So I finally put together my engine after a long rebuild and tried to start her, but there is no spark. Car is Mr2 mk1.
Engine is cranking. Rotor is spinning, but there no spark.
ECU is alive, I shorted T and e and all I get is one flash and then pause, and then one flash. Nothing more.
Tried a new battery. Still no spark.
I have grounds in the correct spots as per BGB. Only thing I'm not sure is this thing

I have grounds on thermostat housing, on the batter stand, on the T-vis, on the fuel filler neck bolts, on head on engine lift bolt (galvanized, is that a problem?), and on that spot right above the fuel filler neck.
The parts where the grounds are have been painted, but I sanded the ground spots to make sure. Could this be it?
Before I knew there was no spark I shorted Fp and B to check if the fuel pump works and to get fuel into engine via cold start injector. Fuel pumo works fine. This worked for me last time when the engine would not start. I then tried cranking and there was an extremely loud bang and fire from the exhaust. I tried again. Another huge bang. I realized this was because I flooded the engine with fuel and there was no spark. Could this have damaged the engine?
I checked TPS with multimeter before rebuild, was fine. Didn't touch it since.
I don't thing I have vacuum leaks. I replaced every single hose and connected everything as per BGB.
I connected a timing light to the #1 spark just to make sure, and of course there was no flash.
Please help me, what should I troubleshoot next?
