New kid on the block… “water”

[ProStreet1]

Hey all:
I know a lot about gas automobile engines, a fair amount about boats and “0” knowledge about waverunners. I bought one last night, supposed to have ran fine when parked last year. Goal is to charge the battery and get it started 1st. It’s a 2001 Polaris Genesis 1200.

I honestly am not sure but I believe may be carbs vs fuel injection.

I did read water connects to the rear(somewhere) start engine and then turn water on and then water off before turning engine off.

If it does start and run as advertised, can someone explain how to change the fuse in the display unit.

Thanks for any help…

My apologies… this is a 2001 Polaris VIRAGE TX. The display is not working but I am able to get it started but it won’t run under 1/2 throttle or better and no where near an idle. Can this be a characteristic of needling a CDI box? My thoughts it definitely is a fuel delivery issue. All cylinders are hitting and I assume the CDI box controls the 3 injectors. I have no issue with buying a new box if it’s needed

Now I feel like we are getting some traction... I have ordered the fuel gauge set-up to check pressure at the shrader valve to confirm yes we are good or not. Sounds like we want 20psi with pump running and with return line pinched shut somewhere around 30psi. I think this is a good start and I'll report back when I have some clarity with this.
Certainly appreciate!!

Even if fuel pressure is good, you will need to verify that the regulator mounting has been reinforced. When pulling the pump module on one of my MSX140s, the regulator fell out. They cannot be trusted to be held securely in place with the factory design.

Probably a stupid question but I should be able to get over and check fuel pressure soon. If I have 20psi or better when the pump is activated, and then 30psi with return line pinched off, we assume all is good?
Then If I need to get to the pump and regulator, this is all attached to the sending unit within the tank?

Thanks

Why when I attach a fuel pressure gauge to verify pressure it reads 0. I then remove both lines and turn the pump on and the line without the shrader valve pumps fuel. Is this common the shrader valve is on the return line?… makes no sense at this point

Yes, the pressure is checked and pressure regulator is at the return line, that way the entire system has steady pressure, including the injecters.

Pinch the return line after the test port, see if pressure goes up.
It is posssible to have fuel flow but no measureable pressure.

I just did this today. The fuel pressure gauge does not depress the Schrader valve. My gauge came with an in-line T that I put in and it worked fine.
