Engine cranks, but no spark, im stumped Options

[hitcachi]

Well for a little over a week now the Celica has been down. As the title says, it cranks normal but i have no spark. I have replaced so far, the timing belt (because thats what i thought it was at first before i checked for spark), distributor, ignition coil, and igniter. All fuses are good. Very expensive so far and I'm getting frustrated because its still not getting any spark. Reading some past posts, it might be the Starter relay, i haven't replaced that, but i don't know how to test it before just going out and buying a new one. If anyone can offer any suggestions or help i would really appreciate it. Thanks.

how exactly are you checking for spark?

have you tried the started fluid test? spray starter fluid down the throttle, stand back and give it start. If it makes any form of noise then its not your ignition system, its fuel related.

If you don't hear a pop or different noise then its for sure ignition.

Does the distributor spin and the rotor point to the right spark plug at top dead center?? like 97lestyousay asked?
