Hello, and welcome to FIxYa.
To erase the check engine light on a 1994 Camry, open the hood, and, in the engine compartment fuse box, remove the blue 15 amp EFI fuse for one minute. This will clear the codes. If you have a hard code; ie a malfunctioning sensor, the light will come right back on.
Thanks for choosing FixYa for assistance.

I have been researching your problem for two hours and can find no reference to indicate what would cause this. It's possible that a fuse or relay going to the fuel pump is not working, and the scan tool is basically bypassing the fuse or relay and allowing the fuel pump to operate. The other thing that came ot mind was the immobilizer being activated due to an interruption in the battery power to the computer, and the scan tool is temporarily bypassing the immobilizer. Are you getting any codes from the scanner which might indicate a problem? I am assuming your diagnostic port is located in the pull down fuse box which is hidden behind a door in the dash. Once you unplug the scanner, make sure the fuse box is returned to the stored position before trying to start the engine. These are only suggestions that, hopefully will help solve your dilemma. Quite frankly, I am baffled at this point.
