I have a 2004 MY05 Jap built AWD RX330 that won't start. It is almost 12 yrs old & has 115k miles on it. This is the very 1st problem I've had with it.

Some quick checks indicate that it may be power supply to fuel pump or fuel pump itself. No sounds from it when turning ignition on.

Does anyone have a wiring diagram for the 5 pin plug for the fuel pump? I'd like to put a meter on it or connect 12V to the pump directly before I remove it.

Thanks in advance.

Yup. Got it. Many thanks ericg.

Power supply OK. Pump dead.

Any tips on how to remove?

Thanks again.

I saw that thread on the AU site as well. I have already removed rear seat to access pump wiring during my checks.

I'm a little worried about breaking the large white plastic cap while removing.

This is for an RX300 but I believe that the white cap is the same
