Icon5 '93 Del Sol dies when starting but runs fine

Hey folks, I've got a '93 Honda Del Sol Si 1.6L, with the D16z6 engine.

Recently I've been having issues with starting the car. The car will start up, but then die about a second later. Did this over and over, same result. Tried turning the key back and forth (with car off) to prime fuel pump, same result. I gave the car a little bit of gas, but it still died around 3k RPM.
I finally managed to get it started by flooring the accelerator and holding it at around 5K for a few seconds before letting it idle. Once the car is started, it runs+drives perfectly fine.

I have recently replaced sparks + fuel filter, and cleaned TB. Based on my limited car knowledge, I'm leaning to an issue with the fuel pump relay.

What do you guys think? Anyone else had this issue?
(I should add that this issue is only starting now that the car is parked outside in 90+ degree weather, never happened all winter. Maybe just a coincidence that it's doing this now, but thought it worth mentioning regardless)

Sounds like the engine idle speed may low.

Post the CEL codes.

CEL isn't on, still worth it to check for codes?
