No Crank, Check VSC, cooling fan runs.
So my 07 gs350 120k miles decided she didn't want to start this morning.
She fired up for a half a second, then died.
Pushing the start button everything else works but she won't crank. Dash says Check VSC and cooling fan runs right away (cold engine) and keeps running (very strange). Charged battery (OFTEN THIS MEANS THE BATTERY IS WEAK< SO JUMP START BTW) , disconnect/reconnect battery 5 minutes. Did not work. Battery charged and good. Jiggled auto shifter in and out of park to make sure it was in park. Didnt work.
Researched and found another poor soul. Ended up being the Fuel Pressure Sensor under the throttle body above bellhousing , back of motor. You can check either cam timing sensor (3 wire, single bolt on top near front of valve cover, blue wire for 5V reference. If no 5V then the pressure sensor is shorted, replace.

There is a recall for a fuel leak at the pressure sensor, they will not replace it free, they only change the gasket and/or tighten.
Just wanted to let everyone know in case they come across this.

I've got a 2013 GS350 and I checked with the 5V reference from the cam timing sensor and get 5V but after about 10-15 seconds pass while in the ignition ON position the engine fan runs and the voltage drops to 0V. Also cannot read anything through OBDII port either through a regular reader or through Techstream unless I try to be really fast and can get something read within a few seconds of reading from the regular OBDII reader. Would you say this is indicative of a bad fuel pressure sensor and I should replace it?

Hey @imjohnphan , I have a 2013 GS350 and im facing this exact issue but my car is able to crank over just doesn't start. Were you able to fix it by replacing the fuel pressure sensor?
