Yamaha Superjet/Waverunner No Start / No Spark - Bad Start/Stop Switch?

- เผยแพร่เมื่อ 18 ต.ค. 2024
- Yamaha start/stop switches are notorious for causing no-start problems due to no spark. If your Superjet or WaveRunner cranks but won't fire or start, rule out the start/stop switch first. It's quick and easy!
Replacement start/stop switch: Yamaha EW2-68311-01-00
New start/stop switches can be purchased here: www.yamahapart...
Note: now that I've replaced my switch, the engine only cranks when the lanyard is attached. With the lanyard removed, nothing happens when I press the start button. When I had a bad switch, the engine would crank whether or not the lanyard was attached.
Worked perfect! It was getting water shy. It was hard to start and consistently started the rest of the day when it got going, but just got harder and harder to start. This fixed it!
1990 Yamaha waverunner.
Thanks for the comment Will - glad it helped!
🎉 I had this exact same issue on my 1992 VXR 650. Mine actually would not crank over. It was just as if it stopped electrical work altogether.
I’d almost rather have that problem…when it cranks but doesn’t start you begin wondering about compression, carburetors, and other things that aren’t related to the actual problem!
Thanks for the video this appears to be my issue and an easy test to perform. Not necessarily an easy diagnosis but glad I came here. For my ski I am still able to see spark on the spark plugs which doesn't make sense to me. Not sure if it's only a partial spark if that is even possible. 1990 SN superjet.
Hey Chylez. If you're seeing spark with all electrical connectors connected while cranking, this video won't help you. Assuming you've got good compression, your problem lies with your fuel system. Maybe time for a carburetor rebuild?
I had the same problem on my 96 wave venture but happened right in the middle of going for a rip. Just died all of a sudden. Weird that it decided to do it at that time. But I just cleaned out the kill switch and it was fine
bro just happened to me yesterday flying on the lake and dead outta no where 😂😢
Awesome
Thank u
it worked i was gettin ready to put a stator in
Glad it helped!
my 96 gtx seadoo does this. the engine would turn over with the stareter but no spark. took apart the start stop switch and found it was fused together and corroded. weird that it cranked but wouldnt start.
Definitely weird, and exactly why I wanted to get this video out there! Glad you got it figured out!
Great tip help me a lot thank you
You got it! See you on the water!
My 91 sn 94 fx1 and 93 blaster all had that and would not start without the lanyard in. I still have my blaster and just went to check to make sure and it will not crank unless that button is pulled up. You must of had a faulty switch haha
Ok good to know! Yeah for sure, mine was acting very weird.
@@unstuckchuck yeah. I think I'm having stator problems. That's how I found your video haha. I broke my lanyard mid summer and had to hold that danm button up all the way to shore lol. I was like I don't remember it cranking unless I help up that switch. My 91 suoerjet I had it zip tied up and just had it die when I left off the throttle haha
how do you disconect
There is a little tab that I’m touching with my thumb at 0:42 that you’ll need to press down while pulling the connector ends apart.
I have a 96 waveraider 760 and I'm having trouble locating this plug. could it be inside the electrical box? I can't even fiqure out how to get that box off. I'm getting nothing when I put my key in and try to hit start button. It started a few weeks ago but then I washed the inside of the engine bay over the weekend and it's not doing anything. maybe something got wet?? thanks for any help
Hey Chris, given that your starter doesn't engage you've got a different issue than what I describe in this video. That said, I'd try jumping the starter relay in the electrical box if you get that open. (The starter relay is the roundish black plastic thing with the two thick red wires bolted to it. Jump it by touching a screwdriver or other conductor to both terminals.) If your starter engages when you do that, you know the problem isn't the starter but instead either the starter relay or the start/stop switch or wiring. A wiring diagram for the starting system can be found on page 141 of the Waveraider service manual accessible here: www.mediafire.com/file/m23nhrffo1d/Yamaha_Service_Manual_WaveRaider_94_to_97.pdf/file
Hello how’s is it going. I have a 1996 Yamaha wave raider 1100. Bought new batttery and no power replace the starter solenoid and no power I unplugged the black and white wire and no power. So I jump started the solenoid with a screwdriver and it turn on. What can it be the problem no starting with the start switch. Thank you
When you jump the solenoid does it crank or actually start and run?
