Great video, I like your troubleshooting. I’m glad you figured it out. It seems like with all of these aftermarket replacement parts and even some of the oem parts a bunch of these skis would’ve been fixed on the first try but the parts are not very good and you end up chasing your tail until you get a good replacement part.
All of the Quantum Fuel pumps have lifetime warranties. I had the new model shown here in my DI and the silver extension broke or rather failed at the base. Quantum sent me a new one with just a little RMA work.
@@SeadooRefurb I would like to add. Thank- your for showing these pumps have a check valve which should be verified before installing. I knew one existed but thought in the fuel body and not in the pump.
@@SeadooRefurb I needed to replace both of my fuel pumps for my GTX DI (2001 and 2002). The 2001 was in a garage for 20 years and fuel turned to turpentine. The 2002 was used well and thus just wore out. I fixed a friends DI which how I got on the band wagon fuel pump as well. It is the first thing I check when not starting or performing badly.
Great videos you make! I have a question regarding my 01 GTX Di and I’m new to jet skis. When starting it cranks over no problem, but to get it to run I have to squirt a shot of carb cleaner in the throttle body. Then it will run all day, but let it sit for 24 hours and it’s back to not wanting to run again unless it sniffs some carb cleaner. I replaced the fuel pump, fuel filter, and fuel regulator all with Quantum parts. Removed the fuel and air injectors and cleaned them the best I could and replaced the spark plugs, great spark, but it still doesn’t want to run unless I give a little spray of carb cleaner, which I hate doing. I’m waiting on my tool to arrive so I can check fuel pressure at the rail, which is taking some time to get to me, but I’m running out of ideas on what it could be? Could it be the fuel pressure? Hoping you could give an idea to look into, thank you.
It would seem that you are loosing air or fuel pressure. The Jet boat we were working on did the same thing. I did not use carb cleaner but had to crank it a long while to get it to start. My best guess was that the fuel pump had a bad check valve in it. ( I had a quantum pump do the same thing) You need to hook up some air and fuel gauges to see what is happeing.
Great video, Question, had fuel spill over in fuel rail to air side which cause fuel wash in compressor and then failure of compressor. I am replacing all of the o-rings in the fuel injector, air injectors, and regulators. Any other suggestions?
hi I congratulate you because you seem very strong in your field. I am contacting you because I have the same gtx di from 2004 and out of the water with the hose connected it works well and goes up to the maximum revs but as soon as I put it in water it does not exceed 4000 rpm could you help me?? I see your video from France, thank you
@@SeadooRefurb thank you for your response, it's very kind. The jet worked very well before, but once I started the jet ski with the water hose on and I went to buy gas and when I came back my father I had turned off the jet ski but not the water and since then it has been like that. I put a new injection ramp because I thought it was coming from my but no.
I have a 2003 sea doo gtx di and once I connect the dess key I do not hear the buzz noise. I assume that noise is the fuel pump??? I do hear a click in the rear electrical box. It will turn over, but will not start. Again assuming this is due to the fuel pump not making noise (pumping fuel). Fuses all look good. good spark and good compression. Fuel pump has been replaced. Where do I go from here?
Ugg, Electrical issues. Remove the connector to the fuel pump (connector on top) and see if there is any power going to the pump. My guess is there is a bad fuse somewhere.
So I’m looking at a 97 seadoo gti the shaft that goes to the impeller is stripped am also needs a carbon seal do u think the pto is stripped and will need a motor pull an a new pto installed ? I need help deciding lmao
pto is easier to change with the engine in the machine. you will have to remove s spark plug and put some rope in the cylinder to stop the engine from rotating. then install a pto removal bit and a breaker bar and you should be able to remove it.
Pikasooooo I like ettt 🤌🏽 I been saving your videos because I got a 951 rxdi in a trade and I have no knowledge of anything seadoo! Watching your videos you make everything look to easy to work on 🤘🏽
Question sir my 2002 gtx di won't rev over 4750 rpm, It has 130 psi compression on both sides, 107 fuel pressure while running at high rpm, good air pressure, new fuel and air pressure regulators, a new fuel filter, reeds are good too, the throttle is working, the rectifier is good to my knowledge, wear ring and prop almost new, not flashing maint or any other codes. Do you have an idea of what's going on? I bought it not starting and got it running and I have this problem now and it's driving me crazy.
Just my two cents, That sounds like your RAVE valves are not opening Or long shot is your Water Valve on muffler is not closing. I would check the RAVE valve solenoid and make sure it is opening when commanded. At the same time, pull your RAVE valves and make sure they are clean and check the sealing ring. As a side check, un-connect the line from solenoid and blow 80 psi air into the tubes. You should hear them click open. I like to remove the cap while injecting air and spray soapy water. If you have a leak from the Sealing ring, You will see bubbles. Later. Hope this leads you into the correct direction.
Also thinking here, start your ski with the seats on, turn off and remove seats, If you smell even the slightest smell of EXHAUST. You could have an exhaust leak between the head pipe and the exhaust cone. This will reduce backpressure and cause loss of power depending on extent of leak.
@@grast5150 thank you for the help. I have one rave valve (PTO side) that leaks slightly but I open and close them with an air compressor while reving the engine and it makes no difference. Do you have any thoughts on that? the solenoid is working because it opens and closes them when shutting off the engine but I did confirm with a bore scope they are not opening when revving, I've tried adjusting the caps but no difference. BTW this issue is in water and on the trailer.
@addielb8086 I think your issue is RAVE related. I would replace both sealing rings, clean and try again. Once there is backpressure from ski in water. You need the RAVE to open or engine is limited due to back pressure. Could you also check spark on PTO cylinder? also check spark plug, is the PTO wet. Maybe you are running only on one cylinder? Don't think this but maybe spark is weak.
Exactly the right topic for today.

yep. I See a lot of bad parts. makes trouble shooting a nightmare.
@@SeadooRefurb I have the same issues on the turbines I troubleshoot

@@grast5150 Amazing how many people are having issues with the fuel pumps. I guess 20 years is the limit on the factory ones !

High resistance at 4 wire plug,drops 4 volts while testing

(1) You are using a learner key (2) Broken reed valve (3) Bad fuel pump if it is very "jerky" when trying to get to max power.
