SOURCE: 1996 zx11 getting sprk to one bank only

Hi and welcome to FixYa,

The voltage on the green wire must be pulsating when cranking/starting the bike, not steady. Confirm by similarly testing the voltage on the black wire on the left ignition coil. If the green still reads a constant voltage, then the CDI is faulty; to be more specific, most likely that the switching tansistor inside the CDI that drives the right ignition coil has shorted.

Good luck and thank you for asking FixYa.

SOURCE: cant get my 50cc scooter to fire up-no spark. any

  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Check the fuses.
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
  • Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
  • If still no spark, get CDI system and coils checked at the dealers shop.

SOURCE: Have 93 fxr. Starter turns

Take your battery out and have it load tested. It sounds like you have one or more cells shorting out under a load. A 12 volt battery is made up of six 2 volt cells. The output voltage and current delivery of a battery with shorted cells in it depends on how many cells are shorted and where they are located within the battery. This is the most obvious thing causing the problem. If the starter is drawing the battery down that low, it must be drawing a tremendous amount of current and it would probably be burning the battery cables with that large of a current draw. If you have 300km on a top end job with no problems, I doubt you have a problem with that. A problem in that area would have shown up well before now. Although, a fresh top end will put more strain on the starter and battery due to the increase in compression. Check the battery first.

Good Luck

SOURCE: cant get a spark

The only other thing you have to look is how the coil is charged up. Is the battery good? Is there 12v on the power side of the coil? Is the coil grounded? Are points or electronic ignition time in use? If mechanical points are in use then there is a capacitor near the points that can go bad. If there are points in use, do they open and close properly when the engine is turning over? Is the gap correct for the points? If this is an electronic controlled timing system, then check the cam or crank sensor for function and gap. That is checked with a volt ohm meter. I'm unfamiliar with your particular bike so I apologize that I can't be more specific.

My 94 fxr has no spark and the turn signal module burnt

The turn signal self cancellation module may have shorted out and that is what may be discharging the battery. Have you replaced the module?

I have a 1990 fxr. cranks but wont start

Hi Anonymous, some of the following will not apply because of your year and model, when checking for spark the CKP needs to measure the compression bump in order to send the correct signal to the ICM/ECM so always check for spark with either a third plug grounded or lift the end of the plug boot 1/2 " off one of spark plugs that are in the head. and the usual suspects are:
1. Fuel tank empty
2. Fuel supply valve turned off.
3. Fouled spark plugs.
4. Engine flooded with gasoline as a result of over use of enrichner.
5. Fuel valve or filter clogged.
6. Vacuum hose to automatic fuel supply valve disconnected, leaking, or pinched.
7. Discharged battery, loose or broken battery connections especially the negative cable at "BOTH" ends
8. Loose wire connection at coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, spark plug cable connections loose,
or cables connected to wrong cylinders.
10. Ignition timing incorrect due to faulty ignition coil, ignition module, or sensors " Manifold Absolute Pressure" "Camshaft Position Sensor" "Crank Position Sensor" "Brake Apply Sensor
11. Engine lubricant to heavy ( winter operation )
12. Sticking or damaged valves or push rod wrong length.
13. Primary cam sproket spline sheared or missing spacer.
14. Security alarm system not disarming.

No spark at the spark plugs ford festiva 94

Your next step would be to check the coil to see if you are getting spark to the distributor.the spark to the spark plugs come from there.then check your wire connections to the coil from the battery.

Hello, I have a 94 Harley FXR. I went for a bike ride today and as I was riding I noticed a noise that would come and go coming from the front end. When I got home the engine died on me and now it wont...

Check for battery voltage going to the primary side of the coil when you have the switch turned on. If you don't have any voltage, you won't have any spark either. You may have to disconnect the small wires to check for the voltage.

You can test the coil using an ohm meter. Disconnect the small wires and put your meter's function switch in R X 1 position. Touch the meter leads to each of the primary coil winding posts. You should read between 2-3 ohms.

As for the noise from the front end, I don't have any idea. You may want to pull the headlamp and look inside the there. I think the FXR is like a Sportster in the fact that most of the wiring is in the headlight assembly.

Good Luck

No spark wont turn over

Possible failure of either crankshaft or camshaft sensors. Have you run a scanner on your computer to see if it points to anything? Good luck!

94 royal begis to cut out, chugs at about 55

Replace the spark plugs and wires along with a distributor cap and rotor. Be careful to leave the old wires and plug wires connected to dist.cap, just remove dist. cap from the distributor and lay aside with plug wires on it then install rotor then new cap and proceed to replace each wire for cap and spark plug one at a time so you don't mix up the spark plug wire firing order. Cap laying to the side is used for reference purpose.

I cant get it to start i replaced spark plug

Does the new plug spark outside of the engine? Put the base on an unpainted part of the engine with the plug wire on and kick it through a few times. Does this engine require a battery to run or is it a self-contained ignition system? Remove the fuel tank and check for loose wires or other parts. If it requires a battery, check the connections at the battery for corrosion or looseness. Is the battery charged?

Riding down the freeway on my 1985 FXR, it was 115 degrees, bike stopped running. Have gas, don't have spark at plugs. New coil. New battery. New wires.

lotta possibilities....likely something vibrated loose. i'd start with something simple. after u check electrical connections and fuses,,,,, is the ignition module black lead secured to the frame ? all coil wires secure ? Pull the key ignition....check connections/ crossed? secure ?
