Seadoo Speedster wont start when hot!!

[Kennyamg]

I have a 2007 Speedster 150 with the 155 na motor. It starts right up when cold, idles great, no loss of power when hammering it. New plugs, new oil switch sensor.

After running it for a few hours and its off, It starts taking a few extra cranks before it starts. Thats when i know its coming... the next time i shut it off, i can crank it for days and it will not start. Get towed back to the ramp, load her up. Next day on the driveway, she starts up like nothing ever happened. No codes, no beeps, no lights. Anyone else have a clue or experienced something like this? Besides this, it runs perfectly, at a loss.

Could be a fuel pump trying to die on you. I had a car that would do that intermittently. Unfortunately, you’ll have to wait until it happens again to troubleshoot. I’d just go through the basics and check for spark and fuel pressure when it happens and go from there.
