s13 auto ka24de cold start issues

I recently have been dealing with this issue. the issue consists of when i go to start the car in the morning, the only way to get it started is to give it full throttle while cranking it. then i must hold the idle with the gas pedal for appr. 30 seconds then the car will run fine. if i shut the car off after it has been running for a while and start it right back up, i don't have to do that. if i let the vehicle sit for a while and cool down, i have to go through that process again. if i fail to give it gas while trying to crank it when it's cold, the only way i have found to get it started after that is to disconnect the fuel injector harness, crank the car, and then it will fire up and die. then i reconnect the injector harness crank while giving full throttle hold the idle manually for 30 seconds and it runs fine again. i'm coming to the conclusion that it is flooding upon attempting to start. there is no check engine light on. it has new ignition components, such as spark plugs, cap and rotor. please help me come to a conclusion or give me something to try.
