250 pro xs won't start

[krich77]

Fishing this morning motor ran great to first spot probably a 5 mile run an hour later went to move won't start. It real acts like an old carb motor thats flooded. I even tried to give it some gas to crank it it acts like it trying at first the the sound really flattens out. Guess I will be taking it to don when he says he can get to it. 250 pro xs 2b360010.

Kill switch? If not, check the fuses under the cowling. A bad coil can blow a fuse and keep the motor from starting.

I did check kill switch

Charge the cranking battery and see if it doesn’t light off.

[krich77]

I just got home checked fuses all good. I have charger plugged up now and will let you know.

[krich77]

Battery fully charged still won't crank. I'll call you Monday mr don

[krich77]

fuel pump running at key on ????? you got a fuel psi issue , possible split seal on high psi pump top

[krich77]

Pump is running for 5 seconds or so when turn the key on

[JOE54]

fuel psi test on stb rail at top

[krich77]

I am only getting 10 today psi of air on the port valve when turning over is that normal until it fires up?

[EuropeanAM]

No Kevin- using a glycerin-dampened gauge, it should climb to 90+ psi within about 3 revolutions of the flywheel (port side rail).

I will be in tomorrow and at least some of this week.

Just to update. Just picked up from Don and it was the diaphragm in the air pressure regulator. He also found an unrelated water leak and a service so I'm back in business.

You are lucky to live where you able to have Don service your motor!
