Have the system scanned for codes. Remove the plugs and check for fouling. A fouled plug can indicate a bad injector or bad piston rings. There are other plug conditions that you need to pay attention to as well. Find a chart in any good manual.
There is no one "solution" for your problem. Could be from a bad temp sensor, bad O2 sensor, manifold air temp sensor or something else. That's why testing is so important.

Testimonial: "i am so sorry i apolize it was helpfull i didn't realize the rating till just now. you are doing a greal job agin i apolize so sorry"

    Thanks for the poor rating! The information I gave you is valid, learned over many many years.
    No one can give you a definite answer without actually being there and doing hands - on testing, and making a careful examination of your engine. Anyone that attempts an "instant answer" without doing that is foolish.
    If you needed more information about a specific item or did not understand the answer, all you needed to do was ask and I'd have helped with that!
    I spend time trying to help people I don't know and will never see. I share info I've gathered during the many successful years I've spent in the industry. I do this for free. Therefore a poor rating is disappointing!!!!

    Thanks for changing that...Most important though....Did you find the problem???

Why I'm not get n fire to spark plug


Hey Troy, I need year--make--model? Any applicable trouble codes?
It depends on your ignition system? If distributor ignition system, have to check distributor--dis cap--rotor--spark plugs--spark plug wires and electrical circuits. If dis ignition, no distributor, but a coil pack, also check electrical circuits. You could have coil on plug ignition or coil near plug ignition. I need more info?

I would look into replacing the coil even though it is sending spark it might not be enough and I would go through and just double check all my wires as well as the firing order because if it's off just a little it will make the car run rough

I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

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 !

Want to check pickup assem in dist.


Fouled spark plug? Bad wire? Rotor / cap new? Check those things out, wear a thick rubber glove, take the wire off the non working plug, put a screwdriver next to the wire (while car is running) and see if a spark is made. If it is, your plug is bad. If no spark, replace wires. Still no spark? Change your rotor and cap. Still no spark? Ignition module. Following those steps will save you some green.
