1986 MKII Starting Problems Cold or Hot

Hello, I'm having trouble determining the reason my supra is slow to start. Cold or warm after sitting awhile (more than 5 or 10 minutes) it takes about 20-25 seconds to start. Cold start injector was replaced with no change. Now, I tried turning the ignition on but not cranking waiting about 20 seconds, start cranking and it starts after 2-3 seconds. All of this without depressing the pedal. Any ideas? Could this mean its losing fuel pressure? How would I check this? I see no evidence of leaking anywhere, no fuel odors. Also, just replaced plugs, wires, cap and rotor. Once its running it runs great with no indication of a problem. Thank you..

You might want to inspect the fuel tank for junk and clean the little sock filter. Then, perhaps a new fuel filter and pump.
You can jump the yellow connector near the AFM with the key on to get the pump going.and build up pressure in the system.
