Another thing about the ECU, they have a symbol on it that is suppose to match with the injectors. If you are not getting spark then the pick up coil needs to be checked and the gap between it and the flywheel.
TSS switch is a common ignition killer. No spark when throttle not closed all way or if contacts inside throttle safety switch are toast. Can spray starter fluid directly in spark plug hole. Pull and see if fires. Can eliminate spark if fires
I'm going to get an OEM stator and see if that helps, this one ohms out but still may not be correct! I have pulled the motor and found the temp sensor for the ECU to be way out of spec so I am going to get a new one of those as well! Thanks for watching!
Im interested in the outcome, and think you're doing awesome. You have to be close. I have an 08 Crossfire 5. I feel the sleds are pretty similar for the most part, so this could happen to mine. Best of luck. Suscribed
i found this guy's story online.........hey, just got rid of the same problem with mine, no spark then if it had spark it would run 2 seconds and no spark, i swapped ecu, timing sensor, coil, and new plugs, still nothing, so figured it was stator, so i sent mine to rm stator to get rebuilt, they charged me 180 and cost 100 shipping return and also put new timing sensor, and coil in, new plugs again, and pull the rope, still no spark.... so i find a used stator with only 20 hours onit, and put it in, still no spark,! then noticed plugs were soaked, so pulled reeds to look for broken reed, they looked good, and i look in the bottom of crank case and find it full of gas, so i venturi vacume it all out, put back together and pull rope... it runs... for 5 seconds this time and dies... plugs are dry, and no spark,, wtf now... tore wireing harness off and read contenunity between all wires end to end, they look good, put in dish washer to get hot and recheck,,, still good, put in snowbank overnight, and still look good,, put it back in sled and spark for 3 seconds, and dies.. no spark.. wtf. wiggle harness plug at ecu and unplug it a couple times, then got spark,, so i retest harness ahain, this time with alligator clips on wires, and took each wire out of ecu plug, one by one, and check them this way. bending every wire every 1/8 inch all the way to end, and looks good, !.so i start inspecting wired at ecu plug, i found the top row of wires in plug, last 3 on the right side, were dark and smelt burnt.. so i clean in muratic acid, put together, still no spark, then take them 3 out again, coat them with a cuple coats of liquid electrical tape, and let dry, then one last coat of liquid tape and shove then in theyre proper hole, push white clip on plug in, plug the harness into the ecu, and the piece of **** runs awsome,,, go for a ride, make it half a mile, and it dies.. wtf.... tow home, and i at this point wanna burn it, i then take and order a new harness , put it in, tie it up nice and tight, clean all connections, run an extra ground from stator to frame,, pull rope and noo friggin spark,,,, WTF !, im pist!, i unplug the ecu harness and slightly bend all the pins on the ecu all in the same direction, and plug it in,,, i could feel some resistance in pushing it in, it fired right up, and i rode 540km over 2 weeks, and just start to gain trust in machine again, then it suddenly died again, ... tow home, and this time it has spark, but no feul psi... so i put new pump in and shees runnin good now.. SO I WASTED MONEY ON COIL, 2 STATORS,WIREING HARNESS, SPARK PICK UP MODULE, SPARK PLUG CAPS, COUNTLESS HOURS AND FRUSTRATION, what i feel it was, was this, i thinkthe 3 wires on ecu plug were making poor contact, causing them to get warm, inturn burnt the inside of pug out causing wires to arc out between themselves, thats why the liquid electrical tape fixed this, it was only a bandaid, so a new harness was in order, but the bending of the ecu pins making shure they were all making good contact, , i think was the root of problem,, good luck.... :yo:
Thank you! I read that post to and did check the pins on the old ecu at the time and bent them like he said to! I was testing some other components on it and found that the temp sensor for the ecu is not ohming out correct so it may be in s constant overly rich state all the time!
I have already taken it all apart and continuity tested every wire off camera, They all tested fine even bending them. I wrap the harness in better wire wrap and retaped everything. I had read the same thing about the broken wires on the harness!
Sorry to see your still pulling your hair lol it definitely looks like a ⚡️ issue I would definitely be ripping that motor and checking out that mag side
Also check throttle safety switch you can bypass it unhook it an I think you need to plug the other wires togather on wire harness side I don’t think you can just inplug it to bypass
I'd suggest working through some troubleshooting standard flow chart logic. Won't start. You have fuel = good, you have air = good, you have compression = good, you have intermittent spark = bad. Stick on that (ignition issue) then work down the tree testing each component in the system until there tested (with a DMM or service manual suggested test method) and verified then on to next component, repeat until have spark, then should move on to the other 3 items need require to make a 2 stroke run. Verify each component (and test equipment), all test good then loose wire, broken wire, loose plug etc somewhere. Troubleshooting has best success being applied methodical, you clearly had a spark issue right away and until get spark no need to know other items until resolve as not going to start without unless want to know if is worth sinking money into. Concentrate on 1 item, verify, move on to next. I can't tell you what is wrong in the state is right now or without doing the troubleshooting steps and everyone else will just be a hopefully educated guess. Intermittent issues are the hardest to diagnose but you seem super patient so enjoy the process. I'd plug everything back in and start from the beginning with electrical, rarely do multiple components die at once. From the video seems like the other components required to make a 2 stroke run are healthy enough to at least fire if not idle for a bit even if one 1 cylinder is totally toasted a cat suzuki 700 efi will start and idle poorly if have consistent spark.
If you watch the other videos you will see that I in fact did go through each component to verify. That is how I narrowed it down to a few components. But multiple components can die at once with a voltage and or amperage spike from a bad stator. The cylinders and pistons/rings are fine it has about 500 miles on a fresh topend and ran fine before it stopped running out on the trail, fi you watch the first video of this series you'll see what happened. This is a very common problem with these sleds and nobody seems to have found the root cause of it and many sleds end up getting parted out.
“The ole one hit wonder aye?” 😂 I’m confident you’ll get to the bottom of this. Good thing is you haven’t missed any real rides as there isn’t any damn snow out there.
Yeah! I went through and continuity tested all of the wires in the harness and re taped and put good wire wrap on the whole harness! But maybe there is a bad pin in a connector that is shorting it out!
I think it may be my temp sensor for the ECU, it ohms way higher than its supposed to and looks like its telling it to run in a super rich state. But just a guess!

