How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
If you see a good spark at the coil, but not at the spark plug, then the problem may be caused by either a bad distributor cap, rotor, or carbon point and/or spring, or plug wires. Look down in the spark plug tube. If you see the spark going to the tube, the boot is bad.
A Bad Crankshaft Position Sensor
The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.
Will a bad rectifier not give spark to the spark plugs? John Talley: That`s typically not the way it works. The rectifier is just in charge of converting an AC signal into a stable DC voltage. So it shouldn`t have anything to do with not giving a spark.
The starter will not have any impact on the engine`s ability to produce spark. There are a number of issues that may cause an ignition system to not produce spark. A bad crankshaft position (CKP) sensor (on engines that do not have a distributor), or broken, loose or corroded wires from the sensor to the PCM.
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
Incorrect timing is the most overlooked and misdiagnosed cause of a no-start. Perhaps you automatically think of ignition timing as the position of the crankshaft when the No. 1 plug fires. While this is important, it isn`t the only timing condition that can influence a no-start.
As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
If the CDI unit is faulty you can get a weak or intermittent spark or no spark at all. This translates to poor running or no running at all.
With a poor ground the starter ring return path may not allow adequate amps to return to allow a starter to reach the torque and speed to start. Normally, however, with a well tuned car and cranking, the engine will fire right up. Weakness, though, and it may not start.
stalling: a failing ignition module can occasionally prevent the engine from getting spark, causing it to stall. 4. car won`t start: an engine needs four basic things to run: fuel,compression, spark and exhaust. if the ignition module has failed completely, the vehicle won`t get spark and won`t start.
Ignition Control Modules fail when they overheat. The most common symptom of failure is a no-start. A failing module may give other symptoms, such as engine stuttering and stalling, before it stops working.
The ignition relay is one of the most important electronic relays found on modern vehicles. It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle`s ignition system, and some of the fuel system`s components.
The engine will not start
If the main relay is not supplying the engine computer with the power it needs, then the engine will not be able to crank and run the right way. Failing to get the main relay replaced will usually lead to the car being unusable.
Make sure the battery is working properly and fully charged. As the battery level decreases, it loses the ability to heat the coil properly, thus leaving you with less smoke. If the battery you`re using is old, you might need a replacement– especially if you are noticing that it is no longer holding a decent charge.
The battery, a generator and a more complete vehicle electrical system provided a relatively stable electrical supply to the ignition coil.

Turned poulan pro 42 inch 18.5 HP Briggs and Stratton mower off after 1hr of use to move a board I was about to mow over. Tried to restart it but it just backfires. Removed spark plug and it looked fouled. Cleaned it up but when looking at spark it is orange in color. Bought new spark plug and now get white spark. Installed new spark plug and it still backfires. Plug is wet with gas. Any suggestions?
Check the valve clearances and especially the inlet valve to make sure that it is not riding (staying slightly open) B&S are notorious for valve problems as most of their motors do not have a valve adjustment on them, the valves stems have to be filed/ground down to get a clearance. Somewhere between 0.010 to 0.015″ is near enough for the inlets and about 0.005″ more for the exhaust. It is not critical.
I have the Intex Sand/Pump pool filter Model SF 20110. It’s been running real great for the last 4 months. However recently it has been tripping the internal overloads and I have found the pump motor to be very hot when I put my hand against it. I have tried several different solutions, such as a level ground platform that was clear of any obstructions, made sure that the motor vents under the motor was clear of anything that would prevent air flow. I used a non electrical type of lubricate on the impeller. When I would turn on the pump the rotor would not turn but only would hum very loudly and then slowly begin to turn. I also noticed that the motor’s rotor shaft would not turn to freely due the tightness around the rotor’s shaft. After using the lubricate the shaft would turn a little easier. I used an amp meter on the incoming voltage line and the motor would run at 4.5 amp. And yet it still overheated and tripped the motor overloads. I can only think that the motor is still not getting enough ventilation. I have check and cleared all the incoming lines and found nothing block the pumps input or output lines. Any suggestion?
I just looking into this issue my self. The pump cools itself by a internal fan, which is run by the motor. Well I took the housing cover off to find out all the fan blades have broken off and were setting in the base of the pump. Once you remove the fan blades from covering the air intake, it might be fine. I will find out my self once summer gets here.
Turns over no spark I changed cdi an coil still no spark
Have you checked ground leads and fuses ?
