Solid check engine for 30-60sec then ok

so straight to the point.... When key is turned to the on position, I get a solid cell from 30-60 seconds, followed by the cel going away and then the main relay clicks and fuel pump primes. if I try to start while solid cell the motor will crank but no fuel so no start. once the motor is started no issues runs and drives fine. I assumed the main ground at thermostat was the issue and the ecu was slow from a poor ground but harness has been pulled/rewired and is not the issue. do not have a obd1 ecu on hand to swap in and test sadly...
Looking at the ecu, both lights go green when the key is first turned to on, followed the 1 green light going out. after 30-60 seconds the red light will flash once, the 2nd green will come back on, and then the car will supply power to main relay and prime the fuel.

new ignition harness, new main relay, new fuses under dash/under hood, pulled engine harness and rewired few things + thermostat ground, rewired the sub harness that connects chassis harness to ecu. issue was present prior to these fixes/updates cause old car.
