1997 sea doo xp runs for 10 sec and dies will start again and die

[wilsonseadoo]

i am having trouble when i start the ski it will run for about ten seconds and then it shuts off like you cut the spark plug wires. you dont even have to take the key out and you can start if back up right away and it will run for a short time and do the same thing again. it has a good battery and i have looked over all the electrical connections and all the pins and wires seemto be fine. i have tested the oil sensor and its fine. i am not sure how to test the key switch to see if it is good but if any one knows how to or have had this problem i would like to solve it i am a four hours from a sea doo dealer and having trouble getting anyone to work on it.

Is it a fuel problem...it could be dirty carbs.When is the last time you pulled them apart and cleaned them? Also are the spark fresh and gaped properly?

[wilsonseadoo]

no its not a fuel problem i know its getting good fuel and i took the carbs apart when i got it and cleaned them all up since it had been siting for four years not running. i am pretty sure its am electrical problem but i cant find any thing wrong.

This is one way to be sure that it is not fuel related. I am sure that there is even a beter way it just does not not come to mind. With the ski outside and a fire extinguisher very close. Mix a spray botle with gas and oil and start the Seadoo and as the engine starts to die spray fuel into carbs if it does [not] try to stay running I would say that you are correct and it is [not] a fuel problem. :cheers:

I remember doing that as a kid with my snow machines. Great point about having the "fire extinguisher", might want ear plugs too i've seen some huge back fire explosions doing that. :rofl:

 

[wilsonseadoo]

ok i will give that a shot tonight and write ya back and let ya know for sure if it is not that would you know any way of testing the teather key on it like where i would have power and where i would not have power. i was thinkiing it had to be the key switch or the comuter in the front of the ski but i dont know how to test them.

 

[kustomkarl]

Uh...don't try spraying fuel into the carb throats. That's not a safe thing to do, and it could cause a fire! As a Kid we all did foolish things because we didn't know any better. Check the plugs and see if they are wet from fuel. Are you getting the 2 beeps with the DESS cap in place? I would first clean the cap and DESS lanyard with soap and water to see if it might be loosing a communication to the MPEM,( Multi Purpose Electronic Module). If it looses It's connection it will stop runing like you pulled the lanyard off.

Hey, I just seen you were from Haxton. Little cold to ride isnt it ? Where do you ride at Enders ? I lived in Champion / Imperial years and years ago...

 

[wilsonseadoo]

ya we go over to enders quite a bit and jumbo and big mac but mostly jumbo.

i have looked at the dess and it seems to be clean. is there any way to bypass the teather dess and use a jumper wire or something. i am going to pull the carbs off tonight and see if i lost a diaphram again too.

I dont think you can bypass / jumper anything.. As far as the carbs go look real close at the tiny filters that are in there. This is an older ski with the grey fule lines.. You will get a clear build up of gunk in the filter that resticts the flow of fuel..

 

[wilsonseadoo]

ok if it is what kind of hose do i put on to replace the gray lines

 

[kustomkarl]

You can't by pass the MPEM. Go to a auto store and buy fuel line to replace. If it has gray fuel lines still they deteriorate from the inside out and will clog even newly cleaned carbs.

This is from someone who has said it best. This is the best idea that I have heard yet. but the only problem that I see with useing the pumps is that if they are starved for fuel then they will not be working if it were to be runing out of fuel.[Starving] You do have a chance of fire if you use the gas like I have mentioned. I have seen fire maybe 3 or 4 times in 30 years it is allways small. this is out of a thousand tries. Good luck and be safe. :cheers:

On a 97xp they have accel pumps on the carbs that spray fuel into the carb when you pull the throttle, you don't need to squirt fuel in the throat of the carb. If it doesn't run when you feather the throttle it is fuel related. When you cleaned up your carbs you should have replaced the grey lines along with cleaning the fuel petcock. Also did you clean the fuel filter that is under the hood? if you did then make sure to get the bowl secure on the threads or it will suck air and your ski will not run.


BTW you can by-pass an mpem with the use of a msd enhancer..,

 

[wilsonseadoo]

i am going to try looking into the carb tonight and see what it looks like i hope i do find plugged filters in there or something like that while i have it off i am going to replace all the fuel lines and make sure they dont cause me any more problems if the havnt already.

 

[robin savell lloyd]

Good luck I hope that we are leading you in the right direction.

wilson, is this happing on the trailer or riding the ski?
1997 seadoos were famous for bad dess post's
me thinks they had a bad batch back in the day
if the ski does this on the trailer, i doubt its the carbs
prolly the post
but let us know were it happens

[wilsonseadoo]

i was wondering about that it ran fine almost all summer but then on memorial day weekend in neb it started this all in one day and no leads on it just happened and then it would not quit doing it. it does it in the water and on the trailer. and ideas.

 

[wilsonseadoo]

i was working on the ski tonight and i tried spraying carb spray in the intake when it started dying and i still died. the carb spray will not keep it running. so i have found out that it is not a fuel problem since it wont keep running on that. i am still wondering if it is the dess peg and teather key. i am not sure what all the wires are supposed to do or when they should have 12 volts or it they even need all that or if they need like 3 volts in certain wires. if anybody has any ideas i am more than open for ideas.

Any "dess" post will work, new or old, as long as its in good condition. Maybe a friend will let you borrow his. Takes few minutes to change out, however you can not bypass it, because the dess post "reads" the ROM chip inside your landyard key.

 

[robin savell lloyd]

Carb spray? Is this staring fluid or a carb cleaner spray? as I have seen many carb cleaners with a high flash point. Even though they seem very flammable they may not work as a starting fluid would. What was the flash point of that spray? Starting fluids are very bad for engines as they can break pistons, rings and things and they are a safty issue also. :cheers:
