i had the same issue two days back when i was on the road and the car just died, i didn't even noticed except when i placed my foot on the accelerator and felt that its not responsive. i took it to a car workshop and it turns out it was the "Fuel pressure sensor" however it wasn't just that, on top of the sensor it created an electric short that damaged the "ECU" luckily wasn't major and that also had to be fixed. i paid 200$ to fix it. i gotta mention your video made all the difference thanks a lot.

lmfao that's so funny I ordered one from longo Lexus last Wednesday 11/8/23 and it was like 195. They been lagging it and I had to call them today (monday) and threatened to cancel if they don't ship it and their excuse was "we been behind with online orders" but he said he will ship it out right now and then I got shipping info today after that call lol.

dont actually remember the details of symptom, but go through this thread for the answer, i do remember that this guy was dead on !! solved the problem, and made the diag easy, and also that the fix did not seem likely, sensor on back of engine below intake level, wasnt hard to get at, just swap it if in doubt.

[@PaulOneel]

I have a question. If you went as far as testing power and grounds why didn’t you just check 5v reference? Just trying to learn not acting like I know everything just questioning. Seems like it was guess work/ experience that found that and not necessarily diag. Don’t mean that rude but over internet is difficult to explain. Lol

[@OzMechanics]

I always start by verifying we have good powers and grounds then we verify our 5 volts. Start from the roots and branch outwards. And it’s all good brother thanks for stopping by and watching

No start, no crank, no communication with the Engine Control Module (ECM) and the check engine light doesn't come on when the vehicle is in accessory (Key on/ push in). Need to replace 23280-31020, Fuel Pressure Regulator. this problem also applied to Lexus IS350. Basically, fuel pressure sensor shorted killing 5v ref. Sensor connector is behind left rear of intake. To verify you can disconnect the fuel pressure regulator, engine now from no crank will crank (but of course no start) Reply if you fixed this no start.

You mean fuel pressure sensor not regulator right. I'm having same issue with my 2013 GS350 waiting on part to come in.

[@dtnel]

IS this relevant to the 2010 RX350 vehicles as they went to jump start it, car had been on used car lot from Auction for about a month then they went to jump start as mentioned above. Replaced 4-5 fuses in underhood fuse box and have to go back to check fuse panel under the dash as still have no comm on the dongle scan tool but able to pull codes using a wired scan tool but alot of active & also history codes for "lost comm" or "no comm" on alot of modules. I've identified one potential fuse under dash I need to check. Also there's a aftermarket valet switch for a aftermarket remote start system that's installed but they said the car fired every time prior to this. I'm thinking with so many blown fuses that they potentially hooked up jump box cables backwards or it has the issue in this video. LMK your thoughts in regards to if this vehicle has this known issue with the fuel pressure issue that could be causing no crank no start and the no comm issues.

[@Q60MATTYICE]

If I replaced the sensor and it still doesn’t turn on what is the problem I got p0087code

[@spelunkerd]

When the sensor knocks out the parent device, something is wrong with the engineering design. One would think that the design would insulate the computer from overvoltage in the line, individually shutting down the sensor circuit before crashing the computer. In this case I don't know how you knew the lost 5V reference was a cause rather than a consequence of the problem. I keep seeing disconcerting examples of that. Checking power and ground isn't enough before condemning a module or computer....

[@OzMechanics]

Yea, Ford does the same thing on some of their vehicles. If done a handful of jobs were 5v ref kills communication with the pcm. Crazy
