Seadoo Xp 97 starts and after few seconds dies :( any body any clue??

Question

Seadoo XP 1997 starts and after few seconds dies. Ive changed MPEm control unit and still no change, what else can cause this problem ? Thank you

Answer 1

I would think possibly the fuel delivery...I might try this, after it's started hold a can of carb cleaner near the intake and when it begins to stall, hit it with a squirt and if it temporarily throttles back up, that would indicate a fuel delivery issue...you obviously have fire or it wouldn't start, so I would look at fuel delivery, good luck

Answer 2

Fuel.  Old Fuel.  Or not getting fuel to the carb.  I would check the fuel filter, the fuel lines, the check valve, the carb, the fuel pump.  Remove the fuel line from the carb and place in a coffee can, try starting the ski.  Does fuel come out of the line?  Also, try the carb cleaner trick.  If the ski runs with carb cleaner you know it is a fuel issue.  Start at the cheapest thing and work your way through.  If the fuel is old, siphon it out and do a fuel flush before you do anything else.
