B18c7 warm start issues - temp sensors??

I'm posting in ere because its an integra engine and there's no hybrid section.
But I am trying to finish an ek b swap with the 2000 integra type r engine - b18c7.
But, it will only start in the cold. Not hot. As in early mornings and late nights.
Once it's been running and shut off it won't start back up again.
I've been trying to fix it and told time and again that its wiring. But I'm thinking its temperature related due to it being the factor.
Has anyone had this before??
Once started in runs rich and kinda different. I've never driven a b series so I'm not 100% sure if its correct or wrong...
Seriously please help. I want to drive my civic again :(

Okay. So I took out the iat sensor and it appears to have short out. Great.
But could it be causing it to run so rich??

So replaced the iat with one from wreckers. Returned all wiring to factory. Still the same issue. Cool nights and mornings fine. Not during the day.
Other ideas?? Map sensor? Coolant temp sensor??

Warm start issues could be related to the CTS. Try replacing it, not too expensive.
Also look at the injectors, warm start issues may be related to the fuel delivery.
When the car has warmed up, the heat from the engine could boil the fuel in the injectors which will need fuel pump priming to get the fuel pressure back to normal.
Just a guess though, please correct me if I am wrong.

but its not even when the car has warmed up. its the simple temp of the air and sun that is causing the issues :/
but i'll check the injectors tomorrow.
however, what is the cts?

sorry. coolant temp sensor?
i have checked both sensors, coolant pissed out everywhere. there doesnt seem to be any damage to the inside of them, ill google ways to test each of the temp sensors and run through them all tomorrow.
could it be due to anything else? could it be timing related or distributor related??
also could i lose spark if the engine is flooded? is this a feature in the ecu to prevent damage to the block??

ECU could be causing this.. I had an issue with this a while back when cold the car would start fine but when warm, not sure WHY but when warm, you wouldn't get a signal back from ECU after key was turned and no lights would be on the dash at all.

nah im getting fuel pump priming, all lights on dash work fine except for the battery light which is staying lit.
no cel. nothing...

Main Relay - likely needs re-soldering.

Search it here on OzHonda.

I've got three that I've been trying through. None of the solders have any cracks either

Try re-soldering them anyway. Looks can be deceiving with those main relays.

These usually only short put if you muck up the plugs for IACV, IAT & or charcoal canister VSV
Did you or do you have a MIL ? (engine check light)

Re coolant temp sensor, you check it with a multimeter (resistance at temp) not visually.
