951 le di p0230

[seadoonewb23]

I have a 03 seadoo sportster 951 le di. I am currently stuck in limp mode throwing a p0230 which is fuel primary circut malfunction. Also it will not idle it stalls out unless I am right above idle speed makes it a pain to dock or trailer. Replaced fuel pump with one from high flow and still have beep code (2 second beep minute intervals). Well I checked out my wires didn't see any corrosion, checked all fuses and none blown. Any ideas why else I am throwing this code. TIA

New fuel pump is priming and stays running above idle so I would think new one is good

This may sound strange... but check your voltage at the battery with a meter. Since it is starting... I'm wondering if it's passing AC, or going over voltage. If it does... the computer will do wacky stuff.

 

[seadoonewb23]

What is the procedure or just test volts right above idle or wot.

 

[seadoonewb23]

Battery 12.8 on 2k rpms and 4k rpms

Too low. Rectifier is bad. Needs to be over 13.5vdc.

 

[Dr Honda]

Yep... by 3K rpm or so... you should see a rise in voltage. It may not happen immediately if the batteyr is a little weak... but after a minute or two... it should push over 13v. Also... when regulators go bad, it can pass AC power, and cause all kinds of issues.

 

[seadoonewb23]

New battery always kept on charge when not in use I have rectifier ordered should be here tomorrow will give it a whirl.

 

[Dr Honda]

OK. Let us know what you come up with. Just an FYI... DO NOT start the boat hooked to a charger. If you get a voltage spike... you will kill the MPEM.

Still have beep code now VDC is 13.3 do I have to reset the code with scanner for it to go away

 

[seadoonewb23]

I saw this says resistance is suppose to be 6-8 ohms between 4-24 and 4-26 I assume engine off battery on. And I had 1.1 ohms

 

[seadoonewb23]

Started it back up and beep code is gone but wont stay running under 2k rpms

 

[Dr Honda]

When you check resistance... you don't need any power. but 1.1 ohm is very low.

OK... I'm thinking you have a couple problems. The fuel/error issue is gone... but now I'm thinking you have a broken reed in the cage. OR... your compression is low. OR... your air pressure is low. My gut feel is a reed.

 

[seadoonewb23]

Motor from sbt has 10 hrs on it. How to check air pressure. Also how to check if Reed is good or not?

 

[Dr Honda]

The engine may be new... but when you install an SBT, you reuse your intake parts. TO look at the reeds... pull the intake manifold and pull the cages.

 

[seadoonewb23]

Motor runs good at 2k rpms and up 55+ top speed.

What fuel pump did you buy?

 

[seadoonewb23]

One from high flow cany remember exact numbers was recommended on one of these forums

Ding Ding Ding! Get rid of that fuel pump and replace with OEM. Those fuel pumps are at best hit or miss.

 

[seadoonewb23]

Really. What's best way to clean. Also was wiggling wires going to tps and rpms started to go up
