Default car cranks, but no fuel or spark

Hi, I just bought a 1987 supra turbo 5spd and it dosent run. I am working on it, trying to diagnose the problem, but am having some difficulties. What I know is that the engine is not getting fuel or spark. When I turn the ignition on I do not hear the fuel pump run and the check engine light does not illuminate. The engine will crank over. I have checked all the fuses/relays and they all are ok. When I try to jump the fuel pump at the diagnostic port (b+ and fp), the fuel pump does not turn on. I have no power at b+ in the diagnostic port. When I run a jumper from the positive battery terminal to the fp port in the diagnostic box the fuel pump works. At the ecu I have power at the batt terminal and e1, but no power between e1 and +B, e1 and +B1, and e1 and IG SW. I have no power also when going to body ground instead of e1. So does anyone have a clue what problem this might be? I am thinking either ECU or ignition switch? Do these go bad often? Thanks for any help.
