You are certainly entitled to your opinion. I stated "likely". My 40+ years of electronic component servicing has commonly seen electronic equipment remain in reliable service for far greater spans...

He indicated he was from Australia. We have a few members there who have Digital Wrench (DW), the diagnostic software. With that and a cell phone QR code reader, you can determine if the injectors...

I've been working on my 2020/2021 winter project PWC, a 2003 Virage i. Upon removing the fuel canister and visually inspecting the fuel pressure regulator (FPR), I thought I had received a "free...

Blasphemer!

It is time to perform the compression test queried in post #2.

I'll save you a bit of working in the "blind". The 40 Pin connector retaining screw requires a 4mm hex (Allen) wrench.

I was surprised when they left the watercraft business. They had been in it for quite awhile and had a strong following. More significantly, they had just designed release a new hull in 2003, the...

Reinforcing the fuel pressure regulator is fairly easy on a Genesis, as compared to other models. The failure is not relative to hours. Bouncing down the road on the trailer will shake it out. In...

Also, you need to keep the magnet polarity in mind--north/south and not reverse any of them.

FYI

Just because a path measures with 0 ohms of resistance is no indication of whether the connections are secure and it can support a high current load, such as a starter motor. For example, a...

Does it settle at zero and remain there, or does it flutter back to 15 - 30? It should settle quickly to zero and remain there. If it doesn't, I suggest you find another meter and re-run the tests.

Ditto bfarnam. Also, a change in the exhaust system will impact the flow, which will, in turn, impact the fuel/air ratio required. As the fuel injection system is an open loop type, it will not...

Well, as I indicated in our email exchange, I did not fair any better. The canister return line barb snapped off when I was razor cutting the hose off.

I believe I've come up with alternative...

Disconnect the hose and remove the hose barb/orifice. Clean the screen with a fine wire brush gently. They'll be a decimal number stamped on it, which is the diameter of the internal orifice. I'll...

I would highly recommend you replace the nylon head piece. A fuel leak in a PWC can quickly turn into a tragedy. The leaking gasoline will quickly vaporize in the hull, due the high temperatures...

That's it.

You don't need the starter drive to check the fuel pump current draw, if you want to keep moving on this.

I'm a little too far to help.

The red/white wire come directly from the battery, via a circuit breaker. So it is hot all the time and does not turn off with the engine. The brown wire is the ground path from the fuel pump. The...

As I've commented before on your queries regarding engine/fuel/exhaust modifications, the EMM is an open loop fuel injection system and will not compensate the air/fuel mixture for the modifications....

Both of mine are in the lift, in the lake. Next time we go out, I'll try to remember to make the measurement.

I did, also, find this in the service manual:
...

If it is backfiring, it is 99.9999999999999999999% likely the EMM is malfunctioning.

Yes. The fuel pump ground path is through the EMM. It does not enable that ground path until it sees crankshaft rotation from the CPS. Of course, it has to be powered up to do anything and it is...

What is the optimum operating rpm range for this ski?
The EMM will limit the RPMs. In nearly all I've encountered, it will limit RPMs before the throttle flapper runs out of opening. I really...

Another member had an issue with his MSX140 with very similar symptoms. Ultimately, the issue was an aftermarket stator with an incorrect pin out of the connector plug.

Here is the thread...

Leave it to Captain Pete to come up with a better method to skin an onion.
