[BNASTYs13]

I have a type x black top swap in my s13 and it always cranks up first try when it is cold. It runs great aswell. I can drive it around for hours no problem. If i park to go eat or something it will not start back up for an hour or so like its flooded.

I know It is flooding because if i unplug all of the injectors the car will crank up and idle for a few seconds on the fuel thats in the cylinders. It has good spark aswell. I could pull codes but i have a J4 ecu so there is no diagnostic screw on the ecu. I do not have nissan consult.


When a car is first started in closed loop the ecu gives it a little extra fuel. I wonder if my ecu is bad and is stuck in a cold crank setting when i am trying to crank the car when it is warmed up?

I put a new coolant temp sensor on it but that didnt help at all. still the same exact problem. I wish i had a local person with a j4 ecu i could try out.
