Default car has no spark and wont start. help

So the cliffs notes. car started and drove fine. 8 hours later wouldnt start. Problem is there is no spark coming from the coil...Starter, battery, alternator, plugs, wires, cap, rotor, igniter and coil have been replaced. What the hell am I missing? car cranks, but doesn't even attempt to start
Car is a 93 sc300

with the key in the on position the cel doesnt stay on to indicate its storing a code and when I jumped the e1 and te1, I got nothing.

Have you looked into the cam or crank sensors yet?

Yeah...just found that the pre 97 sc300's get crank and cam signal info from the distributor, as they dont have actual sensors. Seeing as how its the only ignition related piece I havent swapped ima throw a new one at it and see what happens

Have you checked your ECU? Try opening it up and looking for leaking capacitors or borrow someone else's ECU.

On my 1jz I recently had problems with spark. It would crank fine but wouldn't get spark. I opened up the ECU and realized it was leaking. I got it rebuilt and now it's working perfect.

Well with everything ignition wise being new, it looks like ecu may be the culprit...don't they usually give some warning signs of capping out though?

Oh on my 93 the cam and crank info comes from the distributor which is also new