The Bike Technicians Tactic Phase1 An electrical inspection on the bike should produce results. First, the bike battery powers the entire lightening systems mentionable as ignition, meter readings, head lamps, signal indicators. However, the battery provides the power supply to several entities though also significant is the fuse box containing circuit protection coils. Inserting the bike key into the ignition to perform start mode displays the capacity power circuits. A charged battery should display an indication in the meter reading area also known as bike dashboard grading. A malfunctioning start mode on inserting key in ignition may be traceable several locations on the electrical circuits. Attempting to repair the electrical power of the bike usually requires batter power power test kit. The test kit ascertains the battery power making possible progress to the remaining electrical circuits. Test kit also ascertains the fuse box circuit functionality either with fuses still intact or extracted allowing for the next progress level. An observation tour of the bikes electrical wiring kits from battery hold through fuse box compartments to each lightening display area either headlamps, indicators, and meter reading should produce results of any visible damages that may require repairs after the electrical inspection has been performed. Once any faults were observed on the electrical channels, repair mode is the next level. A dull battery either may have been depleted completely of durational capacity requiring another for replacement. Alternately, a depleted power supply due to prolonged storage may require charge functionalities. Usually, a device capacapble of restoring a battery of electrolytes is resorted for charger ability. The type of battery may require constuents either liquid cathode replenishment in the battery entrapment area prior to charging feature is assumed with electrolyte machine. Once the battery has regained full functionality makes way the next repair task. The fuse box may have simply required replacement fuses either as missing or burnt out. A fuse box usually contains additional spare for replacement functionalities. An alternate arrangement at acquiring fuses on the auto mart may replace the burnt devices. The next electrical task is wiring fixtures achievable by mending broken cords with appropriate electrician’s tapes else malfunctions may remain. Alternately, a worn-out electrical wire is replaceable by acquiring the entire extension lengthwise between significant areas. The last remaining electrical units are lightening indicators consisting of bulbs or luminescent displays reflectors. Observe the blub areas either by loosening covers to inspect for observable burnouts else the entire electrical circuitry is ready for functionality observations with separate entities. Engine Technicians Tactic PHASE 2 A bike engine inspection includes observation for indications of malfunction. Any fluid residue is indication of problem areas. Where oil leaks usually requires engine block inspections. A bike engine consists of an entrapment compartment where mechanical combustion takes place. First, the entire observable block consists of an external coating known as engine bloc housing internal component of pistons, rings, and fastens known as cylinder heads. A bike engine has every component embedded within requiring technical expertise to achieve an inspection. Once deciding on the engine task requirements, acquire a tool box with the appropriate componements as first requirement before engine works is commence able. Second, the bike may require an area environment as workshop requirement to attain engine inspections. Third, bike engine are least bulky compared with vehicle engines however assistance would complement the inspection phase. Prior to inspecting the bike engine, a strap mechanism has to be assumed to achieve expert maneuverability also as safe precaution. Unless parts hinder maneuverability at engine locations, the only removable components should be the engine. First, start with disjointing the spark plug cables to acquire accessibility to plugs imbedded on the cylinder heads. The plugs require tools to loosen thereby exposing the combustible area. Once the spark plugs are exposed, two alternatives are likely. First, a spark plug may have gathered rust residue only requiring cleaning to attain regular capacity. The pin area of the spark plug may have been twisted due to overheating and slight melting dislocation. Usually cleaning the residue from old plugs may simply expose the ignitable capacities. However, an observation of twisted plug pin may require twisting back in place to achieve full ignitability once bike engine starts. A bike engine bloc has the pistons as combustibles or blasters of fuel gasoline. The rings perform as strap fasteners whenever the pistons move about combustibility. Usually, the engine entrapment components would have collected residue requiring clearing. Also, pistons together with rings may require replacements either as worn-out due to prolongs tasks or overexerted biker features.

No spark to spark plug
Try checking the coil
Sled has no spark have changed stator,coil,cdi, looked for broken wires, did not find any, still no spark, sled is a 1993 arcticcat, need help to get spark
Have you checked the kill switch maybe shorted out inside,
I,ve got a Kawasaki super sport xi (jh 750-b) it hasnt been started ffor a couple of years so its my job to get it going so i’ve cleaned out the water jet (cause it had some big stones in) got some new spark plugs and tried kicking it over, there NO SPARK now. And also i could turn the propeller and it wasnt turning the engine, is that true. My friend said it had sucked up a stone and snapped somekind of bolt is this true. If its the coil packed buggered thats why there no spark where can i get another…. Many thanks carlie
Two problems if there is no spark it could be several things, the prop not spining is normal if you sucked up rocks, it’s design to do that to save the motor. It’s a rubber spacer. I’m parting out my 750 xi ss. Let me know if you need parts [email protected]
