It should start up after it has fuel preasure. Check the fuel pump and relay.

the pick up tube on the fuel pump is probably broke or you were parked on a hill
Leaking brake cylinder (or caliper piston if it has rear disc brakes). Also if its a rear wheel drive vehicle it could be differential oil leaking from the outer axle seal. If its a brake fluid loss you can monitor the fluid level in the master cylinder .
Maintenance Required LightTurn ignition to 'ACC' and press the odometer button until the display reads actual mileage... not Trip A or B.
Turn ignition off.
Hold in the same button you used in step 1.
While holding the button in, turn ignition to 'ON'.
The 'Maint Reqd' light should blink and go out.
If you wish to confirm, this info should be in your owner's manual.
-- for the 2004 Highlander
Same as above except turning to ON did not work for me but turning to ACC did.
For me..... and I have a 2005 Highlander, I had to hold the odometer button down for several seconds, In my case I had to hold it down for 6 seconds.
For my 2007 Highlander you turn the ignition to ACC press the odometer button, turn it to off, then turn it back to ACC (not "ON") while still keeping the button depressed. The dealership had it wrong, as well.
