hey Kyle,
have you tried a diagnostic on your supra? get a piece of wire and jump TE1 & E1 and turn the car over to ignition and count how many times the engine check light flashes, if you have any probs feel free to email me
spite_girl@hotmail.com
also see if you can borrow an air flow meter from another supra and see if that helps
what sort of supra do you have?
another idea would be to reset the ecu... pull out the main fuse and the efi fuse for about 30seconds and then put them back in and try to start the car
i would suggest doing a diagnostic first
hope this helps
Cheers
Suze
