RXDI No Power

[330xi]

Good afternoon,
Last year my rxdi developed an issue of where I didn't have enough power to plane and it would only go to 6200 rpm if I did manage to get it to plane. Also would idle low and die if I let it idle too long.

I've done a compression test, 138psi exactly on both cylinders, replaced both fuel filters (inline filter is not a brp filter, got a filter that is capable of 120 psi constant from a local auto store), and I've also tried fresh 91 non-eth. Ski has 180hrs on it.

Where should I go next? Thank you.

I would like to add that I do not have a service light on.

What is your fuel pressure? If low, it will not run. Also check your wear ring...

Haven't checked fuel pressure yet.

I know it wouldn't be the wear ring as the ski simply won't rev. Trying to plane out it goes to 4200 and stays there.

Good point. You can build a fuel pressure guage fairly cheep. The fitting can be bought from advance auto, and a gauge can be a harbor freight compression gauge

Will do! I'll test that Tuesday when I get home from the lake.

Update: got a fuel pressure gauge set up, and at idle the needle bounces between 80 and 95, while on plane or wide open its a steady 105-110psi.

Checked the reeds yet?
Might also check the voltage across the battery terminals.

Battery is right at 12.2v. Haven't gotten to the reeds yet

Also, just pulled the raves for cleaning and one of the o rings was torn.
