I have a 1990 N/A that ran great. My girlfriend's brother decided to borrow it and blew the engine. So luckily i had my wrecked 88 N/A and i decided it would be an easy swap. Well it was kinda, sorta, not really easy swap. the mechanical stuff was easy but the electrical stuff is whats killing me. I had to use my 90 wiring harness and my buddy thought it would be a good idea to just cut the injector wires and then just crimp them back together. WRONG! they corroded into a nice little green connectors. So i fixed that by soldering and shrink wrapping them. Then while i was finishing the wiring install i realized i had missing a connector. The 88 has a VSV FPU (Vacuum Switch Valve Fuel Pressure Up). I guess when u go full throttle it boosts the fuel pressure by like 6-8 psi or something. Well my 90 didn't have that. So i am a little confused on what to do because i dont have my 90 engine anymore so i can't transfer the stuff and no junkyards in central Indiana have supras that haven't been severely molested. On top of all this my fuel pump isn't kicking on. I have power to the main EFI relay but i dont have power at the circuit opening relay. I know the fuel pump works because when I put the jumper wire between the B+ and the Fp connectors on the diagnostic port it kicks on and has plenty of psi. I haven't had time yet to completely test the wires yet but i just want some advice on what it might be and what i should do about the VSV FPU. I have tested all of the relays and they all work fine.
