Man...Confused
 

Well, I have fuel and spark on my 87 Supra...(Non-Turbo)

But it still won't start up...what should I do!!! I am going insane trying to figure this out.

by fuel you mean proper pressure? and by spark you mean nice bright blue? if you got those two things and it still wont start...the only thing left really is air...


bad AFM? obstructed intake? broken butterfly valve? massive vacuum leak? is the computer storing any codes?

Timing and or compression is also a key. Worth checking to rule it out..

Air, fuel, compression and spark in the proper order and amounts..
