Supra2NR...why am I not suprised...
what did you do before it stopped working? or was it running fine last night...and suddenly this morning wont start kinda thing?
I hate to state the obvious, but is it out of gas?
Check to make sure nothing is disconnected that wasnt already disconnected last time it was working...(coil wire, etc.)
also there is a main circuit breaker for the car and at least 2 fuses that will keep it from starting...check those
if all that looks ok...take the number 1 spark plug out, and while holding the threads against a solid ground (I recommend using rubber handled plyers for this) have someone crank the engine...do you get spark at the plug and is it blueish or white/yellow/orangeish? If no spark you want to start with things like distributor, coil, ignition, etc.
If you got spark then the next thing to check is for Fuel pressure...there is a bleeder valve on the fuel rail (kinda like a tire valve) press it down a little and see if fuel squirts out...if it doesnt then you need to check things like Fuel pump, filter, fuel regulator, etc...
Good luck
