Fault Code PO232 Walbro Pump
Just fitted a Walbro pump and I am getting a fault code PO232 and the engine check light coming on, fault code comes up as 13v power short or open circuit wiring. Ski has cut out a couple of times but restarts ok first time.
Checked all wiring and it looks ok, as you know pump is on a multi plug etc.
Anybody any ideas or have you seen this before

Go to the parts store and get you a 12 VDC relay, run the pump off the relay with a fused link at the battery. Use the original fuel pump circuit to control the relay. Problem solved!

Cheers for the info, I may just take the pump out and put the OEM back in as the ski is only running a mini rude now.
I have had Walbro in another ski and never had this problem or a fault code
The pump is a genuine unit.

Did you replace the fuse with a higher fuse when you installed the walbro? I replaced my 10 amp with a 15 amp because the pump draws more than 10 under load

Just piggy back the power wire coming off the relay into the fuel pump harness, mine works just fine on a new px with a walbro

i always thought these weren't a direct plug and play installation..

It was plug and play in my 08 x.

Been out today and blown around 1/2 tank off and no fault code has come up at all? Going to give it another try next week to see what happens, but fitting a relay is going to go on the to do list.

I've only seen the code when testing 95#+ pressure... if you've got to run that high of fuel pressure, it's time to use larger injectors anyway, and then problem solved.
