What should I do if there is no spark in my spark plug?
Holding the loose plug by its ceramic insulator, make certain the plug’s metal base is well grounded. Then, have someone bump the ignition switch or kick starter while you observe the plug’s ground electrode. If you see a blue or yellow spark bridge the gap, then you should have adequate fire to ignite the fuel/air mixture in that cylinder. If not:
What to do if your light bulb has no spark?
If not, the switch may be broken or may have lost its ground. 3) Once you have determined that you have power from the switch to the coil, use your multimeter or bulb tester to ensure that the current leaving the coil is reaching the spark plug cap.
What to do if your ECU is not getting power?
If you’ve established that you’re not getting a spark at the plugs, the next thing to do would be to work back – so test the coil packs. Pull out the plug from one of the coil packs and see if it is getting power, has a good ground, and has some kind of signal coming from the ECU.
What to do if your motorcycle has no spark?
If not: 2) Be certain the motorcycle is turned on. That sounds simple but ignition switches can fail. Plus, on many newer models of street bikes, the motorcycle’s anti-theft system must receive a specified flow of juice or the engine will not start.
Can bad spark plugs cause a car not to start?
Starting Trouble. Faulty spark plugs can cause the car to exhibit starting troubles. Worn out plugs does not produce sufficient sparks, which is needed for starting the engine. This results in the engine to stall and fail to start quickly.
What causes no spark at plugs?
A grounded kill switches, faulty spark plug, spark plug cap, pick-up coil, stator, igniter and ignition coil ( you have replaced already) can cause a no spark condition.
Why is my spark plug not firing?
A spark plug won’t fire properly if its electrodes have been worn thin, if they are covered with combustion deposits or if they’re wet. If the plug has seen many hours of service, the electrodes may just be worn out, and replacing the plug will restore normal engine operation.
How often to replace spark plugs in the engine?
Eventually, it becomes so worn that it doesn’t create as much (or any) electric arc, which has a direct and immediate effect on your engine operation. If you check your owner’s manual, you’ll probably find that your automaker recommends you replace your spark plugs roughly every 30,000 miles . That’s fine if you’re using stock spark plugs.
How to know if your engine has no spark?
First Confirm Your Engine Has No Spark. 1 Disable the fuel system by removing the fuel pump fuse or relay. 2 Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. 3 Finally, Have someone crank the engine and watch for spark.
How do you change the spark plugs in a car?
When you’re changing your vehicle’s spark plugs, work on one spark plug at a time: Remove it, inspect it, clean it, and — if it’s salvageable — gap the spark plugs. Then replace it before you move on to the next spark plug in cylinder sequence order.
Where does the spark wire go in a spark plug?
To maintain the proper firing order, each spark-plug wire must go from the spark source to the proper spark plug. Therefore, only remove the wire from one plug at a time, and don’t disconnect both ends of the wire!
What should I do if there is no spark on my coil?
Remove the black wire that plugs to your coil and try checking your spark with this wire unattached. This is your kill wire. ok what should happen once disconnected? This wire will eliminate the possibility of a safety switch or a bare wire preventing your coil from producing a spark.
What are the symptoms of bad spark plug wires?
The most common symptom of bad spark plug wires is a rough engine idle. Spark plug wires are responsible for transmitting the electrical current from a vehicle’s electrical system to the engine spark plugs, where the electrical current is used to ignite the engine air/fuel mixture.
What are the best high performance spark plugs?
For the vast majority of drivers on the road today, the Bosch Platinum +4 can be considered the best all-around spark plug. The Platinum +4 achieves its high performance by employing four (as opposed to one) yttrium-enhanced ground electrodes.
Why do spark plugs need to be changed?
Oil Leaks: When you pull a spark plug out of the engine, the base should be relatively clean. If there is oil present, it means there’s a leak. Not only does that mean you’ll need to replace a blown seal, but it means your spark plugs will need to be changed more frequently because of contamination.

What’s the spark plug gap on an EZGO?
EZGO golf carts with NGK BPR4ES spark plugs typically have a spark plug gap between 0.028 and 0.030 inches. EZGO golf carts with NGKBP5HS spark plugs have a spark plug gap of about 0.025 inches.
What kind of spark plugs do golf carts have?
Yamaha G2 golf carts with an NGK BP4ES spark plug have a spark plug gap of 0.028 to 0.031 inches. Yamaha G9 golf carts have NGK BR4ES spark plug with a long reach of 14mm x ¾ inch. However, some of them utilize anNGK BPR2ES spark plug. The following are some points worth looking into if you have an issue with the spark plug in your cart.
