Please Help -Overheat issue (just swapd)

[503Ryder]

I have a 97 civic Lx 4dr Just did swap D16y7 like my last engine (legit comp tested engine) so im sure wire harness and all is good i replaced a s*** ton of fuses. My temp guage does not work, and soon as the car starts the engine gets hot FAST headers heat up, and radiator hoses get hot also and fan not kicking on. and of course CEL is on, and gives me random codes (7 long and 2 short,7 long 3 short...witch is Misfire LOL) and flashes on the srs light and not the cel light

Sounds like the wiring is not all hooked up right for starters, the fan not kicking on could be your temp sensor..could be the fan motor is bad or the power to it is not hooked up right... When you did the swap you swapped the harness as well right? did you swap ECU's?

Confused... so is the CEL light or or not? lol.

Make sure you didn't switch any connectors up (easy to do), I think IAT & TPS have the same plug types, etc.

BOTH hoses get hot, right?

Flushed and bled coolant?
