I checked and in my 2019 AJ126 I don't seem to have the "Fuel pump disablement status" option, and the "Crash status" leads nowhere - just starts a timer that doesn't seem to end.
Maybe someone with an earlier model AJ133 could check.
I assume Clubairth is asking the OP if the car has been in a crash.
This is from the workshop manual. If the Restraints Control Module (RCM) fires any restraints (airbags, pretensioners), then it also shuts off the fuel pump. This claims that’s reset by cycling the ignition, which isn’t happening for you. So maybe this isn’t what caused your fuel pump to be disabled. My car’s in storage, so can’t check it.
CRASH SIGNAL
When the RCM outputs any of the fire signals, it also outputs a hard wired crash signal to the ECM
(Engine Control Module) and the CJB, and changes the output message on the HS CAN powertrain
systems bus from 'no crash' to 'crash condition'.
On receipt of the crash signals:
The ECM disables the fuel tank pump
The CJB enters the crash mode and:
Activates all of the unlock signals of the vehicle locking system, even if the vehicle is already unlocked, repeatedly for 3 seconds, in case an interior lock switch is pressed (locking the door) during the crash
Ignores all locking and superlocking inputs until the crash mode is cancelled, when it returns the locking system to normal operation
Activates all of the courtesy lamps, except for the approach lamps. The activated courtesy lamps remain on until the crash mode is cancelled, when they return to normal operation
Activates the hazard warning lamps. The hazard warning lamps remain on until the crash mode is cancelled.
The crash mode is cancelled by cycling the ignition mode.
No. The car got caught in a snow storm and was caked with salt in my garage for 2 weeks. Unfortunately the temps were too low to wash it for that period of time. I’m wondering if the salt corroded a connection or it could be completely unrelated.

Curious how this procedure is performed.
I’ve read it is pushing the start button on and off several times without your foot on the brake. The other option is to disconnect the battery for at least five minutes. I’ll try the latter this weekend. Wrapping up some other service on the car.
I may have been chasing my tail. Not sure. I tried the battery disconnect and the car still wouldn’t run.
I then resigned myself to having it towed, put back on my bumper (unrelated), and then the air intake. And then I tried one last time and it started AND RAN! YES!!!
Could the air intake being off have caused the car not to start? Is there some kind of vacuum that the car picks up in the intake before it will start?
I have to button it up fully tomorrow and then will see if it starts and warms up in the driveway, without any issues.
@shashi27 That is great news! Was the MAF sensor still connected when the air intake was disconnected? I believe it prevents the car from running for more than a second or two after startup unless it is disconnected.

Yes. I’m a dumb dumb. I was getting worried my car had experienced a catastrophic issue. Now I’m just wrapping up a 10 year service.
