I am not able to get my 2005 GTX 4-TEC SC started. I installed a new battery, the unit turns over, I am getting a spark. Any suggestions?

Spark?......
Well, if your getting spark and it won't start, you'll probably end up in the shop. Do you have any symptoms from the info center or anything to say that there is a problem? Did you run it out of fuel?
These things are such a nightmare with their "engine management" system controlling so much of the skis operation. There are like a minimum of 14 electronic sensors taking measurements and sending that infor to the mpem to be interpreted and sent to the ECU that controls the changes. If something is not working right, I would think it would throw you a code or something. But, when Seadoo made these engines, equipped to be plugged in to the VCK for the B.U.D.S. program to work with, they pretty much took repairs out of the "shadetree" mechanics hands. I hope to one day get the software to use on my laptop in order to work on these engines. Right now, 95% of my customers use the older 2 stroke engines. Mostly Yamahammers but some Seadoo's.........and of course, I own them both.
Sorry, I hope someone may have experience with them that I don't but I'm at a loss for you.

One solution that has sort of helped a number of this sort of problem is to spray some sort of propellant, (wd40 silicone spray etc) into the intake plenum. (don't use starting fluid!) and if it fires off, then you know several things. Spark is good, and timed right. And, if you can get it to run on the spray, for just a short time, it sometimes will allow it to begin running right, because it is running on it's own.
Another thing, I have a Polaris 800 4-wheeler. It had the SAME symptoms you mention. (The Polaris is EFI all the way) So, it turns out I had fouled spark plugs! Yes, for real, 4-stroke motor, fouled plugs. It took me 1/2 a day to change the spark plugs. They are way down in holes, and you have to remove alot of stuff to get to them. If you start, and run the Polaris 800 a number of times, without allowing it to heat up sufficiently, it can foul a plug.
So, from one shade tree mech to another, you might try that.
(did I mention I am opposed to spending money on mechanics!)
And, as always, use my advice at your own risk!:rofl::rofl::rofl:

I did not run out of gas and do not get any message on display other then the usual "maintenance". I think I will winterize it and wait until the warm weather. Thanks for the help.

What does the "intake plenum" look like and where is it located? Thanks

Intake plenum is what replaced the carburetor, with an EFI machine. It is on the intake side (as opposed to the exhaust) side of the motor. Air passes through here, on it's way in the motor. It has temp sensors, and usually has some sort of butterfly to control air intake rate.
Don't spray a whole ton of propellant in there, just a 1 or 2 second burst, while cranking. If it does not work in several tries, give it up. You don't want to crud up the plenum with alot of oil, but (I use silicone) I think silicone is a bit better.
Since you say you did not run out of gas, you likely have another problem, (like mr snipe above said) But, you can eliminate the spark and timing problem. If it will not fire, replace the plugs. Then it just may be fixed. If it does fire, then you know it is not the plugs. If it does not stay running, grab your checkbook, and take it to see momma, (down at the sea doo shop!)
(redneks do find a way to work on stuff!)
What I said may not work, but if it does, could save you a few hunnerd.

Does it have electric fuel pump?
When you turn on the "key" do you hear it pump up?
I somehow suspect fuel is the prblm.

I was in town the other day. Guy at gas station, trying to start his truck. Chevrolet. Had jumper cables all hooked up. I suggested that he turn on the key, crawl under his truck with a piece of metal (I handed him my 2" hitch and ball from the back of my van) and rap on the fuel tank. He looked at me like I was crazy, but for lack of any other answer, did it. Suddenly, he heard the fuel pump kick on, and I reached in and started his motor. He was ecstatic! I told him that this procedure would work for a while, but eventually he needed a fuel pump. Maybe something in that story could help.

Advice?.....
I agree with Nate, sorta. The reason I shy away from advise on these engines is because of the cost. If you do something without knowing the results, you can do major damage to a sensor or any of the high tech components without knowing it till it's too late.
I think you said this model was supercharged so I don't know if spraying any kind of petroleum product would reach the cylinder. Starting fluid use in a 4-TEC is o.k., since there is no oil needed for lubrication like the 2 strokes but I'd still only use it as a last resort and in small amounts.
If it's not throwing a code, (which if the fuel pump was out, it would throw a low fuel pressure code), then it may be something easy to find. It's just trying to trouble shoot from here or with the kind of info your giving. You've stated it didn't run out of fuel.....I guess the next thing I'd check is fuses and wiring.....:cheers:

Sniper is probably right... don't try that if if has the supercharger...
Hopefully a fouled plug is all it is...(Not real likely) But, cheap to fix, if that is it!
