1997 sea doo gtx won't start

[Kelleyhead]

Just had carbs rebuilt with new points and it ran great just had to replace/build a new exhaust hose and now it will not start. Computer gives me two beeps on diagnostic test, engine turns with spark and compression, fuses are fine and i have checked the ground wire to battery from MPEM and even run a new one to be safe. Light test shows ground good to it even thru plug. it was running before I put on exhaust, and even with exhaust off now just wont finish. Every plug is tight, only thing I had left to do was adjust idle screw but cannot get it to start. i am a mechanical guy from autcross and never been that good with electrical. Now I have checked the posts and have no corrison, help I am lost and I it is killing me not to be able to find what got hit or cut. One thing I did notice is my temp sensor is broken but that should not stop it from starting right? HELP my triplets are killing me to get it running. THANKS

Hi and welcome to the SeaDoo forum.

If you have spark and compression the only thing left is fuel. Check all of your hose connections for leaks also check to make sure you don't have any fuel lines crossed. Check and see if you are drawing fuel from the tank.

Try putting a little premix directly down each cylinder. See if it will start.

it ran after the rebuild great just had a rigged pipe on it to twater test. My new pipe need rings to keep it on but it ran. Then came back to lake the next weekend with rings and I think I hit something because it is just turning and turning but never firing off. I ddi mess around looking for idle screw since my mechanic didn't set the idle, and I trickle charged the the battery for a while, yes still hooked up. Anhy ideas as i have been running thru the service manual but I am lost since it seems like I hit are maybe since it ran fine before

 

[Kelleyhead]

by the way i emptied fuel filter 3 time and it kept filling up and I had all the grey fuel lines replaced, also smell fuel when I pull plugs and ground wires on the elec box.??? totally stumped and yes tried spray and adding mix to plug holes, guess what nothing. ugh

Question for ya, have you checked it for spark I mean taken a plug out grounded it cranked the motor and seen spark?

Oh yeah first thing I did before adding s

 

[Kelleyhead]

Oh yeah first thing I did before adding spray and then gas and then I tried runnin a new ground from inside the electrical box to battery. I think maybe I might have blindly turned the MAG low spelled screw thinking it was idle screw since I was just going by touch. Not sure if that would screw up the works and prevent it firing but going to re adjust both back to where I first get resistance and then move them back into place. Any other ideas?

you said it ran during your "water test" but then it wouldn't start at the lake. are you saying it ran on the hose, but then you put it in the lake and it wouldn't start or did it die while running in the lake?

I'm wondering if you had the hose running with the engine off and got some water in the cylinders causing it to not start.

 

[LouDoo]

About all that's left is timing. Are you sure the rotary valve is in time, might have stripped the gear. We might need a Doctor for this one.

We had a problem similar to this one a couple of weeks ago, I'll see if I can find it.

It ran on the hose under my porch just needed a new brace to keep hose on water box but when I came back to my lake house with it it wouldn't start but I messed around looking for idle screw which is why i thought maybe it was a low speed screw issue or wiring. Has not been in water since and I saw no sign of water in engine just gas/oil came out when I pulled plugs. Kinda freakish to me

 

[Kelleyhead]

If some water did get in what is the best way to get it out?

 

[brock1]

when you crank it over with the plugs out if no water is coming out then your ok..... as for the gas and oil shooting out thats normal if you have been trying to start it it will build up in there if its not firing.....

 

[bigJake]

crank it with the plugs out to get anything built up in there out. if water comes out, spray in a little fogging spray. then put in fresh plugs and try to start.

well once again we proved that great minds think alike AND that you type faster than I do :thumbsup:

 

[Kelleyhead]

ok ok guys,I reset the lowspeed idles and advanced them 1/8 but still no start/fire just endless turn over. I tried to do the possible water issue cfrank again but still no water just mix and i am still thinking elec issue so I am lost

 

[JJinSC]

Have you tried to crank it as if it was flooded? Try this. No choke, hold full throttle and crank in 10 second intervals for a few tries and see if it will fire. If it does, hold full throttle till it clears out. If you can get it cranked this way, you have a flooding problem.

 

[Kelleyhead]

Tried that and even tried the trick after a cab rebuild of full throttle and choke fully engaged. So if it's flooding what should I do? If I can't fix it tonight the wife is going to make me take it and that might mean no Doo till next year

 

[Kelleyhead]

Anybody know of a way to try and bypass the coil so i can see if it's bad. I have an old analog ohmmeter but not sure what I need to do to check it. Thinking maybe I could have cooked it trying to charge the battery while hooked it or cooked something

 

[brock1]

if you have spark then your coil is not bad. But .... fi yuo would like to check it just for clarification you can take the hot wire that plugs into it / take it off and make a 1 foot jumper wire and snip both ends back and shove one end ito the wire and take the other and touch it to the engine block and crank the engine over and see if it arcs. If it arcs then the coil is bad. But remember this is useless if you know you have spark at the spark plugs?? Make sure you leave the ground wire (black) on the coil while you do this

 

[Kelleyhead]

Cool thought so then whats the fastest way to check and make sure i am getting fuel because my fuel filter fills back up everytime i dump it out

 

[brock1]

unhook the fuel line going into the carb and stick it in a glas and crank the engine over and you should see fuel going into the glass if not either your lines ae blocked or you have a problem with the pulse line

Brock your inbox is full

 

[Kelleyhead]

Unhooked return line and cranked it for 5 sec or so and gas came out so is that good or is that a sign of closed needle valve?

 

[brock1]

so then fuel is not your issue here so rule that out. What are your compression numbers i seen you said you had compression but what is it? the only other things it could be are air or spark IF???? the compression is good. as for the spark test did you do it???
