrangler will not start


If you did check out all the ignition system and switch and everything is fine on that side, the only thing left i can see would be a faulty body ground, preventing the engine from grounding and preventing the plugs from sparking since the current has nowhere to go since it's not grounded. So check all the body grounds in that area and check for rust, or anything that could cause a faulty ground, clean it all up and try again. If it was rust, might i suggest the use of Dielectric grease, which will prevent rust from forming, but let the current flow through. Basically it's the same white grease they give you when you buy a set of new spark plug wires.

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.
