l the battery goes flat, there is a spark on the spark plug but the fuel small container under the handle bars dosn’t seem to be full (its about 2″ square) also i think i may have damaged the starter somehow because when i tried to hose pipe flush its started making a buzzing noise instead of turning the engine, is there a solonoid or something rather than stripping the starter apart? thanks j

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. :
There could be several reasons why a WaveRunner is not starting. The simplest and most common fault is when the shut-off clip is not properly attached or the tank is empty. Other common reasons could be electrical issues like malfunctions with the battery, spark plugs, fuses, or wires.
Spark Plugs
Spark plugs are often the problem if your jet ski engine turns over, but doesn`t start, especially if you have a 2-stroke jet ski. Take the spark plugs out and examine them to see whether they`re wet or dry. If they`re dry and light brown in color, you have the correct fueling.
A misfired engine can be caused by a number of mechanical problems: Defective or worn spark plugs. Water inside the spark plugs. Old or water-contaminated fuel.
Jet ski batteries notoriously die due to inactivity. If you don`t use your jet ski often enough, the battery will begin to sulfate. Over time, excessive sulfate buildup can cause your battery to take longer to charge, become more susceptible to overheating and lead to complete failure.
Limp Mode is a slow-riding mode that becomes activated when the ski detects a malfunction. It allows you to ride back to the dock with reduced engine power.
Bad Spark Plugs
If the engine holds compression well, and the fuel system is working correctly, but it still won`t start, that tells us that your car`s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine`s cylinders. It`s the resulting explosion that actually powers your car.
Check the spark plug
Inspect the spark plugs for damage to the insulator tip, boot and upper and lower insulators. Next, check the spark plugs for signs of fouling. A fouled spark plug occurs when the plug isn`t burning fuel normally, leaving damage to the plug which can cause the engine not to start.
This is because a poorly maintained and serviced engine and other parts wear out much sooner. Every owner`s manual strictly outlines required service intervals. Beyond regular service, jet skis need to be winterized in most cases. Additionally, every owner should carefully check their skis before and after rides!
A jet ski not starting is most often a dead or weak battery. A bad starter relay can also be another reason for a jet ski not starting. Usually, when you hear multiple clicks from your jet ski, it`s a bad battery and if it`s one click it`s a bad starter relay.
Most manufacturers produce machines designed to last around 10 years; at 30 hours a year, the approximate average lifespan of a PWC would be around 300 hours.
Conclusion. Today`s jet skis are really big and heavy, and at first glance, they seem like extremely massive vessels. But it`s good to know that they`re not designed for wave jumping, which means the dynamic forces incurred by the jumps can damage the hull or even the engine`s mounts, which can lead to serious problems …
In the event you have a completely dead battery do NOT attempt to jump-start the battery with your car battery or even a jump pack. This can cause extensive damage to your jet ski`s electrical system and is not recommended.
A flipped PWC won`t sink because its hull is designed to float even if it takes on water. There could be potential damage to the vessel if certain parts become and then stay flooded though.
In the event you have a completely dead battery do NOT attempt to jump-start the battery with your car battery or even a jump pack. This can cause extensive damage to your jet ski`s electrical system and is not recommended.
If your Sea-Doo turns over but won`t start you may just need to refill the tank. Another issue could be if the gas is water-contaminated or went bad over time. In this case, you have to siphon the fuel from your Sea-Doo and refill it with fresh gas.
In the event you have a completely dead battery do NOT attempt to jump-start the battery with your car battery or even a jump pack. This can cause extensive damage to your jet ski`s electrical system and is not recommended.
No! Never run the motor of your watercraft out of the water.

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?

I have a 1996 yamaha wave venture 1100….ran greatsat for 2 yrs..started but only ran for spray into carbs….drained fuel started and ran good. Started about month later and would only run as long as primed with starter fluids…checked fuel filter(ok)…fuel flow to fuel pump ok…output of fuel pump appears ok….but engine will only run as long as starter fluid/gas is sprayed into carbs. I don’t think it’s the carbs as it ran great a month ago…now it’s starving for gas flow….so it appears to be a fuel delivery problem…what would be the sequence of tests up to tearing into the carbs? is there a fuel filter inside the carbs? remember it fires off great when primed…until the fuel spray is consumed…
ANSWER : Check the on/off/reserve valve

Cannot turn engine over to start. Ariens 924 snow blower
ANSWER : Pull spark plugs and see if it will pull over if not fuel may have filled the crank case drain & refill to proper level (starter is stuck in lube shaft & movethe gear up & down by hand to free up)

I have a 2001 Yamaha XL700Z Waverunner. The compression on both cylinders is about 120, it starts and runs fine – dry. Won’t quite idle, but I can start it and rev it up fine (for a short period, of course). However, as soon as it gets in the water, it will barely run – it will start and sputter and you cannot get it to run more than a few seconds or rev up. Take it back out, let it dry, starts & revs fine. It is not getting any water in the casing that I can tell, its almost as if water is getting something wet through the cooling system that I cannot see?
ANSWER : Try cleaning the carbs and the fuel lines, filter

3 year old Toro Z4200 time cutter Z, 19 HP Kohler, engine runs great, new battery, new solenoid, with the seat sensor connected or by-passed, STILL WONT start off the key switch. Clicks at the kill relay. Would the kill relay be the problem?
Whats confusing is, both the green and blue posts on the solenoid have 14.01 volts when you turn the key to ‘start’ position. Did the same thing with the old solenoid, which is probably still good. I replaced it to eliminate that variable. It also ‘clicks’ at the fuel switch at the carburetor bowl, but that is only 1 lead (I assume a hot lead) so Im thinking that CANT be it.
Using the old hillybilly method, jumping across the 2 top posts on the solenoid, with the key in on position, it will start right up, run, drive and mow just fine.
So my best guess is this ‘KILL RELAY’ must be bad?
Any help would be appreciated, thank you !

ANSWER : These things are pre requisites for engine cranking: PTO/Blades are off/button pushed down, the steering arms are out/parked position, and you are in the seat. I think. Definitely the blades have to off.
