MY 2001 GTX-DI died on the water under heavy acceleration - it won't start.
I was riding along - hitting lots of waves - and bam - dead.
It restarted one time, I went a little further - then died and no restart.

2nd time I took it out this season.

I checked the plugs - getting spark.
I checked the fuel pressure while cranking - between 100 and 110 - my guage isn't very accurate - but definitely getting gas.

Plugs are wet from fuel when I yank them after turning over the starter.
No blown fuses, it seems everything is plugged in and hoses connected, turns over fine.

I did notice it was a little difficult to start at the beginning of the day.

I was going to check timing, perhaps somethign broke (CPS?, TPS?) - but I am not so familiar with the process on a seadoo - I didn't find a factory timing mark to reference.


Any other ideas? Boat shop wants $200 just to diagnose.. Like - seriously??
 
So.. no ideas guys? Based on some searhing - perhaps it is something with the woodruff key and/or magneto??
I'm a little hesitant to dig in..
 
1) Did your gauges turn off when it died?
2) Look for a leak in the air system.
3) What is the pressure in the air system?
4) If the plugs are wet... did you put in a fresh set?
5) if the plugs are wet again... you may have injectors that are stuck open.


Just an FYI... there are only 3 or 4 guys here that can help with a Di/RFi engine... so you have to give us a little time to find the thread.
 
thnaks guys - I'll get back with the info.
When it died - I think the guages were fine - but I don't really recall ..
How would Igo about measuring the air pressure (Im assuming it's the other hose coming into the EFI unit).
I just bought a compression tester and a new set of plugs - hopefully tonite I can get some measurements.
Thanks for the responses guys - slow is OK by me - better than nothing :)
 
Yep... the air comes in the other side of the fuel rail.

Get us some numbers, and we'll get you running again.
