well after i installed my FMIC i noticed that my car takes a LONNNGG time to start up during cold starts in the moring.
after it starts it runs PERFECT. warm starts no problem.

sometimes it just CRANKS AND CRANKS i held it for about 10 seconds this morning. did it again.. then the starter just starts to bog.(not dead battery) then i wait for about 5 min.. then it starts up jsut fine.

ive tryed alot of things. i even let the fuel pump surge 2 times witch is more then enough. now my car runs perfect when it runs. my battery is located behind the passenger seat(temp) and it grounded on the seat rail.

looking for any ideas that you guys may have.
thanks guys!

check maf ??? what is everything that was taken off the car before FMIC install?? Run through everything and test it out.

i had a problem like that and the orange wire coming from the dash plus to the ecu wasnt hooked up for cold starts.

that white plug has a orange wire thats the "ignition start" wire. Directly above the stock ECU location there is a dash plug. That wire needs to be ran up and spliced into the orange wire up on the dash side.
