Hi everyone, hope everyone's enjoying this lovely weather?

Well as the title says I'm having fuel pump problems, now my baby broke down on me last night and I had to get a fellow is200 member ( lexusbingo ) to come out and tow me home lol, so this morning I run my diagnostics machine and found no faults?????? Strange anyways I then rung my brake down cover up and had them see if they could start it, he got it to start by spraying some carb spay into the carb and she fired up but as soon as he stopped so did she, so I've got a fuel problem with it getting to the carb so he thinks its the fuel pump, and I also think he right as I've been having problems with it for a while now.

So my question is do you think the same and if so how easy is it to change the fuel pump?

I've looked online and seen a few second hand ones for about £50 but don't yet no how much for a new one so if anyone knows the price for a new one?

Thanks for any help

Lewis

Fuel pump is easy to change I may have a working one at home. Surprised they didn't test it though for you. It's under the rear seat.

Also I assume he sprayed the throttle not the carb as the IS doesn't have a carb as it has electronic fuel injection.

Test the fuel pump first though mate. If you pop the rear bench out then there's a black plastic lid with three plastic bolts. Undo them and there's the top of the tank.

There should be a grey plug release that and there should be 5 connections in 2 rows. A 2 and a 3.

It's the row of 2 that are the pump connections. Put power across them (I can't remember which way round) and the pump should whirl. If it doesn't it's stuffed. If it does it may be something else.
