Greetings,
So I got a call from lexus that my car isnt starting because of my Fuel Pressure Sensor and would cost $2700 for repair and the sensor is only sold with the rail and changing the rail might damage my injectors and need replacing. I was able to get just the Lexus OEM sensor, new. I have looked up a bit of info on installing it and looks pretty easy. I know to let me car sit and cool down to decrease amount of fuel pressure, which is fine since my car hasnt started in three weeks. I also know how much to torque the sensor.
But what other things should I know before doing this? I do need to remove the intake manifold to get to it right?

Search the boards and read some posts. There are a lot of people who have done this.

The sensor used to be listed separately, but Lexus has updated the parts catalog and now only show it as coming with the rail. This is most likely due to the issues that caused the recall to replace the gasket and make sure it wasn't leaking. That said, I believe the part should still be available separately. 89458-30011 is the sensor 90430-12026 is the gasket. It can be difficult to replace it with the rail on the car, though it can be done (see the recall instructions for more details of how Lexus recommends doing this/cleaning the surfaces).

Make sure to remember to relieve any additional fuel pressure by removing the fuel cap. Only minor, but will help. Make sure to have any specialty tools on-hand when working on the factory fuel lines/rails. Not sure if this is the case with our 2IS Lexus, but some makes require special tools.

Good luck on the repair!

My car has this recall available now along with the airbag. I just not wanting to take it and getting it repaired. Wouldn't want them to call me later that my car won't start. I don't want to shell that kind of cash if they try to say it was broken now. The car is running well to have it damaged over a gasket change.

If I had to get the recall done, I would take a picture of the sensor and wiring before bringing it in, I would mention to the service advisor that I have heard of various people having issues with the sensor after the recall and that I am aware of the damage that can occur if care is not taken when unthreading the sensor as far as the wiring goes. I would also tell them that the car is running fine and that there are currently no issues with the sensor and that I hope that continues after they do the work they're supposed to be doing, because it's going to cost them quite a bit to replace the sensor if it starts having troubles after they do the recall.

I would then take a look at the sensor wiring after the job is done (it's not easy to see) and make sure things are on the level. They've done a lot of these recalls now and are probably pretty good at them, so I doubt you will have any issues, but you never know.

Just saying, I want them aware of the fact that I know it's a tricky procedure and that if I have a problem a few weeks or a month from now, I'm bringing the car back, and I don't think it's going to be on my dime.

I have very little car knowledge but I was able to replace my FPS in about an hour and a half. Spent a good amount of time trying to remove one particular hose but other than that was very easy. $2700 repair that only cost me under $50 to do myself.

That's a huge saving!

Beware!!!
I had the recall done on my 2007 IS 250 in November. Lexus replaced the gasket on the fuel sensor when they did the air bag recall. 6 weeks later my car won't start. My car is in a local shop waiting for a new fuel sensor.
$1,200.00 repair. $100.00 tow bill.

This stinks.

If all you need is the sensor, the part number for the sensor only without the rail is 89458-30011, the gasket is 90430-12026.

The newer parts catalogs no longer list them separately, however they should still be available at this time.

Looks like I'll buy the gasket now and save it for if it ever leaks. Hopefully not until my next plug change. Are the fuel sensos prone to failing?

No, the sensors are typically not an issue. The concern is that when removing the wire, care must be taken not to twist the wires. The only times I've ever personally seen an issue with the sensor is after the recall to replace the gasket, most likely because the tech doing it wasn't careful with the wire.

Hey Jeff - do you know what the difference is between the sensor with part number

Just guessing but when you see minor rolls in the PN like that and the later has an improved gasket, one would think it could simply denote, the improved gasket material but it could be anything on the assembly that helps its reliability. Like a wire strain relief if wires are known to get damaged.
