I have a 1986.5 Supra non turbo. I changed plugs, wires, cap, rotor, O2 sensor, TPS, fuel filter, and put the timing to 10 degrees. I checked fuel pressure and it is at spec. I did a minor check for unplugged hoses causing vaccum leaks. I check my fuel pressure regulator and that was fine too. Im not sure what to check or replace next. Does anyone have any ideas???

I changed the fuel filter and ran injector cleaner threw the system the last 2 tanks of gas. I will chack more vaccum lines when i get a chance.
Can it be my fuel pump??? Do you think im getting pressure but not volume? I do sometimes have extended cranks
