[HELP] GTX DI doesn't start anymore.If I remove a plug, it starts !

[iautran]

Hi (sorry if I make mistakes, but I am french )

I have a GTX DI (year 2000) that I am using for several years with no problem.

I didn't use it since last year (I have done everything as usual to keep it correctly for the next year).
Now, when I am trying to start up the jet for the first time this year, it is not working.

I plugged the key on the jet and I heard the "bip bip" correctly then I push the "red button" and I heard "tac, tac" and then "brrrrrr" near the battery of the jetski and then the counter is shutting down and I have to plug the key off and on to start testing again but with the same result.

I dont think the problem is coming from the battery as I have fully charged it, and I have also tested by connecting directly the battery of my car; with the same result (except that the "bip bip" is more powerfull when plugged to the battery of my car).

I have unplugged one of the two "plugs" (I hope this is the right term) and then the jet is starting; it is not a particularity of one of the plug, as if I reconnect the last disconnected plug and I unplugged the second one, the jet is starting !

Do you have any idea of what is wrong and how can I fix this issue ?

Thanks a lot for your help.

i would try a new battery as you might have full charge but you might not have full amps and batterys can go pretty easy

I agreee. Needs new battery.

Did you unplug a "spark plug", or what plug are you referring to?
Are you saying the ski starts on one cylinder?
Did you test the battery voltage with a meter?

About the battery, I have disconnected the battery of my jetski and I have plugged the battery of my car; and the problem remains.

For DooWacka, I have unplugged one of the spark plugs; the ski is starting on both cylinders and about the problem as said above I have tested with a "boosted" battery (sorry for my poor english )

It seems that it's a problem with the starter; do you agree with me ?

Do you know if I need to remove (pull out) the whole engine to change the starter ?

Thank you

when you are using your car battery, you are probably using jumper cables that are not making a good enough connection. that is why the problem is the same.

if you remove both spark plugs(put the boots on the grounding lugs), does it turn over quickly?

if yes, the problem is not your starter, it's your battery. I think it's time to buy a new battery.

FYI, no you don't have to remove the engine to remove the starter. nothing has to be removed, you just have to know what you are doing.

Hi,

thanks a lot for your answer.

I will test with a direct connection (without jumper) with my car battery and I will see if the problem remains.

You asked me to remove both spark plugs. If I do that, how is it possible for the jet to start up ? (I dont really understand, what you've asked me to do, sorry for my bad english )

Thanks

ski-d00 is telling you to remove both spark plugs so there is very little resistance to rotating (turning over) the motor. If the motor rotates easily, then the starter is working. It obviously won't start without plugs. The compression when the plugs are installed makes it require many more amps of current to "turn over" the motor. This will show up a weak battery that may appear fully charged with good voltage, but low cranking amps (power).

Thank you; I am going to test that this afternoon !

 

[iautran]

thanks a lot for your help; really appreciated !
I have followed your adviced and changed my battery just to be sure that it was not a problem with it and ... BINGO ! )

After charging the new battery, I have tested it and the jet started up correctly ! I didn't think of the battery because I was thinking that the test with the car was enough but you were true !

I have another question if ever you have any idea.
During all my tries to start up my jet, I have seen a lot of oil in my jet (more and more during my tries to start up the jet).
After that, I've cleaned the jet of the oil and I didn't try to startup my jet during two days.
When I came back, there were no oil leak in the jet; so I think that the oil is leaking during the start up process.

Do you think there there were "too much oil somewhere" because of my several tests that made the oil overflowed somewhere; or perhaps there is a joint used during the startup that is failing; or anything else ? =)

Oil leak in GTX DI?

It is possible your oil tank is leaking around the seam. The HDPE they used to make a large number of that generation of oil tanks is notorious for splitting and cracking around the seam that joins the two halves of the tank.

Check the oil line from the oil tank, through the filter, and to the oil pump for any leaks. You will have to remove the "glove box" so you can reach down and feel the length of the oil line for leaks. You can then also feel around the back of the oil tank along the seam. Remove the front storage container from under the hood to feel along the front and outside of the oil tank. You can also check the small oil return line from the starboard rear of the motor to the oil filler neck. However, most often it is the tank the leaks.

If your jet is leaking oil you need to change the fluid in it, along with the rubber o-ring gaskets (at least check that there is the proper amount). If you noticed oil one day and not the next your jet may be out of oil as they do not hold that much.

are you talking about the water jet nozzle at the rear of your ski if so thats where the exhaust exit is to and the oil is probably just excesive oil lying in you exhaust outlet from when you were keep cranking engine over and not starting it so the oil wasnt burnig off give you ski a good run in the water and see if its ok

 

[DooWacka]

It really depends on where you mean when you say oil leak in your "jet". You had been previously referring to your Seadoo as your "jet". If this oil is in the bilge of your Seadoo, then my previous post applies. If it is in the rear at your jetpump, then the other posts apply if it is leaking from the cone oil reservoir for the "turbine" or "jetpump". You shouldn't have much oil (just smoke) associated with the exhaust.
