Why does 99 honda cive ex have no ignition spark?


There is no definitive test for it the ICM, or igniter. If you are positive that the coil is good and it has power at the black/yellow wire, confirm that it is hot at the igniter. Make sure all 4 connecters on the igniter are tight, they should not pull off easily. With the cap off, you should check for spark directly from the coil to ground. Rotors fail too. If everything checks out, and still no spark, the next step is replacing the igniter. Check prices at Honda, sometimes they are the same or cheaper than aftermarket.

Ignition mystery! 1994 GMC Suburban 2500 5.7 mtr. No spark to spark plugs. Have spark from coil to distributor. Have changed coil wire, cap, rotor, ignition module, and coil. have 12.5 volts going to...


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.

Sounds like you replaced alot of parts for nothing.
The pickup coil in the distributor "fires" the module which grounds the coil and the injectors.
Those components would need to be tested. The coil fires the plugs when the ground is removed by the module or the key switch.

MY HONDA DIED ON THE ROAD AND IT TURNS OVER BUT NO SPARK TO THE ENGINE... MY MECH IS HAVING A HARD TIME LOCATING THE PROBLEM...


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.

Turned off then wouldnt start ,took ignition apart cleaned up ,no spark to plugs cap,rotor ,wires good power to coil and module


If there is no spark to the plugs, but good cap, rotor and wires; then if the there is good power to coil and module, then the module or coil must be bad.

1989 GMC engine turns great , no spark at coil or plugs, had coil tested and repalced- new rotor and cap. not sure where to go next


Check your fuses (ECM) and also recheck your wire leads to the coil. Your ICM (ignition control Module) may also be bad, it's located in your distributor under the rotor. You can have that tested also to make sure it's working 100%, there common to go bad from corrosion caused by condensation under the distributor cap.
Thank you for using Fixya and good luck.

1990 Isuzu 2.6 L 5 spd. No start.. Fuel pressure is ok, not getting spark. Checked coil, ignition module, distributor, computer and coil wire. No power coming from the coil. Small voltage going into...


assuming you the coil, plugs, cap, rotor and wires are good. check the cam sensor, If you have 12 volts to the coil using a 12v light tester. The cam sensor responsible for sending info to the computer telling it that the cam is turning, then the computer tell the coil to dispurse the charge/sparks to the distributor as distributor distribute the sparks to each plugs from the rotor of the distributor. Replace the cam sensor, it tend to go bad over period of time.

Here are a couple of things that could be causing your problem. 1. Bad ignition coil or ignition module 2. Clogged fuel filter 3. Clogged air filter 4. Clogged fuel injectors 5. Bad spark plugs, wires, distributor cap and /or rotor. 6. Broken timing chain/belt. Here are a few things you can try to verify that you have a good spark. 1. Remove the distributor cap and crank the car. If the rotor turned you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. 2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module or ignition coil is bad. 3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.

Replaced entire ignition still no spark 88 305 ci


There are 3 possibilities. 1 the coil. 2 the ignition module. 3 the pick up coil. In my experience the ignition module is the most common cause. It is in the distributor held in with 2 screws. The coil and module can be tested at any parts house. Good Luck

It was running before until it sat there for a year or so now it won't start, i check to see if the wires had spark but nothing.


You didn't state what year it is, but check for spark at the coil, or coil pack. If no spark, replace coil. If that doesn't work, then you have more testing to do.