TSS is eliminated by being disconnected. I used some starting fluid in it to try to get it to fire again and it didn't.
If it’s fuel injected, Fuel pressure is important too.
you have a short somewhere, shuts off spark, wire rub possibly
Was a faulty temp sensor for the ecu mounted on the bottom of then engine! Watch the next video!
Check wiring continety and for a ground short to frame
The fix was a bad temp sensor on the bottom of the engine, check out the latest video for it starting!
I would pull the magneto off and re check everything in there how is the keyway and key condition on the crank ? Maybe your key broke off
I'm going to get an OEM stator and see if that helps, this one ohms out but still may not be correct! I have pulled the motor and found the temp sensor for the ECU to be way out of spec so I am going to get a new one of those as well! Thanks for watching!

Open up the wiring harness and look at all the wires and check all the wires at every plug connector too. I have seen the wires break at the connector
I have already taken it all apart and continuity tested every wire off camera, They all tested fine even bending them. I wrap the harness in better wire wrap and retaped everything. I had read the same thing about the broken wires on the harness!
Is their by pass plug for handle bars for ingiton
Its all disconnected. It's a normally open circuit so it can be disconnected and still run.
Sorry to see your still pulling your hair lol it definitely looks like a ⚡️ issue I would definitely be ripping that motor and checking out that mag side
Maybe your magneto is grounded out on the flywheel
I can pull the mag side off again and see, maybe ill throw the old stator back on and see what does!
If sparks coming and going there’s definitely a break or a contact when there shouldn’t be
Theses cats will frame rub your wires too I’d be checking for that too
I'll Check, I have the brake like wire harness disconnected and the speedo pickup disconnected. I wonder if there is a short in my gauge cluster!
flywheel timing sensor?
Was a faulty temp sensor for the ecu mounted on the bottom of then engine! Watch the next video!
Also check throttle safety switch you can bypass it unhook it an I think you need to plug the other wires togather on wire harness side I don’t think you can just inplug it to bypass
It was unplugged when it started, but I'll try jumping it!

One side is partially seized on the exhaust side of the piston
The piston rings?
No, your motor seems healthy enough internally to at least start and idle compression wise.@@HeidisGarage
Yeah it should be, has a fairly fresh topend and ran perfect before this weird issue!
Try disconnecting the TSS(Throttle Safty Switch).
Its not the TSS, that was disconnected in this video. I have a video coming out soon that will show what the problem was.
Stator or cdi or you have a switch going bad
Has a new stator already.
Ohm the new stator and test pickup coil
I'll test them and post what the readings are!
“The ole one hit wonder aye?” 😂
I’m confident you’ll get to the bottom of this. Good thing is you haven’t missed any real rides as there isn’t any damn snow out there.
Yup it sure is!! Yeah your right nothing to ride it on yet! Maybe we'll eventually get snow this year!
Have you bypassed the kill switch and the thump switch?
Yeah, they were all disconnected when it started!
Bypass the Trottle switch that was the problem i had its usually the simple stuff we over loòk
It is bypassed already, all of the controls are bypassed
@@HeidisGarage take a ground wire engine to frame and to coil its sounds like a ground problem
It's not a fuel problem. Because ecu or ecm controls that.
Yeah, But it started with the new ecu and a different coil
Main wire harness?
Maybe! I'm wondering if its somehow frying the coil!
@@HeidisGarage Seems like theres a spiced wire somewhere grounding it out.
Yeah! I went through and continuity tested all of the wires in the harness and re taped and put good wire wrap on the whole harness! But maybe there is a bad pin in a connector that is shorting it out!
I continuity tested the whole harness and wrapped it in better wire wrap! I'm wondering if its in my hood harness now!
Does it have a tether?
It does not have a tether
I believe it's a switch problem
Or wiring
I think its frying the coil somehow
Ground, maybe
I did put a new ground on it when I checked the harness over! But maybe its still not getting a good contact! I'll clean the ground up!
Lol I own 25 selds mostly triples but I few twins I run 800 twin zrt 600 and 800 2 skidoo 800 triples polaris rxl650 and 800 storm
It's not a fuel problem I efi witch I don't own any its ground issue I'd run a ground wire from frame to motor to coil
I think it may be my temp sensor for the ECU, it ohms way higher than its supposed to and looks like its telling it to run in a super rich state. But just a guess!
Try bypassing the throttle switch
The throttle safety switch was unplugged when it started
