alright here is the situation. my motor is an itr head on gsr block, with obd-0 wiring, in a DA

With the distributor fully advanced, my motor is firing at 0 degrees. when the light flashes on the timing light, the white TDC mark is lined up with the mark on the cover.

I know it should be firing at 16 degrees BTDC, but I can't advance the distributor far enough to get there.
The car also doesn't advance when I'm at wot.
The car runs pretty well, good enough to daily drive but severely under powered.

yes I jumped the connector
Timing belt is on there right, cams and CS pulley are all lined up. my firing order is correct, 1,3,4,2. I've tried 3 different distributors, 8 different ECU's, and I rewired my entire car from dash to headlights. still the same problem

 

bump, and I can't stress enough how bad I need this fixed, someone has gotta have some ideas