@@unstuckchuck when I jump start it it actually starts and it runs
Will not start without the lanyard in place, but in place it does start. but to pull the lanyard does not shut it off, nor does the stop button turn it off. the spring is fine, clean. i was wrong about what i said yesterday. how about now, any help>
First, make sure all electrical connectors for the start/stop switch are connected and you don't have any broken wires between that and the ebox. If no problem there, your start/stop switch may be faulty. Go to page 7-9 of the service manual at the following URL for a continuity chart to check your start/stop switch with a multimeter. A wiring diagram for that system is shown on page 7-8. www.mediafire.com/?d09ct9u1plmros1
I have a 96 waveraider and it starts just fine but the stop button and lanyard won't stop the motor even replaced the switch any ideas on where to look or possible problems?
Look for a disconnected connector or break in the black/white wires that come from the start/stop switch as shown in this video.
My ski cranks but no spark will not start. I tried to unplug black and white wire connector. What do you think?
Do you get spark when the wire is unplugged? If yes, then the start stop switch is bad. If no, then you have another electrical problem.
I purchased a new switch simply And same issue. The Ski cranks and turns over just like normal but no spark. The interesting thing about this the ski was running just fine on the water and just stopped.Like the Killswitch was pulled.. What should I look at next?Thank you for your help
@@jonathanjohnson4276 ever figure it out
I just bought a 91 Waverunner W500. Mine won't crank at all with the start button and lanyard attached. Cross out the solenoid and it cranks, then starts and runs great. Start button possibly corroded?
What do you find if you disconnect the black/white pair of wires as I describe in the video? If it starts when those are disconnected then the problem is somewhere in the start/stop switch. If it doesn't start with those disconnected then your solenoid is probably the issue. Good to hear that it starts when jumping the solenoid. That rules out any corroded connections along the big starter cables at least.
@@unstuckchuck I'm going to mess with it today. I'll try and find that black/white pair and unplug it. Thanks dude!
@@TheVenom8343 sure thing. Good luck
I have a 1997 Polaris, SL 700 no spark, but if I press and hold the bilge pump button while starting I’ll have spark any idea what this could be?
Hey Hunter - to be honest I'm not familiar with this model's electrical system. I did learn that SBT makes an ignition upgrade kit (link below) for your ski...it's expensive but it may help to learn why they sell it. www.shopsbt.com/jetski/polaris-ignition-system-update-kit-slh-sl-1995-04.html?gclid=Cj0KCQjww4-hBhCtARIsAC9gR3Y83UJuPWAYJpmtOWWcG7GQdAASvd4HN3hgP-n9_VglLsw1CmwBAEYaArtwEALw_wcB
@@unstuckchuck thanks!
Disconnected it and it still only cranks won’t start whatsoever on my 97 gp760 waverunner
Ok. Time to pull the plugs and verify you’ve got spark. If you do, then check fuel/carbs. If you’ve got both of those, check compression.
@@unstuckchuck got it working now only problem is now it won’t start without fluid only using a can that has half ether half oil idk if that will harm it as bad as full ether
@@unstuckchuck spark plugs were shot that’s why it didn’t work
Where is the starter location? Helping a friend
It sits under the exhaust manifold (port side of engine)
Thanks
Would this help me if my Yamaha 99 waverunner GP800 isn’t clicking or starting ? No clicking at all
I don’t know, but it’s easy to find out - just disconnect the connector for the black/white wires as I mention in the video. If it clicks/cranks/starts with the connector disconnected but not with it connected, the switch is the problem.
@@unstuckchuck thank you for the reply. I have found the white and black cable however I can’t find where to disconnect from. Both sides seems to connect to hoses.
@@Dan-YullC Locate your electrical box and then trace the wires from there. You may need to remove them from the "hose" or flex conduit that covers them to locate the connector.
this worked and it cranks when i unplug it, but the stop button doesn’t, so i have to plug the wire back in for it to stop. how do i fix?
1990 yamaha wave runner btw
New start/stop switch.
How do you get that connector apart??? Please help
If you look at it from the bow or switch side. Orient it so that the small tab inside is on top. Lift up on this tab and then pull gently on the wires on the bow side. The smaller bow end of the connector should then slide out of the larger stern side.
Hey ours won't crank zeeeeeero power . Continuity neg post battery cabled . 1400 ohm . 1989 1200 waverunner
1400 ohms across the starter? Not sure what "good" values are for that but may be worth pulling the starter and bench testing it. These starters commonly fail due to water intrusion over time.
@@unstuckchuck no battery neg positive bro .
@@unstuckchuck we got it started I'm genius. Just search utube you will find. It's a fuse we fixed it. Still nothin nota. No screen even then . I saw . ........... Push mode 15 seconds. Hahahaha screen on ask for code . It I put AAAA. Hahahahahaha bam it runs . The owner cried I croedhahaha we are in west Africa a Vancouver, me. Him Seatlle . Hahaha. Now we ride
sooooooo inthouseaskick
