Tell us more about the setup. I checked the link but the information given is limited.
It's it's a B series Frankenstein automatic.
Yes runs fine after but I do let it warm up before I drive...like when it's hot it turns in fine but the other hand cold not so good even if I leave it 11 hours at work turning it on is ruff ...I hear the fuel pump..it drives fine turns on fast when hot .I did make a video on how it starts ...don't mind the other stuff I got that fixed .just that damn cold start is killing me
My first thought is the fast idle Thermo valve. OBD1 needs a fast idle Thermo valve but OBD2 has such functions controlled by the ECU. So it kind of depends on the ECU and if the throttle body has a fitv. I believe its function is to help idle at cold start. Maybe you do have an fitv but it's is stuck?
The fact that it's an automatic makes me feel like it could be something I am not knowledgeable about.
Can you get it to run normal at a cold start if you give it some gas?

Do you have a FITV or is it a OBD2 TB? Seems most B16 heads in the states are out of a 99/00 Civic Si so that's why I ask.
Hard to believe it's the fuel pump (based on the problem being cold start only). Fuel filter is an easy change (but rarely this "miracle fix"). Injectors can be checked and cleaned for cheap. Maybe the OEM FPR is bad?
Soooo what your saying is we dont have the information here to diagnose your car... not going to be fuel pump or filter, yea id also put a stock FPR back on, 0 performance gain changing it from oem

Long as you havent messed with it shouldnt have to touch the tps, are you using all the same obd generation electronics ?
Map sensor is plug and play but I think it should be for a B series VTEC that matches OBD for ECU.
Id run everything obd0 bseries vtec
