Probably your CDI they supply the electricity to the plugs.

SOURCE: I have no spark at

1. The on/off button on the right switch housing could be off. Turn it on
2. The on/off button could be faulty.Take apart and use test light to see if the switch is working by turning it on and off and see if power crosses the connection with the switch on
3. The ignition switch could be faulty. Test with test light to see if your getting power to you coil
4. The stator provides the power. Use Ohm meter, black to ground(green), and red to white wire, then red to yellow wire. the reading should be the same for the white and yellow wire. example: 288 and 288
5. The signal generator/pulse pick-up, send the signal to the cdi. Use ohm meter , black to one end of the wire and red to the other end of the wire, should read 000. if anything else the wire is broke.
This wire is usually black with a red stripe or red with a black stripe.
6. The cdi sends signal to the coil, to fire on time and advance and retards the fire as the motor revs and decelerates. Can be tested but not fixed, must buy a used or new one.
7. The coil provides the spark. Easiest to put a working coil on and see if it fires, if it does, then your coil is bad and just needs replaced.
8. Make sure if its on the kickstand that it is in neutral. Its a safety switch.
9.Make sure you have a good battery.Most local auto parts stores load test them for free

could be a bad wire or plug cap they have a resister in them, each coil fires two plugs, so if the other one works off that coil the cdi is probably ok.
pull the caps off and check the resistance from the plug wire back to the coil ground, they need to be the same, the wires are moulded into the coils so if one has high or open resistance-new coil required

SOURCE: my bike is cranking over but wont start.. iv put a

have you checked that you have compression? remove the spark plug and put you finger over the hole and try starting the bike your finger should be pulled into the hole
and how old is the fuel? it starts to break down after a few months

2004 chrysler van 3.8 motor replaced coil pack still doesnt fire number 4 cylinder

If the coil pack has a four wire connector, one wire is primary voltage, the other three wires are ground, one ground for each coil, one coil fires two spark plugs. If problem with coil or ground, you would lose spark for two spark plugs. Did you visually check for spark, everywhere? What about the spark plug wire or the spark plug, itself?

What can i check for, i am not getting fire to my plugs

1. Check for power to coil(s) when ignition key is in run position.
2. Check coil(s) have continuity to chassis ground.
3. Check coil wire continuity to spark plugs.
4. Check for some resistance between coil spark plug wire connection and chassis ground - should not be 0 ohms but can be very low and should not be be open (infinity) either.
5. Check for no continuity between coil(s) (12V) power connector & spark plug wire connector.

Depending on type of ignition, other things can be checked, but need to know vehicle, engine, ignition type, & etc.

89 pickup 22re. no fire on no. 1 cylinder

It could be a fault in the wiring for #1 injector, or a defective spark plug in #1.

All four injectors have a hot wire to them with key on, the same black with red stripe wire is spliced to all four. Check if #1 has this hot wire with key on. The injector ground wire for #1 and #3 is a white wire with red stripe. These two ground wires splice together before the ground wire enters the computer. So the computer pulses #1 and #3 injectors simultaneously. (Injectors 2 and 4 have a similar set up, with a white wire being their ground.) If you have a hot wire to #1 injector, but no pulse on it, but #3 injector is pulsing (putting fuel into the cylinder), then the ground wire for #1 may be broke before it connects with the #3 injector ground. The wires and the splice are probably buried inside the engine wiring harness, so one could check for continuity on the ground side for 1 and 3. With key off, use an ohmmeter and check resistance between the grounds for #1 injector connector and #3-check on the harness side of the injector connectors-it should show low resistance-low ohms value. If very high resistance is shown, trace the ground wire from #1 injector.

92 civic engine stalled while driving; fuel pump works; replaced all plugs seeing some oil on old ones. only one plug fires; is coil still working? or the distributor? haven't checked fuel...

Check the ignition distributor cap and clean the electric contact points it might be already dirty.

if one has a spark that means your ignition coil is still okay. Remove the whole cap and check the inside part and clean it, use emery board.
Check also the high tension wires( spark plug wires ).
Hope Fixya helps you!

My generator will not start I don't think I am getting a spark?

To check the spark you need to remove the spark plug. Then reattach the plug wire to the plug. Next, ground the plug to the engine. Finally, pull the start cable and check for spark. Remember not to pull the starter without the plug being grounded or you can ruin the ignition module.

My ford focuskeeps missing if sparks on 12 AND 3 BUT NO SPARK ON 4 CHANGED PLUGS AND LEADS CAN YOU HELP PLEASE

This has a coil pack and four spark plug wires, correct? If so and you have replaced the spark plug wires and you don't have any spark out number four but you have spark on number one than you have a bad coil. You can remove the number four wire from the coil start the engine. Use. Test light connected to ground and place it near the opening in the coil that the spark plug wire goes into. You should see a sharp strong snappy spark. You may find that you have to hold the test light really close to the metal part inside the oil tower to see any spark. If this is the case you have a bad coil. Be careful when checking for spark. There is between 30 - 40 thousand volts generated but the merge is extremely low. If you get zapped it's going to tickle. Bit but it won't kill you. Good luck and let me know what you find.

I checked battery,alternator,and fuel pump,still wont start.?

is the engine getting any spark, disconnect 1 of the spark plug wires and ground it, and have someone crank the engine over to see if it is getting spark, if so, i would check the fuel pump relay in the fuse box under the hood on drivers side. if you didnt get any spark from the plug wire, then i would check the coil, it could be bad since you weren't getting any spark.

make sure spark plug is tight,if that is not it pull plug and ground it to see if you have spark,also make sure plug is not fouled,then check ignition coil,that if there are two primary wires make sure there are connected and power is getting to them.if you have just one wire coil is internally ground check for insultion breakdown also make sure your plug wire is good

Car wont start. I have gas, pump works, i just dont have spark, coil works, rotor turn .

check spark plugs or spark pug wires. These are the most common issues with no spark. 2. check all fuses. 3. check ground or battery cables. If ground is bad it can cause a no spark. Motor turns? or ROTORs TURN? If motor turns your getting spark.
